I have a Canon 70-200. Should I get F4 IS or F2.8 Non-IS?
If you could pick one to own (since their prices are about the same), which one would it be? I've talked to other photographers, and have gotten a 50/50 response. Their defenses below.
F4 IS: IS is super helpful at 200mm, lighter, many claim it's sharper.
F2.8 Non-IS: Faster lens, 77mm filter, better bokeh.
Yeah yeah, I know there's a 70-200 F2.8 IS version, but I can't really afford dropping $2300+ on a lens right now...
I plan on (eventually) buying either the F4 IS or the 2.8 non. I'd mostly use it for taking pictures of my fiancee riding/jumping her horse at dressage events, while also using it for wildlife, cars at racetracks, and candid portraits.
Your choice with reasons and/or voices of people who own either (with likes/dislikes of the lens) is greatly appreciated!
