Cannon Powershot D30 -- Been waiting 25 Years for this!!!
5 months ago

Finally, a caseless underwater camera that I can take on all my dives - soooo excited!!  Going diving in 2 weeks -- wish I could get my hands on one today!

Would have liked to try out the previous D20 - but 33 feet (why cannon -- so random)  Dives are usually 45 and 85 ===>  33' just doesn't cut it.

Anyone else feel the same??

You could check out the Olympus TG2 and the Pentax WG series as well, they're both considered pretty decent tough compacts, and they're rated to 45 feet. I haven't heard as many good things about the Nikon version but that goes to 60 feet.

At 33ft the pressure is about 29PSI.  At 85ft that increases to about 52PSI.  The challenges of designing a camera to withstand the latter are considerable and the resulting device and its seals would have to be considerably strengthened and as a result be heavier and more expensive.  This perhaps helps explain why serious underwater photography is usually done with specialist housings.

I own the Nikon AW110.  I compared it to the Olympus TG2 and found that the Nikon did a better job of handling noise reduction.  It seems that all of these 'tough' waterproof cameras over-process for noise, and wind up with one degree or another of the 'impressionist' look when pixel-peeping.  I've only had the Nikon on 1 vacation, but it did a pretty good job - focused quickly and did a good job of getting the white balance right.  It also took very good videos, which is new to me as it's the 1st camera I've owned with video capability.

I had been using the G10 in it's UW case until now.  It did a great job, but the bulk took up a lot of space in my carry-on luggage.

Hopefully all of the manufacturers will improve their quality and features soon...

You should look at this thread before you buy that "Cannon".

You're getting your sheets(Cannon) confused with your cameras (Canon).

TG-2's lens opens up to f:2.0 at the wide end.  That's two whole stops more than with AW110's f:3.9.  The scene where TG-2 would use a comfortable ISO 200, AW110 would require ISO 800.

AW110's noise reduction would have to be remarkably better to overcome the difference in lens speed.

I'm sure that's definitely true in low light situations, where no doubt the Oly would shine.  I will only be using the camera in bright daylight situations (mainly snorkeling/kayaking), which is where and how I compared the 2, and Nikon edged out the Oly in maintaining better detail.  I will say I liked the Olympus' layout more.  I believe most of the tough waterproofs will give very similar results overall.

That was the big advantage of the TG-1 for me - the expanded "comfort envelope".  It actually has issues in direct sunlight (the camera enables the 3-stop ND filter when it could've set faster exposure instead, so the shutter speed drops unexpectedly).  But in less-than-perfect light it's head and shoulders above the rest.

I believe most of the tough waterproofs will give very similar results overall.

Agreed. My usual recommendation about the "toughcams" is to avoid them at all costs.  They are very specialized and make a lot of compromises.  But for some situations - like action sports - that's the only way to take any picture at all.

In diving, 33 ft would be 1 additional atmosphere of pressure. At sea level you are at 1 atmosphere, at 33 feet 2 atmosphere. If the D30 can do 82 ft that would be a great diving vacation camera.

I have been diving and taking photos for 20+ years and rarely  need to go deeper than 70 feet, unless looking for some thing specific. I think the early waterproof cameras were for snorkeling, but the D30 shows promise as a dive camera.

If Nikon ,with their Nikonos rangefinder camera could do 50 meters of depth, 40 years ago, certainly the technology was there to copy.

It's a question of cost rather than technology. The technology employed in the Nikonos of die cast sections and air tight seals to enable it to achieve those depths was not particularly advanced but the cost of building such a device was high and without regular maintenance they would often leak.  A digital underwater camera and housing can be obtained for little more than the typical cost of servicing a Nikonos V.
