Pros:	Good value for money
Cons:	A little dark at max magnification for my use

The appearance is professional and very well cured for.
I bought it for my Canon Eos 350d and i am pleased with how they work together.
Unfortunatly it is without OS system (Optical stabilizzer) and i suffer a little for this, especially when i work at 400 mm.
I noticed a marked improvement of pictures if you shoot at about 380 mm, so if you need 400mm and you have a 10 mpx and over camera, you can shooting a less magnification and cropping in pp. In my opinion the result is better!
From 135 up to 300 photos are very sharpened and if you close at F8/F9 are better and better.
The Af is a little slowly when light condition are poor and sometimes i work better with Mf.
It weighs 1,2 kg so at 300 - 400 mm if you dont have a very good tripod, photos are irremedibly bad.
