so... are there any camera-related news today???

2009-06-16T23:27:00.004+10:00

i have (very) few rss feeds in my "photo" category in google reader and i get about 5 posts a day on average. today i got 26. and 25 of them were about the new olympus E-P1 micro four thirds camera (the 26th one was some mamiya post from dpreview).

the 43rumors.com blog has a list of links about the camera and dpreview.com has a good preview. available for purchase in july 2009 according to the olympus press release (can preorder now).

i don't like the retro styling (at all) but what can you do... have to buy one anyway. maybe i can spray-paint it black so that it looks somewhat reasonable. good to see that this olympus camera does not have that waste of space called "xD card slot."

so, did you order yours yet?

some rumors about upcoming olympus micro 4/3

2009-05-25T02:51:00.002+10:00

there are some new/recent rumors about the upcoming Olympus micro four thirds camera. dcviews.com (may 22) points to a possible teaser on the olympus asia website which mentions the date may26 ...
gizmodo.com also had a post about this recently. let's see.

new olympus E620 and underwater housing PT-E06

2009-02-26T06:23:00.003+11:00

The new olympus E620 dSLR camera has been annouced, with a matching underwater housing PT-E06. the housing looks very similar to the one for E520 (which i've found very pleasant to use).

Some links with more information:

dpreview.com has a hands-on preview
amazon lists the housing for 1,000USD
There is a thread on scubaboard with an ongoing discussion about the new camera and the availability of the housing for the previous model the E520
dcresource.com also has a preview

new sensor (it seems it might be the one used in E30 from what i read in the previews), 7 AF points, ISO3200, LCD rotation, 4fps, battery is the same as for the E420, expected price 699USD.

it still has that waste of space called an xD card slot ...

more on the 10bar housing for the panasonic LX3

2009-01-07T04:05:00.002+11:00

there is a price list here, from 10bar, which mentions a price of 630 USD for the 10bar LX3 housing. also available here, but the price is ... 905 USD ("availability 3 weeks").

phase versus contrast detect focusing in low light (underwater)

2009-01-02T20:15:00.003+11:00

i ve used my olympus E520 underwater only a few times so far (10 or so) and i've notice that in low light, low visibility, wide angle it has some trouble focusing. In similar situations my previous camera, the canon G7 of course wouldnt focus either, and would never be able to take a photo of any use. the olympus can take good photos but the focusing part becomes slightly noticable.

i also noticed (i think) that in such cases, switching to live-view/constrast detect focus works much faster and possibly better.

i was wondering if anyone had the same experience with similar cameras?

are there cases where contrast detect focus is better than the normal/phase detect focus especially underwater?

panasonic LX3 underwater housing from 10bar

2009-01-02T19:18:00.003+11:00

there is a recent review on dpreview.com comparing a bunch of higher end compacts that finds the panasonic lx3 as the overall winner. the camera is probably one of the best compact options at this time for undewater use. the only problem is that there are no cheap housings for it.

there is a 10bar housing, made of aluminum, that looks quite nice (and expensive..)

there is some information about the new housing on the 10bar website, as well as this thread on wetpixel. the price is reported around 600 USD in the wetpixel forums. the camera is around 400 USD.

the canon g10 is so much cheaper, at 400USD for the camera plus 200USD for the canon housing.

white balancing raw files

2008-11-23T14:23:00.001+11:00

because of technical issues i had to dive with out my strobes today, using only my new olympus E520. (technical issues: i am getting old and keep forgetting things. this time i forgot my tray so i couldnt attach my two strobes to the housing)

i was shooting RAW+jpg. the jpg was at the highest quality setting (probably a bit unnecessary if you have the raw file as well). i was using auto white balance, auto iso and shutter priority on all ambient light photos. i tried some quick white-balancing using picasa and the "pick neutral color" tool on both the jpgs and raw files. i clicked at the same region for the white balancing in both the jpg and raw file (usually a patch of sand or bare rock in the photo).

some samples of post-white-balancing.

the original (jpg, but the raw is very similar looking, not as sharp and with some more highlights),

resulting image after manually post-whitebalancing the jpg file (left) or the raw file (right)

same deal here:

white balance done on the jpg versus raw

and some more examples of applying white balancing on the raw files (original versus white-balanced):

there is a bit of a difference, even with very basic quick fixes (which is all i have time and skill to do). white-balancing raw seems also easier: in the jpg files if you click some seemingly neutral looking color which happens not to be a good area to use, then the photo is all messed up. so some more clicks might be required to get a good result. the raw file is more forgiving it seems. In most of the case in these pictures i used parts of the sand for white balaning (avoiding the highlights on the sand, so i picked the more dark sandy regions). In the photos with the diver (greg) i tried both the sand and the buckles on the tank (good thing he is using steel ones and not black plastic...). the sand was not as good in that particular shot. All photos were taken at bare island east side (left), at roughly 10-12m depth, with seriously crappy weather (rainy windy cloudy cold). visibility was very bad, maybe 4-5m at some points, but maybe a bit more in the last photo above. max auto iso was set to 800 which was not needed, should be ok at 400.

All photos available at my flickr page

new sea & sea DX-2G ?

2008-10-11T17:22:00.002+11:00

as i read on digifish.nl/ sea & sea might release the successor to the sea & sea DX-1G. according to what i read on the web, the new sea&sea will be using the ricoh caplio GX-200 (following information from dprview.com):

24mm f2.5-4.4 lens, 3x zoom
sensor image stabilization
macro at 1cm
manual focus and raw
hotshoe
no optical viewfinder (an external viewfinder can go on the hotshoe)
ISO to 1600
12mp

a few reviews for the ricoh camera are listed on dcviews.com. i dont see a lot of differences with the previous model.

panasonic lx3

2008-10-07T23:50:00.003+11:00

Might be a great camera underwater. Problem is, no housing exists. Yet. I was reading through some reviews about the lx3, including this one, apparently showing a 2 stop advantage (or some advantage..) over the G9 in terms of noise and lens aperture, as discussed here.

One link led to another, and i saw this post on dpreview.com about a possibility that UK-germany is planning to make a housing for the LX3. uk-germany was making a housing for the panasonic lx2, as you can see on digideep. odd looking one for sure.

would be great news. panasonic lx3 looks like a great compact camera: leica f2.0 lens 24-60mm (35mm equivalent), full manual control including manual focus, image stabilization (lens), raw, hot shoe.

cannot find any other information about this at the time.

is there any other information around?

nimar housing for canon 450D

2008-09-26T23:13:00.003+10:00

canon 450D (XSi) is about $700 these days with the kit lens. (USD)

the cheapest housing on the market seems to be the Nimar NI303D, $1150 (USD) including the port (for the standard kit 18-55 lens).

total under $2K, not bad. the nimar housing has a standard nikonos bulkhead. not sure if it works with inon strobes for TTL. (photos are from the nimar site). also the housing does not have a hotshoe on top for fixing focus lights.

the dSLR barrier

2008-09-26T21:59:00.004+10:00

the barrier to dSLR:
(for the following comparison i use canon G10 versus canon 450D)

price

top of the line compact is about 600AUD, housing about 300AUD, total of about 1000AUD
entry level dSLR camera with a kit lens is about 700AUD, housing with a port 1500AUD, total 2200

weight

compact is 390gr, and the housing is next to nothing. total of 500-600gr.
dSLR is 425gr without lens, lens is 250gr, housing 3200kg (ikelite housing for canon 450D), total of 4kg.

size

a compact is compact barely there, can fit in a (big) pocket
dSLR needs an extra suitcase and an extra hotel room to fit in when traveling.

features

a good compact has manual controls, macro, attaching wet lenses, video, all in one
a dSLR is not very flexible (for entry level models), not flexible with strobes

So, from a relatively affordable, $1K 0.6kg small, manageable, easy to travel with, all around camera that can do everything at any time, you go to a very expensive 4kg, huge, not-so-flexible-at-all set up. so (entry level) dSLRs are much more expensive, terribly heavier, ridiculously bigger, horribly inflexible.

and that's good: if we take into account all those issues, the price difference between the top compacts and entry level dSLRs is the least of the problem. as for the rest, well, one just has to get used to carrying a closet around while diving. until technology manages to catch up.

new Canon G10 and WP-DC28

2008-09-17T21:18:00.003+10:00

canon announced the G10 (top of the line compact) as well as a matching underwater housing WP-DC28. (photos are from the canon website)

about the G10:

28mm wide lens with 5x zoom,
i-constrast, which is something that claims to boost brightness in order to retain detail in the shadows. sounds great.
one more dial, for exposure compensation
raw,
1/1.7" CCD sensor with loads of megapixels.

the WP-DC28 housing looks a lot like the WP-DC11 for the G7 (and the one for G9) with a large oval shaped lens barrel which made it impossible to use wide angle wet lenses for the previous models. i guess the same will be true for the G10.

any hope ikelite will choose to make one of their new "compact" housings for this camera? that would be great.

fantasea dSLR housings no more?

2008-09-16T00:00:00.002+10:00

cannot really find much info on fantasea housings for dSLR cameras. did fantasea give up on making housings for SLRs and only makes compact camera housings now?

panasonic G1 - micro fours thirds

2008-09-13T18:04:00.003+10:00

panasonic announced the first micro four thirds camera, the Lumix DMC-G1, along with two micro four thirds lenses, 14-45 and 45-200 that include image stabilization. (the photo is from the panasonic press release)

here are some links to read more:

imaging resource with hands-on preview
dpreview hands-on preview
dcviews.com (press release)
divephotoguide.com (press release)

Panasonic also announced that we should expect a couple more (micro four thirds) lenses early 2009 (one of them is a 14-140). the new panasonic g1 is smaller than the olympus E420 in every dimension (the imagingresource.com site has a good photo comparing the two cameras).

some good things:

23 area auto focus,
very fast contrast detect auto focus (according to the dpreview preview),
electronic viewfinder (optical viewfinders with pentaprisms mirrors and all that, are sooo last century)
depth of field preview
shutter speed effect preview (camera changes the refrsh rate of live view to mimic the shutter speed effect)
3 inch swivel lcd monitor

other things:

video/movie mode? why no video?
and where are the underwater housings?

pricing is expected in early october according to the press release. but this site mentions an estimate of 840USD (inc lens). the camera should be available mid november.

new Nikon D90

2008-08-29T15:45:00.002+10:00

The new Nikon D90 has been announced (see preview on dpreview). the D90 has a new 12.3MP DX format CMOS sensor, offers a movie mode, live-view with contrast detect AF, ISO 100/200-3200/6400, 3" lcd, and image sensor cleaning. There is also a compact gps unit available that connects on the hotshoe.
the price tag is 1000USD (camera body only) on bhphotovideo.com, expected in october.

hmm. i dont know.

i will just continue to look forward to the first olympus micro four thirds camera...

housing for pentax w60

2008-08-10T19:12:00.003+10:00

the pentax w60 was announced on 23-May-2006 (no, no, i am not that late finding out, here, i posted about it earlier..). I just found (through digifish.nl)some information about a Seatool 40m housing for it. But the only page i've seen is in japanese; here is a link to a google-translated version of the seatool.net page.

the page mentions a price of about 350AUD and a release date of august 8. and some accessories, such as M67 adapter, optic fibre adapter, and a close-up lens. Apparently the seatool products are available directly from seatool.net (japanese only) website. You can buy all the w60 goods here (again this is a link through google-translate).
The pentax optio W60 is waterproof itself (4m) has a wide 28mm lens, ISO to 6400 (on a 1/2.33" 10mp sensor..) , manual focus, no image stabilization.

was wondering if anyone has seen this housing available in any other site on the web. the US version of seatool (seatoolUSA.com) only lists dSLR and video camera housings as far as i could see.

micro four thirds

2008-08-06T18:00:00.002+10:00

Excellent news !

Olympus / Panasonic announced the micro four thirds format, which is basically the four thirds format without the mirror box and the optical viewfinder. The lens mount becomes slightly smaller too, but will still accept the four thirds lenses with an adapter. New micro four thirds lenses should be more compact.

I read the press release from dpreview.com. But of course the news can be found in many many pages and blogs.

ok now, when will the first olympus micro four thirds appear on the market?

new blog on the block

2008-07-24T17:18:00.003+10:00

Bjorn has started a new blog on diving, the "Sydney Diver Daily", only not so daily in his posts i guess. There is an interesting post there about the salvo 12W LED canister light.

quick price check for dSLRs

2008-07-23T13:42:00.004+10:00

A quick price check for entry level dSLRs with a housing
(prices are in US dollars, so also in AU dollars..)

Olympus E520 in an Olympus PT-E05 housing, with the standard lens port PPOE05 :
700 + 830 + 300 = $1830
Canon 450D in Ikelite with port:
800 + 1330 + 200 = 2330
Canon 1000D has a price tag of 700USD, but not sure about a housing for it.
Nikon D60 in fantasea (fantasea housings prices include a port):
630 + 1000 = 1630
Nikon D80 in fantasea:
950 + 1100 = 2050

I believe that the olympus housing is the only one (from the short list above) that allows the camera's internal strobe to be used (for use with external strobes connected with optic cables).

creatures of bare island: pygmy lionfish

2008-07-21T16:43:00.003+10:00

We keep seeing a pygmy lionfish (possibly more than one?) at bare island. it has the strange habit of sitting inside sponges upside down, or pointing its "nose" straight down.

I was just reading this article about lionfish that threaten reefs in the Caribbean, so I remembered the lionfish photos i got from bare island, somehow!

The most recent encounter was saturday 19-Jul-2008. This time it was not hiding in the sponges as usual.

.
photos from 25-May-2008, and on 26-Apr-2008.

from 10-apr-2008, night dive:

More pics (14-Mar-2008)

I believe my first photos of this lionfish at bare island are from 30-Jan-2008.

Here are the photos that i got from different dives, side by side, oldest to most recent.

rumors of a new nikon P6000

2008-07-16T23:32:00.002+10:00

I am reading through DivePhotoGuide.com that there are rumors about a new nikon P6000.
The specs mentioned in the photo that appears on flickr, in full size, include:

28mm eq. wide lens, Raw format, 6400 ISO, nikon's VR, 2.7in screen and 13.5 mpixels on a 1/1.7 sensor.

new Canon 1000D

2008-06-11T23:00:00.002+10:00

canon 1000D announced, which is placed below 450D. most features are similar to 450D (including the live view with both phase and contrast detect auto focus) but with a smaller lcd screen, slightly slower in continuous mode, no spot metering, 7 point (instead of 9) AF, no highlight tone priority, and slightly less magnification on the viewfinder. for a detailed preview see the dpreview pages.

new pentax Optio W60

2008-05-24T22:18:00.003+10:00

a new compact camera from pentax, which is

waterproof to 3-4m (13ft) for 2h
dustproof and freezeproof to -10C (13F)
wide lens (28mm equivalent)
manual focus
1cm macro focus
9 point TTL contrast detection AF (9 point, spot, auto tracking, macro, super macro, infinity, pan, manual focus)
ISO up to 6400
High-Quality Movie mode with HD resolution up to 1280 x 720 pixels
10mp, internal optical zoom 5x
available in July 2008 for US $329.95

if only pentax would make a proper underwater housing for it. i like the idea of having (possibly as a second camera) a waterproof compact camera in a waterproof housing.

my first underwater camera was a pentax optio s30 in a pentax housing, and i was very very happy with it. especially the super macro mode. using just the camera's internal flash and super macro mode the photos (sometimes) were very good. i still cannot get such photos with my canon g7, two inon strobes, and an inon wet macro lens, after thousands of photos. some examples from my old pentax camera: one, two, three, four. a problem with my old pentax was that it was very very slow to focus and take a photo.

more info about the new pentax w60 on dcviews.com or the h2ocamera.com site.

dolphins

2008-05-24T19:40:00.003+10:00

for the first time this saturday i saw

dolphins while diving
dolphins while ... driving !

cant believe there are many other cities around the world (or any) where someone can see dolphins while driving their car on a busy road with traffic jams and all that.

we saw two (small i think) dolphins at kurnell diving the leap to the steps, close to the steps and while we were at a depth of around 10m. after the dive, and while driving back into the city over the taren point bridge we saw dolphins again in botany bay with a few boats circling them.

high ISO with red filter

2008-05-18T22:52:00.007+10:00

great visibility these days in sydney. it seems that the port jackson sharks are arriving. Here is a photo of an eastern blue devil fish we saw at shark point (sunday may 18).

i tried using high ISO with a red filter at 25-28m depth. With ISO set to Auto the speed would go down to 1/5 (shutter priority mode with speed set manually to 1/60, and aperture 2.8). i manually set the ISO to 800 to get good exposure speeds (at ISO 400 still there was not enough light). At 25-28m with ISO set at 800, i would get exposure speeds around 1/30 or 1/25 which is ok along with the image stabilization to avoid too much blur.

there is plenty of noise in the pictures. simple filters (such as the ones i use with picasa) will have trouble fixing the colors due to noise (following photos tint filter with 60-70% color preservation and the original next to it).
