These images were taken on two separate trips to the San Diego Zoo. The first 16 images were taken with the EF 75-300mm f4-5.6 IS USM. This first trip was in the afternoon on a bright and sunny day. Starting with IMG 2320, all of the remaining images were taken with Don Cooper's EF 70-200 f4L on an early morning trip to the zoo on an overcast day. Thanks Don for your hospitality and for sharing your lens. Comments and critiques welcome. ~~~ jim
