Excerpt: I was worried when purchasing this lens that the manual focus would be an issue. It is not. Like others say it's smooth and the perfect tension. I can quickly focus the lens for "action" shots. Granted not in an AI servo way but things stationary moving is no problem.
Gray Market Item, Manufacturer's Warranty Will Not Work

Summary: It's a good price, but this is a gray market item. The language of the warranty, instruction manual, and all accomanying literature was in an Asian language, I believe Japanese. If I find redeemable qualities or service, I will consider changing my review.
Excerpt: I agree with others about the lack of sharpness wide open. I find that after testing this lens it starts to get very sharp around f/2.8. I use it for landscapes and food photography, so having a lens that's sharp at f/2.8 is not a problem for me.
Pros: Durable, Nice Bokeh, Rugged, Strong Construction
Summary: I've used a Zeiss Planar T lens before on a 500 CM Hasselblad camera and I loved it. So I had expectations when I bought this lens for my DSLR but they were blown away. I'm a professional photographer and I just shot a series of portraits with this lens and I have to say it just upgraded my Canon...
Summary: I compared this 50mm with Canon and Sigma. The Sigma macro at normal distances was tack sharp. The Canon was acceptable within a narrower f stop range. This Zeiss had bad chromatics from wide open to a two stops down. It was only sharp within a narrow f stop range.
