canon 450D/XSi preview

dpreview.com has published a part of its canon 450D/XSi hands-on preview. it is about half the usual review, the full review will follow within two weeks according to the website.

some features that look interesting:

  • live view with edge detection auto focus
  • highlight tone priority- according to dpreview, in this mode canon should capture more information in the bright areas of the image at the risk of more noise in the shadows
  • better (or more) noise reduction in high iso
  • "my menu"
  • displaying the iso in the viewfinder

creatures of bare island: striated frogfish

interesting creatures from bare island:
i believe this is a striated frogfish (Antennarius striatus), a kind of anglerfish.

canon 450D / XSi dSLR

the new canon 450D is available in most places for around 900USD with the kit lens (IS 18-55).
No housing for it yet. Just to get an idea i looked through digideep.com, to see how long it took for the underwater housings to be available after the camera hit the market. i only looked at fantasea and ikelite to get an idea.

so fantasea is a bit slow with its housings, is it?

too bad, i would choose fantasea over ikelite since the price is better, and also some of their housings are slightly more compact. but if they take 6-12 months to get the housing out, well... that's not good, is it?

Olympus E-420: no olympus housing for it?

here is a thread from wetpixel.com on the subject. PT-E03 (the housing for E410) has been discontinued and olympus has not announced any plans to build a housing for E420.

Olympus waterproof compact cameras

Diving without a camera feels like sort of cheating. so easy to swim, no heavy camera rig with all the strobes lenses arms etc making you use up lots more air. it's just too easy.

So sometimes one might want to dive "without a camera". Which of course means diving with a smaller camera rig-- diving with no camera at all (really no camera) is impossible, lets face it. It makes no sense whatsoever.

I've been looking at the olympus waterproof cameras. Compact thin cameras, probably good to use on land, when traveling, a small camera that is easy to keep in a pocket. Also, when using them in a housing during diving, a leak is probably not a big problem since the camera itself is waterproof.

The images on this post are stolen from the olympus australia webpages (and link to them). There are several models, in, lets say, two categories: the ones waterproof to 3m and the ones waterproof to 10m. the newest model is the 1030SW (Shockproof-Waterproof).

see the olympus australia website for more info and more pictures or dpreview's page.

Olympus 1030SW, 10mpixels, wide 28-102mm equiv lens, 1/2.33" Type CCD, waterproof to 10m, shockproof for drops from up to 2m, crushproof for up to 100kg, freezeproof down to -10C. According to the olympus australia webpages, the camera has a 1fps for flash sequence shooting, or 6.9fps flash sequence shooting at 3MP.

Bad things about it: no aperture/shutter priority, no manual controls, no image stabilization. Only up to 10sec high quality (VGA) video recording. And also those stupid useless xD cards. But fortunately there seems to be a micro-SD to xD adapter.

Other models include 850SW and previous models 770 790, 795 etc.

Olympus makes proper underwater (40m) housings for the SW series. the 1030SW goes with the PT-043 housing, waterproof to 40m, with a threaded lens fitting (52mm) that can take wide angle, fisheye and closeup wet lenses, as well as red/color correction filters. A step-up ring (52 to 67mm) is available (by olympus and others).
The 1030SW is listed for 400USD, and the housing around 220USD (for the housing see for example from videodirect.com). Previous models are now much cheaper but the housings are about the same price as far as i can see. 790SW or 770SW are about 250USD.

Reading the reviews for SW series olympus cameras from dpreview and other websites it seems that the actual image performance of the camera is not that great, however the features and the underwater-friendly attitude of olympus make these cameras very attractive.

The newest model 1030SW is the best choice because of its wide 28mm equiv lens. The biggest problem is the lack of aperture/shutter priority and manual modes.

Blue ringed octapus and a lionfish

During a night dive at bare island last night we saw a blue ringed octapus sitting on top of some sponges. Unfortunately when i stuck my camera to its face it decided to hide and i couldnt get any decent photos of it.



abit further down there was a juvenile lionfish. It was a bit cold i thought, and I guess so did the lionfish that was hugging a sponge very tightly...



I was using my new Inon UCL-165 macro lens and i believe i had some minor problems focusing. mostly i need to get used to the lens i guess but i sort of thought the camera was slightly slower in focusing when my focus light was not aimed properly for example. but still i am quite happy with the new macro capabilities...
