Depends...do you need a 200mm lens?
I don't need it, but will use it plenty if I have it. I currently have 28 1.8, 50 1.4, 85 1.8. The 200L 2.8 will fit nicely. It gives me good range relative to what I have.
Absolutely, take a punt, brilliant lens.
My first L and one of only two lenses I wish I'd never sold.
I could get good track day, speedway and jetski shots with this on an old xti.
Nicely built, compsct, light, fast, exceptionslly fast focusing with af liniter on.
Works a dream on centre spot af combined with af.
You'll find it a revelation how you'll find zoom rings a distraction after shooting on this lens.
Track BAM BAM BAM BAM BAM as fast as you can, track, track BAM BAM BAM
If I didn't need a zoom for video I'd never have sold mine.
Ask me nice and I'll post some results.
I would tell anybody to try one of these lenses. I think at one point only the 135 f2 tested sharper, and by a baw-hair.
Get the tripod ring and it handles pans and tilts like its part of you.
I like it.
I would love to see some (great) shots captured with 200L 2.8.
