Does anyone have experience with this lens? I’m thinking about buying it. How does it perform with extenders?
I don’t really need it, I have the 300 2.8, 400 f4 DO, and 500 f4. I just think it might be a great lens for a walk thru the zoo, or for football while standing in the end zone. Yep, I collect lenses.
It is a BIG HEAVY lens - check the weight and size before you buy ! I saw somebody who had one - I thought it was a 600 f4 !
I have seen the Imatest numbers - they are not impressive - especially for the cost - if that matters. It does seem to get good reviews tho .....The size/weight make it impractical for use other than on a tripod !
I checked my 2013 edition of Canon "EF Lens Work III" - and it is not in there......8-(
