hello everyone. i'm new here and know very very little about photography so any help will be greatly appreciated. i am a helicopter flight instructor and while doing the instructing i also take aerial pics of farmers planting and harvesting their crops. i started off with a nice canon S3 IS that took really nice pics. so i then decided to go the way of the SLR and bought myself a 60d (body only). i noticed that 60d took really nice photos as well but i wasn't as impressed with the quality or the clarity as i was with the S3. i am using just a 18-55 efs that came with a "eos rebel xt" kit that my wife had bought a few years earlier. i've had people tell me that i need to get a L-series lens and then others tell me that the 60d is not good enough of a camera to get everything out of the L-series lens that it offers...plus i don't want to spend that much money. i normally take my photos anywhere from 100-500 above the ground and constanlly moving. i'm pretty sure i need an IS lens since i'm in a helicopter but i need someone to guide me in the right direction...PLEASE
another thing is when in video mode on the 60d i notice that during filming and playback that it is really bright and sometimes so bright that you can't see the images that have been filmed. and this isn't just when filming from the air but also when on the ground...mainly outside. thank you in advance for ur recommendations.
