|comment:||I bought this lens on e-bay to take on safari to Tanzania and Kenya with my 5D and couldn't have made a better purchase.|
It performed really well handheld and rested on roof of landrover (took tripod but had no chance to use it). Coped extremely well with the inevitable dust and none seems to have been sucked inside the lens.
Took well over 1,000 shots. Found that I could see more through the lens than most of my companions saw through their binoculars.
I also used a 70-300mm Sigma APO lens for when on walks in bush as the big lens was rather heavy. Took a Dimage A2 as well which, with its 28-200mm fixed lens, was great for wider angle work.
On the African plains I found that an aperture of F8 worked best under most conditions. I didn't get the chance to shoot a high speed chase but had I done so I think that opening up as wide as possible would have been my best course.
While the performance is not quite upto the same standard as Minolta G series of prime lens it does come close to the pictures I have seen taken with those.
For anyone looking for a reasonable cost wildlife lens I couldn't recommend this more highly.
Now I have tested it on the A100 I am even more impressed with its performance and sharpness
