I was talking with a fellow T2i owner over on my Facebook page and she was wondering which lens is best for shooting at the zoo and an indoor aquarium. I thought it would be beneficial to share our conversation with all of you...
Diadra's Question: I just bought the T2i and it is my 1st DSLR. I have the standard kit lens and also a 80-200mm f/4.5-5.6. I have found that I like the 80-200mm much better for taking action shots of my 3 kids. We are planning on visiting the zoo, aquarium, and a few other places this week. I don't want to chance not getting good photos because I am trying to figure out which lens I should be using. I have read where you recommend the 50mm alot. Would this be a good idea as well for shooting at the aquarium?
Moose's Answer: The 80-200mm f/4-5.6 is an older, budget telephoto lens. In my experience with the lens, I found it to be a little slow to focus and not very sharp. The aperture range also presents a problem when shooting in low light situations (indoor aquarium).
To be honest, the 55-250mm f/4-5.6 might be the better choice. It's faster to focus and sharper than the 80-200mm lens. The 55-250mm zoom range would also give you a wider and longer zoom range, which is perfect for shots at zoos and aquariums. You'll still run into some low light issues due to the f/4-5.6 aperture range, however, the lens does come equipped with image stabilization which will help reduce image blur...as long as the subject (fish or animal) isn't moving too much.
The 50mm f/1.8 is a great low light shooter, due to it's "bright" f/1.8 aperture. However, it's a prime lens which means you can't zoom in or out. When shooting in small spaces, you'll find it difficult to frame your shot...especially if there's no room to backup.
