Scuba Forum / UK Scuba / December 2006Info on digital camera characteristics for scuba diving
Hy, this saturday with a friend of mine we had an immersion at Tor paterno, near Rome, It was two year that we don't have scuba diving, last time was in Sharm in 2004, Raskati and Shark & Jolanda, Now I would want to buy a digital photo camera, have you any idea of which one is the best at the moment for diving application ?? I'm interestetd also to know the following: 1) Which zoom is the best suitable for diving, 10x or there are problem wih the focus ?? 2) It is a good idea to buy a camera with high iso, maybe 1600 or 3200 to avoid usage of lamp ?? Which iso is best fitted ?? Many thanks, Antonio www.etantonio.it/en/sport/diving/ It depends on how serious you want to be. Pretty much all digital cameras will give reasonable results but to get anything even remotely "pro" looking you need an external light source. I use a compact digital (Canon IXUS400) which is fine when combined with a light source for close up work. The other thing to bear in mind is that carrying and using a camera will result in much higher air use - a general rule of thumpb is about 25% - 30% more air if you are carrying and using a camera. > The other thing to bear in mind is that carrying and using a camera > will result in much higher air use - a general rule of thumpb is about > 25% - 30% more air if you are carrying and using a camera.

Personally I tend to relax more when using a camera, and between that and the lack of finning around, air consumption goes down a fair bit... I can understand it going up if you're following a guide around and having to drag the unstreamlined bulk of a camera at the same pace as everyone else...

I suspect it depends on hat you're doing. If you go on a dive for the purposes of taking ONE shot of the little shrimp in the sponge and spend all your time waiting for the cheeky chappie to smile, your consumption will be down. If OTOH you're on your typical follow-the-leader guided dive with a compact in a housing and no external flash, your consumption will not be perceptibly different. However if you're followin the diveguide lugging a HUGE case full of Nikon D80 with a pair of vastly extended arms with large strobes on the end, you're going to use a lot of air. However, on a drift you can put your camera kit to good use as a sail . . . . Ken >>> It depends on how serious you want to be.

I'm actually looking for a small compact so I have something to jam in a pocket for dives that I can't carry my normal cameras on... I've been looking at things like the Fuji F30 as it's housing looks pretty tiny and although it can't shoot RAW, that's not too much of an issue for the intended use. <snip> >Yep, that's about it...

For a small compact I was impressed by a Sealife DC500. The owner was getting reasonable results and the camera housing was certainly tight. It was definately easier to put in a BC pocket than my DX200!

There is no such thing as a "best camera". If there was, everyone would be using it! There are many cameras which get good results, which one you go for depends on what you think is important. A good way to decide is to choose from the relatively limited range of cameras for which there is a case available. Within that, there are some choices according to make. For example, Olympus cases have lens ports which are threaded so you can very easily add accessories such as filters and wide-angle lenses. Canon OTOH does NOT have threaded ports and while you can add accessories in front of your lens, it becomes much more expensive and more difficult to organise. > I'm interestetd also to know the following: > > 1) Which zoom is the best suitable for diving, 10x or there are problem > wih the focus ?? I use an Olympus c750uz (now obsolete) which has a 10x zoom. The zoom was NOT a reason for buying this camera, and I would say that such a powerful zoom is USELESS underwater - 3x or 4x is the most you might use. There are no problems focussing. > 2) It is a good idea to buy a camera with high iso, maybe 1600 or 3200 > to avoid usage of lamp ?? Which iso is best fitted ?? The higher ISO, the more the noise (grain) on the image. The best solution, whether you want to fit one or not, is to fit an external flash. This restores the colour, and allows you to use fast shutter speeds (to freeze movement) with low ISO settings (with low grain). Ciao Ken > Hy, > this saturday with a friend of mine we had an immersion at Tor paterno, [quoted text clipped - 9 lines] > 1) Which zoom is the best suitable for diving, 10x or there are problem > wih the focus ?? It depends what sort of water you're diving in. High zoom is obviously great for getting shots of distant objects and good photos of fish without getting close enough to scare them off. But, if you're diving in low visibility water it also means there is much more dirt in the water between camera and subject which tends to ruin the photos. > 2) It is a good idea to buy a camera with high iso, maybe 1600 or 3200 > to avoid usage of lamp ?? Which iso is best fitted ?? High ISO generally means reduced colour quality. Generally, if you really want good photos underwater you have to bring your own light. What about this camera ??? panasonic DMC-TZ1 http://www.panasonic.it/Products_Info.asp?M=3353|662|654|652|4|1 it is well suited for underwater photography ???
