I am looking to purchase a new or used Canon Telephoto zoom and was hoping I could get a recoimmnedation on best bang for the buck. I can't really justiffy the expense for an L lens as I want to keep the cost under $300. What Canon (metal mount) tele-zoom (70 - 300mm range )would you recommend? I want something that can take sharp bird and wildlife pictures at its max focal length. I am currently using a crop-sensor camera, the Canon 30D.
I tried the EFS 55-250 STM and was impressed with its sharpness and contrast. When taking pictures of wildlife it was great...very sharp but when I took pictures of geometric shapes, cars, buildings, planes....it seemed a little off. Maybe too much barrel distortion? It reminded me of a high-quality lens you migh find on a non-detachable lens camera...such as the Sureshot.
