I am a hobbyist. For many years I took incredible pictures with a Kodak Z612. Yes, it has a Schneider-Kreuznach lens, and I can adjust almost every setting on it known to DSLRs, but it's mostly a point and shoot. I decided to try a Canon T2i several years back. I only have the two lenses that came with it, an EFS 18-55 IS and an EFS 55-250 IS. I take mostly outdoor landscape shots. Many of the pictures have no depth. They are not always sharp, not like the Kodak pictures. People in the pictures don't pop out from the background. I can't catch a decent bird shot, even with shutter at 1/1000 and aperture at f8. Flowing water pictures don't have that misty quality. Since I know I am capable of taking those kinds of pictures, I'm trying to figure out if it's the lens, and if so what lens (or lenses) should I look into; if it is the camera (am I expecting too much from a consumer grade camera?); or if it is just me and the camera together that don't work. The weight isn't a problem, I know how adjust my settings for the situation, I only use the viewfinder, in burst mode I can usually get one photo that looks decent (out of 10), and sometimes the planets align correctly and I just get a great shot, but I'm not used to burning through 200 pictures to get 20 decent ones.
I know this is way too generic a question, but does anyone have any suggestions as to where I should start to figure out what is wrong with my picture taking ability and this camera?
