Anyone used / got one of these?

Thinking of getting one, wondering if it could cope without shed loads of light? (My 28-200mm can't :thinking: )

It will need lots of light, well at least a fair bit!

I've got one and it's not bad. Looking at replacing it though after seeing Joe's picture of the Sigma 120-300 f2.8 :thumbs:

The problem with the 135-400 is the focussing speed. It is very noisy and if you just stray off target, it feels like half an hour before it's back in focus.

Wasn't too bad at Fairford last year but that was in lots of sunshine with blue skies.
