Summary: This is a super sharp lens that holds up very well to high resolution sensors. Sharpness is what I've come to expect from macro primes with reasonable specs - this lens, my Tokina 100mm f/2.8 macro and my Nikkor 55mm f/2.8 macro are my three sharpest lenses.
i don't use the auto features much because I like to control all the camera and lens operations manually

Summary: I purchased this lens a couple of years back. I have shot extensively with both the prime and macro features. Much of my work has involved shooting two dimensional artwork and various macro subjects.
Summary: This lens is extremely sharp wide open, AF is precise and fast (faster than the Nikon 35mm f1.8) macro feature is icing on the cake. Build quality is very high. The only draw back (not really a design flaw more as a result of the 35mm designation).
Summary: I selected this lens over Nikon 1.8G after reading so many positive reviews about its performance. It turns out, it did not disappoint; this lens is the sharpest lens in my collections besides may Nikon 55mm 1.8G. Construction is very solid and the bokeh is pleasing to the eyes.
Summary: Warehouse deal @ $202 (warehouse inspected, returned item perhaps) is same price as Nikon 35mm 1.8G. Chosen this over Nikon just because I like Tokina quality. NO AF Motor = I do not mind screw drive for long term reliability than electronics. Macro lens that Aperture dropped when near focus.
Summary: This lens has the same optical design as the $700 "Pentax 35mm Limited". I've shot both, and they're exactly the same. Do not hesitate to buy this lens - excellent across the frame even at f2.8.
