Stock levels for the camera are good in every country that we have looked at.</p>



<p class="wp-block-paragraph">We think this camera is going to be a slow burn sales wise with its new ergonomic design and the fact that it's $1899. The EOS R8 is a beloved camera for shooters that have no interest in $10,000 kits and with the launch price bump for the <a href="https://www.canonrumors.com/canon-eos-r8-mark-ii" title="Canon EOS R8 Mark II" class="pretty-link pretty-link-keyword prli-keyword" data-prli-link-id="997" rel="nofollow sponsored noopener" target="_blank">EOS R8 Mark II</a>.</p>

  <h2 class="cr-sec-title">EOS R6 Mark II vs EOS R8 Mark II</h2>
</div>



<p class="wp-block-paragraph">The Canon <a href="https://www.canonrumors.com/canon-eos-r6-mark-ii" title="Canon EOS R6 Mark II" class="pretty-link pretty-link-keyword prli-keyword" data-prli-link-id="912" rel="nofollow sponsored noopener" target="_blank">EOS R6 Mark II</a> is still a current product and is only $100 more currently and we think there is going to be a lot of cross shopping between the two cameras. On the surface, I'd take the <a href="https://www.canonrumors.com/canon-eos-r8-mark-ii" title="Canon EOS R8 Mark II" class="pretty-link pretty-link-keyword prli-keyword" data-prli-link-id="997" rel="nofollow sponsored noopener" target="_blank">EOS R8 Mark II</a> for what I'd use it for, but for people that want or need a mechanical shutter, the <a href="https://www.canonrumors.com/canon-eos-r6-mark-ii" title="Canon EOS R6 Mark II" class="pretty-link pretty-link-keyword prli-keyword" data-prli-link-id="912" rel="nofollow sponsored noopener" target="_blank">EOS R6 Mark II</a> is going to be the better choice.</p>



<p class="wp-block-paragraph">Features like pre-shooting don't matter to everyone and there are a lot of other software tricks that may be of no interest to a lot of consumers.</p>



<p class="wp-block-paragraph">The <a href="https://www.canonrumors.com/canon-eos-r8-mark-ii" title="Canon EOS R8 Mark II" class="pretty-link pretty-link-keyword prli-keyword" data-prli-link-id="997" rel="nofollow sponsored noopener" target="_blank">EOS R8 Mark II</a> does not have the same video chops as the <a href="https://www.canonrumors.com/canon-eos-r6-mark-ii" title="Canon EOS R6 Mark II" class="pretty-link pretty-link-keyword prli-keyword" data-prli-link-id="912" rel="nofollow sponsored noopener" target="_blank">EOS R6 Mark II</a>, so that will be a consideration for some.</p>

  <h2 class="cr-sec-title">EOS R8 Mark II Initial Impressions</h2>
</div>



<p class="wp-block-paragraph">I am not a reviewer and I have zero desire to be one. The zero day reviews for the EOS R8 Mark II all kind of said the same thing. There was a lot of focus on the design language and I think that had a lot of influence in the tone of the reviews.</p>



<p class="wp-block-paragraph">There was also the whole &#8220;retro&#8221; thing that we started. Canon says it's retro inspired, and with the EG-E2 <a href="https://www.canonrumors.com/canon-eg-e2-extension-grip" title="Canon EG-E2 Extension Grip" class="pretty-link pretty-link-keyword prli-keyword" data-prli-link-id="998" rel="nofollow sponsored noopener" target="_blank">ergonomic grip</a>, there is some visual cues that look like a throwback to yesteryear.</p>



<p class="wp-block-paragraph">Zero day reviewers do not have gear for more than a week or two in a lot of cases, even less time sometimes, so they have to get things out there as best as they can. The reviews that are going to come a month or 6 months from now are going to paint a different picture I think. Whether that's in a positive or negative way, we'll see.</p>



<p class="wp-block-paragraph">There will also be a demographic of people that hate big change in the way a camera is physically designed, and that's ok.</p>



<p class="wp-block-paragraph">As for our initial impressions now that we have the camera?</p>



<p class="wp-block-paragraph">I much prefer the new design language over the R8, and the camera feels a bit more premium. The grip material feels a lot better than the EOS R8. Overall the new 8-series camera feels a notch higher than the R8.</p>



<p class="wp-block-paragraph">I also ordered the <a href="https://www.canonrumors.com/canon-eg-e2-extension-grip">Canon EG-E2 ergonomic grip</a> and it is really well executed and makes a significant difference for me.</p>

<p class="wp-block-paragraph">At $1,899, the price doesn't feel entry-level, full-frame or not.</p>



<p class="wp-block-paragraph">I can assure you that this won't be Canon's entry-level full-frame camera at some point in time over the next year. For now, we're calling the coming <a href="https://www.canonrumors.com/the-eos-r8-mark-ii-might-not-be-canons-entry-level-full-frame-camera/">entry-level camera the EOS R9</a>.</p>



<p class="wp-block-paragraph">There is going to be hardware they'll be able to remove from an entry-level camera to bring the price down significantly from $1899.</p>



<p class="wp-block-paragraph">If the price of the EOS R8 Mark II is too steep for you, I think we're going to see it appear at the Canon USA Refurbished store a bit earlier than most other cameras. This may be a camera worth waiting 6 months to save some money.</p>

<p class="wp-block-paragraph">I look forward to putting the EOS R8 Mark II through its paces alongside the EOS R1 this weekend. I'm not a fan of iPhone vs ARRI camera nonsense but I do enjoy seeing what the &#8220;normal&#8221; consumer buys vs the flagship professional products.</p>



<p class="wp-block-paragraph">Yes, the EOS R1 is going to outperform the EOS R8 Mark II by a large margin when it comes to autofocus and sensor readout speed, but it'll be interesting to see if the R8 Mark II is better or equal at some other things.</p>



<p class="wp-block-paragraph">I think Canon has done well here.</p>

<h2 class="wp-block-heading">In Closing</h2>



<p class="wp-block-paragraph">The firmware is nice, but it's strange to see that Canon really only has 3 Cinema EOS cameras. We suspect a camera or two above the C400 are coming, but we have no idea when.</p>



<p class="wp-block-paragraph">It feels like we've been waiting forever, but we think Canon is going to re-imagine the higher end level of cameras. Sony is the big player, and it seems the higher budget filmmakers simply don't look at Canon and roll with Sony and ARRI.</p>

<p class="wp-block-paragraph">A small group of us are quietly waiting for an RF 200mm f/2L IS to become part of the RF lineup, but we know it's a niche lens and we'll have to be patient. Maybe we're not getting a prime and Canon will go the zoom route again, as they did with the RF 100-300mm f/2.8L IS USM instead of a straight 300mm f/2.8 prime.</p>



<p class="wp-block-paragraph">In a recent patent, Canon shows off an optical design for an RF 70-200mm f/2L IS, and that would be cool. Since the RF 28-70mm f/2L became a thing, there have been endless desires for Canon to add an f/2 version of the 70-200 series to pair with it. Great idea, and all it will take is a big bag of money to get one.</p>

<p class="wp-block-paragraph">This patent has more to do with moving focusing groups to keep the size of the design as small as possible and to preserve image quality at the minimum focusing distance, the optical designs presented are using 3 focusing groups.</p>



<p class="wp-block-paragraph">All three of the focusing groups move towards the subject for close focus. The main focusing group is labeled &#8220;F3&#8221;, the &#8220;F1&#8221; and &#8220;F2&#8221; groups move only a tiny amount to offset field curvature. Since the two latter groups only move a little bit according to the patent, they don't need large focus motors as the elements in those two groups don't have to be thick and heavy.</p>

</div>



<p class="wp-block-paragraph">In a patent application with about a dozen optical designs, the RF 70-200mm f/2L is the one that stands out. It's not small with a lens length of 220mm without the added flange distance. The EF 200mm f/2L IS USM was 210mm in length, but as a whole package. How lens lengths in a patent translate to an actual consumer product doesn't always follow a standard set of rules.</p>

<p class="wp-block-paragraph">The design is fairly complex as you'd imagine with 23 elements in 8 groups with 6 aspheric surfaces. This looks to be an internal zoom design as well.</p>



<p class="wp-block-paragraph">We're not saying it's happening, but if we could preorder based on a patent application, we'd have done so already. Sure, a smaller and lighter RF 200mm f/1.8L IS would be just fine as well. We're not picky, just whiny.</p>

We still think it's a <strong><em>very small chance</em></strong> and it would cost $6000-$8000 from our friends at Canon. </p>



<p class="wp-block-paragraph">The other examples in this patent are for "normal" f/1.4 zoom lenses like a 50-85mm f/1.4.  That's not something Canon would make, but there seems to be a lot of recent filings pointing towards zoom lenses faster than f/2.</p>



<p class="wp-block-paragraph">As always, this may be much ado about nothing and we're just showing you what Canon is up to.</p>

    All 11 examples are full-frame zoom lenses with a constant maximum aperture, and every one focuses with three or more independent focus groups. F1 is a single negative element in the main negative zoom group, F2 is a single positive element near the aperture, and F3 is the main focus group. All three move toward the subject when focusing close. Example 11 adds a fourth focus group that moves toward the sensor. Lens groups are numbered L1, L2&hellip; as in the patent. Lengths and back focus are given wide &rarr; telephoto. Closest focus is measured from the image plane. Badge shows the lens class.

  <h2 class="cr-sec-title">The Patent Solution</h2>
</div>



<p class="wp-block-paragraph">If we're reading this one correctly, Canon is using a new class of glass with a refractive index of 2.2-2.3, which is beyond what we traditionally see in lenses. Those don't tend to go beyond 2.0.</p>



<p class="wp-block-paragraph">What does that mean? If you use elements with a higher refractive index, you end up bending the light in a stronger way. That allows thinner lens elements, which shrinks the length and weight of a lens.</p>



<p class="wp-block-paragraph">The problem with high-refractive lens elements is that they spread colors out more, which is extremely hard to control and you tend to end up with wonky color errors. </p>



<p class="wp-block-paragraph">It looks like Canon is using two of the high-refractive lens elements to correct the issues with violet dispersion, which tends to be the color most affected.</p>

<p class="wp-block-paragraph">The patent shows off a few interesting lens designs for both full-frame and APS-C sensors. Of them, the 85mm f/1.2 example is the most interesting to us, as we do believe <a href="https://www.canonrumors.com/is-the-rf-85mm-f-1-2l-v2-coming-canon-patent-details-dual-motor-focus-design/">we're getting a replacement</a> for the current version in the coming months.</p>



<p class="wp-block-paragraph">The APS-C 65mm f/1.4 is interesting as well, but we haven't seen much evidence that Canon has interest in making fast prime lenses for crop cameras.</p>

<p class="wp-block-paragraph">This patent is less about a specific lens and more about a material that could shape all future lens designs from Canon.</p>



<p class="wp-block-paragraph">Two well-placed high-refractive elements of it are enough to shrink an 85mm f/1.2 or a 135mm f/1.8 without giving up image quality, as claimed in this patent.</p>



<p class="wp-block-paragraph">We do our best to understand these patents, but if you find something that isn't quite right, please let us know.</p>

    All 4 examples share the same 14-element, 5-group layout &mdash; positive, negative, negative, positive, then a weak rear group. The front (B1), third (B3), and rear (B5) groups stay fixed during focus, while B2 slides toward the sensor and B4 slides toward the subject. The aperture sits between B3 and B4. Each design uses two ultra-high-index elements (nd &asymp; 2.2&ndash;2.3): Lp1 at the very front and Lp2 in the rear group. These are fixed-focal-length lenses, not zooms. Image height: 21.64mm (full-frame) for Examples 1&ndash;3, 13.66mm (APS-C) for Example 4. Badge shows focal-length tier.

<p class="wp-block-paragraph">The 16-50mm f/2.8 A is Tamron's fourth lens for the RF mount following the <a href="https://www.canonrumors.com/buyers-guide/?tab=lenses&brand=tamron">Tamron 11-20mm f/2.8 Di III-A RXD</a>, <a href="https://www.canonrumors.com/buyers-guide/?tab=lenses&brand=tamron">Tamron 17-70mm f/2.8 Di III-A VC RXD</a> and <a href="https://www.canonrumors.com/buyers-guide/?tab=lenses&brand=tamron">Tamron 18-300mm f/3.5-6.3 Di III-A VC VXD</a>.</p>



<p class="wp-block-paragraph">Tamron's goal here is an affordable, lightweight and constant aperture zoom, and it looks like it'll check most boxes for $500. To keep things small and light, at only 305g, Tamron didn't equip the lens with Vibration Correction, Tamron's version of image stabilization.</p>



<p class="wp-block-paragraph">There is only one Canon APS-C camera with IBIS in the <a href="https://www.canonrumors.com/canon-eos-r7" title="Canon EOS R7" class="pretty-link pretty-link-keyword prli-keyword" data-prli-link-id="141" rel="nofollow sponsored noopener" target="_blank">EOS R7</a>, but we expect that to change for the lineup refresh that begins in the next few months.</p>

<p class="wp-block-paragraph">On the physical side of things, the 16-50mm f/2.8 A uses a 55mm filter thread with a barrel length of 79.6mm, making it ideal for gimbal use for hybrid and video shooters. The lens also comes with some level of weathersealing, which is nice to see on $500 lenses.</p>



<p class="wp-block-paragraph">The Tamron RF 16-50mm f/2.8 A <strong>begins shipping on October 29, 2026</strong> for $549 · €499 · £419.</p>

<p class="wp-block-paragraph">As with any lens in the area of $500, there are going to be optical performance design choices to appeal to the most potential customers as possible, but nothing will be perfect for everyone.</p>



<p class="wp-block-paragraph"><strong>At 16mm</strong>, the contrast is great across the entire frame and even better for the RF mount since Canon's APS-C sensors are slightly smaller than sensors from the likes of Sony or Fujifilm.</p>



<p class="wp-block-paragraph">Sharpness at 16mm is good and consistent across the mid-frame, but out to the extreme corners you will see sharpness fall off pretty quickly, so be aware of that when shooting. If you're shooting landscapes at 16mm and you're not stopping down, give yourself some pixels on the edges to crop when thinking about composition.</p>



<p class="wp-block-paragraph"><strong>At 50mm</strong>, contrast slowly falls off from the center to the corners, and you probably won't notice that in real world shooting. There will be some astigmatism towards the edges at 50mm, but again, if you think that's going to matter, compose with that in mind.</p>



<p class="wp-block-paragraph">At the center of the frame, the <a href="https://www.canonrumors.com/tamron-16-50mm-f28-a" title="Tamron 16-50mm f/2.8 A" class="pretty-link pretty-link-keyword prli-keyword" data-prli-link-id="1010" rel="nofollow sponsored noopener" target="_blank">Tamron 16-50mm f/2.8 A</a> is excellent, especially for a $500 lens. Corner performance is the weakness at both 16mm and 50mm wide open, but if you stop down to f/4-5.6, those issues will become far less pronounced.</p>

<p class="wp-block-paragraph">On the RF mount, the new lens has a <strong>35mm equivalent of 80-192mm and weighs only 410g in the RF mount version</strong>. The Sony and Fujifilm versions are a bit lighter at 390g, and with their slightly larger APS-C sensors, they don't have as tight of a field of view.</p>

<p class="wp-block-paragraph">Sigma has now finished a &#8220;holy trinity&#8221; of f/2.8 APS-C zoom lenses, and it looks like a terrific set of lenses. We already have the <a href="https://www.canonrumors.com/sigma-10-18mm-f28-dc-contemporary" title="Sigma 10-18mm f/2.8 DC DN Contemporary" class="pretty-link pretty-link-keyword prli-keyword" data-prli-link-id="1008" rel="nofollow sponsored noopener" target="_blank">Sigma 10-18mm f/2.8 DC DN Contemporary</a> and <a href="https://www.canonrumors.com/sigma-18-50mm-f28-dc-contemporary" title="Sigma 18-50mm f/2.8 DC DN Contemporary" class="pretty-link pretty-link-keyword prli-keyword" data-prli-link-id="1009" rel="nofollow sponsored noopener" target="_blank">Sigma 18-50mm f/2.8 DC DN Contemporary</a> and they're both great as well.</p>



<p class="wp-block-paragraph">The Sigma <a href="https://www.canonrumors.com/sigma-50-120mm-f28-dc-os-contemporary" title="Sigma 50-120mm f/2.8 DC OS Contemporary" class="pretty-link pretty-link-keyword prli-keyword" data-prli-link-id="1007" rel="nofollow sponsored noopener" target="_blank">RF 50-120mm f/2.8 DC OS Contemporary</a> has optical image stabilization rated at 6.5 stops at the wide end, and 4.5 stops at the long end. The lens uses an HLA linear autofocus motor, which is more than fast enough. The optical design also minimizes focus breathing for video and hybrid shooters, but photographers appreciate that as well. On top of all of that, you also get weathersealing.</p>

<p class="wp-block-paragraph">Sigma has been hitting it out of the park with the optical performance of their latest lenses, and the RF 50-120mm f/2.8 DC OS | Contemporary is no exception; the optical performance looks terrific especially for a $799 lens.</p>



<p class="wp-block-paragraph"><strong>At 50mm</strong>, the performance from the center to mid-frame is excellent, there's only a slight drop in contrast, nothing anyone is going to notice. The 30 lp/mm line shows a mid-frame dip before recovering going further out in the frame. This isn't something anyone is going to notice, and it's a fairly common thing with zoom lenses that don't break the bank.</p>



<p class="wp-block-paragraph">The corners look to suffer somewhat, but moreso on Fuji and Sony APS-C sensors since they're a bit bigger than a Canon APS-C sensor. Canon shooters will get better perceived corner performance.</p>



<p class="wp-block-paragraph"><strong>At 120mm</strong>, the entire frame shows great contrast at the long end. This is a pretty good achievement by Sigma, it's rare to see this level of performance wide open. The solid 30 lp/mm line shows terrific detail across the entire frame as well.</p>



<p class="wp-block-paragraph">The only weak point that we see is astigmatism kicking in when going out to the corners. Is this something people are going to notice? Not likely. Do expect to see some softness at 120mm outside of the mid-frame if you peep the pixels.</p>



<p class="wp-block-paragraph">Overall the lens is terrific optically going by Sigma's own MTF charts. Other people may get different results, but we don't imagine they'll be all that different.</p>



<p class="wp-block-paragraph">There is always a design choice with zoom lenses, which end of the range is going to get the better image quality, and Sigma has chosen the long end, which is a good choice. Most shooters will be using this lens at the long end for portrait and sports work.</p>

  </div>

  <div class="pr-body">
    <p><span class="pr-dateline">Ronkonkoma, NY, October 8, 2026 –</span> Sigma Corporation of America, the US subsidiary of Sigma Corporation (CEO: Kazuto Yamaki. Headquarters: Asao-ku, Kawasaki-shi, Kanagawa, Japan), is pleased to announce the <a href="https://www.canonrumors.com/sigma-50-120mm-f28-dc-os-contemporary" target="_blank" rel="noopener">Sigma 50-120mm F2.8 DC OS | Contemporary</a>, a telephoto zoom for APS-C mirrorless cameras that covers roughly 75-180mm in full-frame terms at a constant F2.8 in a compact, lightweight body. It completes Sigma’s constant-F2.8 Contemporary zoom series alongside the 10-18mm F2.8 DC DN and the 18-50mm F2.8 DC DN, giving small format camera operators ultra-wide to telephoto coverage at F2.8 in three lenses that together weigh less than a lightweight laptop.</p>

    <p>The 50-120mm fills the role of the classic 70-200mm F2.8 — the go-to lens for portraits, events and indoor sports — at a fraction of the size and weight. It adds features rarely combined in a lens this small:</p>

    <ul class="pr-list">
      <li>Optical stabilization rated up to 6.5 stops</li>
      <li>A dedicated aperture ring</li>
      <li>A fast linear autofocus motor</li>
      <li>A design that minimizes focus breathing for video</li>
      <li>Dust- and splash-resistant build with a water- and oil-repellent front element</li>
    </ul>

    <blockquote class="pr-quote">
      <p>“Sigma’s Contemporary line has always emphasized an exceedingly compact form factor and reduced weight without compromising our standard for image quality. The 50-120mm F2.8 meets that benchmark while pushing the line forward in build and handling, including an aperture ring not found on its sister lenses.”</p>
      <cite>Mark Amir-Hamzeh, President, Sigma Corporation of America</cite>
    </blockquote>

    <p>The 50-120mm is the first APS-C zoom in Sigma’s Contemporary line to include an aperture ring, a control long requested by photographers and filmmakers who prefer to set exposure by hand.</p>

<p class="wp-block-paragraph">The goal here is to add an extender without increasing the length of the lens just like a built-in teleconverter would do, but this patent is more about showing the importance of where in the lens the teleconverter is placed.</p>



<p class="wp-block-paragraph">The placement of a built-in or drop-in teleconverter has an effect on the size of the lens. We had never thought about this before, but it makes sense. As we all know, manufacturers are all in on making lenses smaller and lighter. We're good with that focus in lens design.</p>



<p class="wp-block-paragraph">As far as the optical design in this patent, Canon is using a 100-300mm f/2.8 base lens and shows the empty space where a 1.4x teleconverter can be &#8220;dropped in&#8221;. Dropped-in can also mean built-in.</p>

<p class="wp-block-paragraph">If we just go with the drop-in part of the patent, we could see it being something to do to keep the price point down on a longer supertelephoto zoom lens. If it's <a href="https://www.canonrumors.com/?s=RF+300-600">something like a 300-600</a>, you could make available a new style of teleconverter to sell to people that want longer reach and not change how the lens feels in your hand and save some money if you have no interest in a built-in converter.</p>



<p class="wp-block-paragraph">Canon would have no problem selling you a brand new type of teleconverter at Canon prices either.</p>



<p class="wp-block-paragraph">The teleconverter is placed toward the rear of the lens. This is to take advantage of the narrowing light path before it hits the sensor. Because the light beam is smaller here, the teleconverter glass itself can be smaller than if it was more forward in the design.</p>



<p class="wp-block-paragraph">We'll have to think more about what a drop-in teleconverter would mean and how it would make a shooter's life better, over simply having it built-in.</p>

<p class="wp-block-paragraph">Canon is going to be bringing new lenses in the near future with built-in teleconverters, or maybe even a drop-in converter. This just seems like a new way to implement a teleconverter.</p>



<p class="wp-block-paragraph">As always, a patent just shows us what Canon is up to, and not always what we can expect to be announced. A drop-in teleconverter would be a new way to do it, but as mentioned earlier, we're not sure why shooters would prefer this solution over just building one in other than up front cost savings.</p>



<p class="wp-block-paragraph">This is definitely an interesting bit of research and development.</p>

    All 6 examples are constant-aperture full-frame telephoto zooms (image height 21.64mm) with a fixed front group and an empty slot behind the last negative group. Examples 1&ndash;3 are the base lenses. Examples 4&ndash;6 are the same lenses with a negative 1.4&times; extender dropped into that slot, which shifts the range longer, costs one stop, and leaves the length unchanged. Badge colors pair each base lens with its extender version.

<p class="wp-block-paragraph">We reported recently that <a href="https://www.canonrumors.com/information-about-canons-coming-macro-lens/">Canon would be releasing an RF 90mm f/2.8 IS STM Macro lens</a>, it will not be an L lens, as the RF 100mm f/2.8L IS USM Macro already exists. We have also seen designs for a <a href="https://www.canonrumors.com/is-canon-finally-replacing-the-legendary-ef-180mm-macro-for-the-rf-mount/">90mm macro lens from a previous patent</a>.</p>



<p class="wp-block-paragraph">This latest patent is similar to the previous patent. The goal is to shrink the size of a macro lens to keep it as short and light as possible.</p>

<p class="wp-block-paragraph">We expect the Canon RF 90mm f/2.8 IS STM Macro to be announced in the next month or so—late October or early November seems to be the most likely, but we do not have a confirmed announcement date yet.</p>



<p class="wp-block-paragraph">We now have three different designs for the RF 90 macro, so we think it's a safe bet that we're going to see something very close to what is shown here.</p>

<p class="wp-block-paragraph">I have received a couple of emails about the possibility of Sigma announcing an RF 50-120mm f/2.8 DC OS in October.</p>



<p class="wp-block-paragraph">This is the type of lens that has been rumored to be coming from Canon for a long time. For a Canon APS-C sensor, this would basically be an 80–200 f/2.8 equivalent, which would likely do quite well for crop-sensor shooters.</p>



<p class="wp-block-paragraph">We've seen some patents for such a lens from Sigma, <a href="https://www.canonrumors.com/sigma-working-on-aps-c-50-140-f-2-8-and-an-external-zoom-full-frame-70-200-f-2-8/">including one from back in 2023.</a></p>



<p class="wp-block-paragraph">Sigma has more than one lens coming for their confirmed announcement dates of October 8 and October 24, 2026. One of them is going to be some kind of prime lens faster than f/1.2. From a marketing standpoint, hit that f/0.95, people love that number.</p>



<p class="wp-block-paragraph">Canon also has lens announcements coming before the end of the year, and one of them will be the RF 90mm f/2.8 IS Macro. That one will be a non-L lens, and we think it'll be similar in design to the RF 15–30mm f/2.8 IS STM and RF 28–70mm f/2.8 IS STM.</p>



<p class="wp-block-paragraph">Unfortunately, 2026 is going to end without any sort of announcement for full-frame Sigma RF lenses, but at least we have some new &#8220;RF-S&#8221; lenses coming from third parties in the next month or two.</p>
