Now that I'm seeing that most of what I wanted in a camera could have been found in digital as well as the SLR I'm considering possibly trading up...go digital.
Storage space seems to be the major drawback. How do you all handle it? You can get a Smart Media Card up to 128mb, but if you are shooting 1024x768 .tif pics that's going to eat what, maybe 1.5 - 2mb per pic? or more? And you will probably want to shoot higher res than that just so you have room to crop in the touch-up process once you get back to your computer. If you're going for an extended shoot you WILL have to have some way of getting those pics off the Smart card. What if you don't have a laptop?
Example: Last summer me & my SLR went on vacation, away from home & computer, and I shot around 200 (maybe more) pics both aviation & non-aviation. If I had digital, what would I have done? I might have needed 3 128mb cards and that would not be economically feasible. I think what would be best is to have some way to transfer them & burn a CD-RW or two and then worry about touch-up & deleting bad ones when I get home.
Also, battery power. How long do the batteries last?
How many megapixels should I look for? some cameras are 1.2 and i have seen some 5.0 megapixels. Do you really need the high end ones to get a sharp picture that would be acceptable here?
Is the olympus C-2100 a good choice for aviation shooting? It is a 2.1megapixel and 10x OPTICAL zoom.
