New to DSLR photography. Just got the camera last Friday. Many years ago I used to shoot 35mm film on a Rebel G. I decided it was time to get back into it and relearn everything I forgot. I hoping the problem in these pictures is me doing something wrong that I can fix as opposed to a lens problem.
With these shots I was showing my 6 year old daughter why I bought 2 lenses, since she asked. These were intended solely to show her how we can get better pictures at the zoo now, and not intended to be "keepers".
#1 is taken with the kit 18-55IS, and #2 is with the 55-250IS, both on the XSi/450D, no filters used. Out of 30 shots I got 4 or 5 that had this kind of problem. Full automatic mode, no real setup. What is causing the horizontal break in the picture? Do I have a problem with the lenses or the user? I'm OK with either answer, I just want to fix the problem.
