Summary: I'm not a pro photographer,but i bought this lens based on the reviews from the professional sites,all what is said about it is true, it is sharp and crisp in most cases and focal lengths,and thefocal length is handy in most situations, i'm waiting to test- it in a real field outdoors ;)
Excerpt: I bought this lens for my Alaska Trip, the advantage of this lens over 12-24 mm is that it provides extra 4 mm which can sometimes come handy. It is very sharp and auto focus also work great with Nikon d7200. I am loving it so far.
Pros: Consistent Output, Fast / accurate auto-focus
Excerpt: This lens was purchased for landscape work and the first images are absolutely stunning! I shoot with an APS-C sensor and sharpness across the frame is great--really great. Even shooting with the sun peaking through in some frames, I see little to no flaring.
Pros: Breat Built Quality, Fast / accurate auto-focus, Image quality
Summary: Nice overall results. I went with this one after reading reviews and specs on Nikon and other Tokina options (11-16mm). I chose the 12-28mm Tokina because it offers a bit more possibilities and versatility (28mm side) than the 11-16 option.
