Good thread, BigMike.
I'm a very happy owner of a Sony DSC-F707, an exceptional camera with which I've taken great pictures. But last year, while on a photography trip to Yellowstone National Park, I found that sneaking up on wild animals to get a shot was just plain stupid. This was NOT a good idea:
As you can see, the shot is a bit soft. I was standing in a marsh, my camera on a tripod because of the low light (it was around 7AM), with the road about 200 - 300 yards behind me. It was dumb, but wow, that was a pretty moose. I also missed some nice shots of hawks, turkey vultures, and other assorted animals because I couldn't get close enough without getting eaten or gored. I also want to get into candid shots of people, and in NYC I'll need a nice loooonnnggg lens reach to do that...
I also couldn't live with the Sony's limited not-so-wide angle. I needed wider for landscapes. I ran into this limitation with my fall foliage shots as well as NYC skyline shots. I need the wide angle, and I'm considering the Sigma 12-24 for that.
I am a firm believer that one can take phenomenal, professional-quality shots using a digicam like the Sony. Many great photographers have proven it. I will continue to use my Sony for certain situations, but the overall flexibility and reach of a dSLR are what I need for this stage of my photography.
In the end, however, it is the photographer, not the equipment that takes the nice picture. I also believe that it's the camera lens system I'm buying into; the body can be upgraded, but the glass remains. I do this all as a hobby, but I do donate my prints to charity events (charity auctions, etc.), and I sell prints to those who ask for it.
