firstly what is it for! which lens's are actually talking about (f-stop ect ect)


for me.Missed the reference to badminton hereBoth leses are excellent primes as well tho.
Fair point but who doesn't like seeing shots taken with a lens they are thinking of buying. I'd have put some %100 crops up (which I always find way more useful personally) but as I'm at work I used what I have available to me here and now.I think we could show him picture after picture from both lenses but seeing as they have all been sharpened in post-processing they are of little value.
The only valuable comments must be from people who have, or have used, both lenses.
