I am trying to decide whether to purchase a high end P&S system for my step up from a 3 megapixel P&S I used successfully when snorkeling. Or go straight into DSLR.
P&S = Much more economical for a step-up. (New G9 or new G10 with Ikelite housing and external strobe for about $2000.) Easier to get into because I don't have to decide on a lens and purchase a port when I have no idea what lens to buy. May be able to add external lens increase wide angle view, although 28mm may be the max possible (with decent results) from either camera.
DSLR = I have 5 years experience with a Nikon D100 DSLR (6.1 megapixel) (whitewater, nature, family and landscape photography) and know the camera. Can still house it ($1100 new but have found only 1 Ikelite still sold) but what lens, port, lighting? And, I need to buy a back-up body in case the housing floods and the camera has been obsolete for years. If I house the D100, ithe system likely will be difficult to sell when I want to upgrade.
Other Nikon DSLR = D80. D200, D300. THE most expensive alternative. ($4000 new) Knowing nothing about the nuances of moving to DSLR, I have had a daunting experience trying to learn about my options, the costs and the components needed to build a system that I can grow into. Daunting AND expensive and I don't want to make a mistake for something I will use 3 weeks a year. And, something I would likely keep for years.
I really need to stop obsessing about this and JUST DO IT!
Any suggestions/enlightenment would be greatly appreciated.
Thanks,
Laura
It sounds like you have all the bases covered in what to look for (plus portability weight issue)
The Canons are nice cameras and since they both shoot RAW, with a decent recycle time, it is a plus. Take a look around and you will see some amazing results from G9s. G10s are still new and no one has taken them underwater yet. Having played with a G10 it seems to focus faster than a G9. Both will not be the same level as a dSLR in terms of shutter lag or quality, plus other things such as noise and aperture, though for the most part you will probably be shooting at ISOs underwater where the noise will not be an issue. And as to the widest WA, you have that part down also.
Of course wider WA is always cool, but 28mm on the G10 is a nice step up (have not seen actual results yet UW since the housings are not out). You may want to wait a bit as the G10s get in the field, housings should be coming in the next week and I would guess reports should come soon thereafter.
As to whether you want to pay for a dSLR for three weeks of diving it is a personal choice - I dive 3-4 weeks a year and to me I did step up to a dSLR. Depends on what you are looking for out of shooting.
I am not sure I would house the D100 at this point, unless you find a real good deal on a used housing. The Nikon D90 (newest one) is a nice camera and probably a step up or the D60. You could also look at the 40D (price dropped), 50D Xti by Canon in the same price range. It is the housing, lenese and ports where you will spend the main money - in other words (using Canon for Example) the Xti is about $750, the 40D about $850 and 50D about $1,000 or so (bodies only), while the housings for each will be all about the same price. (This is really broad brush and take a look at pricing.)
If you like you P&S and the daunting and expensive are issues (particularly based on how often you dive and what having a set-up means to you based on what you want to achieve) then the P&S may be the answer.
