Very good picture quality
Lowest price in this range vs other brands
Sharp, very clear picture for Macro and for people
缺點:
Noisy
Sometimes cannot focus if the light source is not strong enough
Extending in too long, so that the focus will take time
評價:
I read www.photozone.de and other web-site before select this lens vs Canon 100 mm & other like Sigma and Tokina. All of the comments on this lens are highly recommended. I cannot believe until I own it. It gives a very solid picture.
