Hi, I live in central florida around the orlando area and Have been diving for about 2 years now and I went on my last dive with one of those cheap 30 dollar underwater cameras that didn't even make it past 5 ft. until it was full of sea water. I don't know much about underwater cameras. I want to find a camera that is at least 10 mega pixles and can be used for everyday shots that can fit in my cargo pants pocket.
and when i want to go diving can be put in a case to use for that. my budget for the camera and case is about 700 dollars unless there is a camera that is a little more money but gets me alot more quality then i would spend 800 on the setup.
so does anyone have any suggestions on what models to look at. everytime I go into a store I get confused on what to buy
You are kinda entering the danger area by asking the "if i had a bigger budget" question as then the next question in reply would be "well, how much bigger?" Personally i would say if you stick to your original budget your best bet is the canon G10 or maybe even the G11 that is just coming out though i dont know what that is like. I have used the G10 for a while and you get some really great images from it and importantly you are able to shoot in RAW so you get all of those benefits for post processing.
Like most of the other posts say, i would also think your next step after that would to get yourself a strobe or even two. It is worth paying more and getting better strobes as they can be taken with you as/when you choose to upgrade to a dSLR system.
In terms of what camera should you go for if you want slightly better than the G10/11. Well, thats a debate that can go on for ever and i am sure that soon there will be people shouting for Canon and others for Nikon (and maybe even a few others!) but one thing just to point out is that as you go up the line of cameras the cost of the housings also go up too. For example, with Aquatica which personally i think are making some great housings at the moment, a lot better the ikelite and also depth rated to 90m (i tech dive so for me this makes a big difference as you can get a spring upgrade to extend the depth rating for them to 130m) the housing for the Nikon D90 is around $1800 but for the top end nikons the housings are up to $4000, and the same for the canon sides and then after this you have to add the costs of the ports etc.etc. So just remember that if you decide to up the cost on one end it can very very rapidly bring the over all cost shooting skywards.
I would say the 450 is a good all rounder, but so too is the Nikon D90, after that, perhaps the Canon 50D then the 7D looks great and personally i have the 5D MkII which i think is an amazing camera (but i would).
Unless you wanna make a big commitment i would say the G10/11 is your best bet then say opt for getting a strobe or two first. If you wanna go further, well, thats a whole other debate... and a big and never ending one which is always only ever decided by personal preference.
Anyways, best of luck and let us know what you decide!
