Review

I bought this lens in April 2006 for R105,00 on www.bidorbuy.co.za. It has a largish chip on the front element, which does not affect picture quality. As I primarily use screw-mount lenses on EOS bodies, this lens works great due to its pre-set diaphragm. A must for portraits, where auto-focus is unnecessary.

Recommended: Yes
