*zoom ring could be bigger
*wide open at zoom extremeson lens one were disappointing (returned lens) 2nd copy better
comment:The build quality of this lens is quite good. The first copy, however, had disappointing IQ at the lens extremes, poorer than what I expected based upon sample images on Dyxum. I suspect that this copy had been returned to the vendor before, it was the last on the shelf. I returned this lens for exchange, and am hoping that the next copy will be better.

Update: I received another copy of this lens about a month ago, and am very happy. It is MUCH sharper at the extremes than my previous copy. Basically, at f2.8 at all focal lengths the iq is entirely usable, and at 5.6 and smaller tha images are quite contrasty and sharp. While at the extremes the images are not as good as in the middle, they don't fall off much, and are way better than my last copy.

Two quick notes, the original copy was very sharp between 30 and 50 at any aperture, but deteriorated rapidly at the extremes. Also, flare problems exist in that the image gets milky, the hood helps.
