p.1 #6 · p.1 #6 · 85mm and 135mm's as alternative to 70-200? (Basketball/editorial perspective) | |
Short answer: stick with the zoom unless you can also justify having multiple bodies. No sport is going to pause while you swap lenses.
If for whatever reason you do go ahead with the primes, the 85mm f/1.4 is probably going to be your best bet as far as focus and optical quality goes. (Whether the focal length is suitable is something only you can know, really; we don't know exactly where you'll be sat.) It's a really great technical lens in every regard and is one of the few 85s which has ever actually impressed me. I'm just not entirely convinced that an 85 will be suitable for your purposes.
Forget the 85m f/1.8; the similar 100mm f/2 focuses much better, is actually a little brighter, and has better technical optical quality. (In fact, the 100 was the original lens, and then Canon clumsily modified it to turn it into the 85; every part of it is optimised for the 100, not the 85.) It actually is the fastest-focusing EF lens Canon ever made, at least when you put it on the bodies which can deliver full voltage. (Yes, faster than any of the Ls; it doesn't have to move much glass, after all.) Though it still has a lot of fringing and generally I wouldn't recommend it for professional sports work. Great portrait lens, though.
The 135mm f/2 focuses faster than the 85mm f/1.4, but not by much, and the lack of IS means the focus system has a tougher time being accurate, especially as light levels drop. Great lens and can be a great sports lens, but there's a good reason why most people use a 70-200 f/2.8 instead.
So, again, stick with the zoom.
