"Very sharp stopped down 2/3 to 1 stop Excellent finition"
Pros
Excellent resolution especially at the extremes of 10 and 20mm
Cons
Some distortion at 10 to 12 mm. But as with all super wide angle lenses quite acceptable

I purchased this lens about a month and a half ago and have already used it for an eight page fashion story for LINEA Magazine. I am impressed with how sharp it is at the two extremes i.e. at 10 and 20 mm. I love how wide it goes. It reminds me of the Canon 16-35 full frame lens. It is extremely sharp stopped down 2/3 rds to 1 stop at all apertures. The construction is robust as is the finition. Purchase an excellent filter for this lens and keep it clean. Dust will show up in the photos if stopped down to F22. I use a Hoya Pro1 UV that stays on the lens at all times.
Don't hesitate to purchase this lens. It is a keeper. It can be used on the Canon D1 with vignetting at 11 mm and full frame with vignetting at around 12.5 to 13mm. Not bad at all.
One more thing. Being of EX quality, I would go as far as to say that it is comparable to "L" glass.
