I am currently shopping around for a telephoto lens, and I feel rather overwelmed. I really don't want to spend a fortune on it, and $150-300 should be ok. I am not sure what qualities I need to look for, or what brand to choose. Also, I am new at photography, so I am unfamiliar with many of the terms listed under the different lenses, i.e., Sigma - AF 28-105mm f/ 2.8-4 Canon EOS. What does some of that stuff mean? Does anyone have any suggestions? I am looking for a good quality lens without breaking my wallet. I want to be able to be fairly far from the aircraft, yet still zoom in and produce excellent photos.
Please be patient with me, I am new at this!! Thanks a lot!
