Several years have passed since I went to really nice zoo. This time I go with photography in mind. I should learn something from the adventure and trials of photography. This is the plan: 2 days to see the zoo. First day I plan to take my 18-130mm lens(27-195mm equivalent in 35mm). If it looks like a longer lens is needed, the second day I will be carrying along the heavy full frame 100-300mm with a monopod. Does that sound like a plan? I think so...we will see. I am not totally used to the longer lens and have difficulty with steadiness in offhand shots..practice, practice. So, the monopod will be part of it. For me, this will be a chance to learn more about my photo abilities with good subjects seen without stalking! : ) Any advice from "seasoned" zoo-photogs is appreciated. TomDart.
