Central sharpness is outstanding, even wide open, and so it snaps into focus. My copy is in superb condition, with few signs of previous use. I bought this lens (K12 in the Vivitar 28mm Bestiary) to be used as a fast normal prime on APS-C cameras, and I am very pleased with it. Sharpness: 10 Aberrations: 8 Bokeh: 8 Handling: 9 Value: 9 Camera Used: Samsung GX20, Pentax K-x Overall, Performance is on par once stopped down but If you are buying for f2 or f2.8 use, I personally suggest to look somewhere else.Д¬orners lag far behind centre, even at f8 on an APS-C camera However, you may be satisfied if you are not too critical about the sharpness or the contrast. Note that I am comparing both the copies against some of the more reputed lenses mentioned above so my bar was already high. Unfortunately, sharpness at wide open is mediocre, there is some glow and doesn't serve the purpose. Hence, the only reason for me to get this lens was to use at wide open. Although, both had relatively weak contrast till f4, one piece was poorer than another. However, optically they were slightly different. I had two copied of this lens by some confusion, I wanted to have Kiron and komine versions each but ended up with both Kiron versions, one was like new in the box and one I purchased from the forum here.Д«oth were super clean copies, and looked identical. Sharpness: 5 Bokeh: 6 Handling: 9 Value: 7 Camera Used: k-5, k-01, nex-6, A7, A7r

Comparing the two lenses by their appearance, the front and rear elements of the K12 are wider then those of the K11, so it is not just the coating that differs.' The K11 is an exact copy of the Kiron 28mm f2.0.

Reviewer Barabas notes: 'The earlier version has a much longer focus throw (3/4 turn instead of 1/4 turn) and a rotating front. K12:- Vivitar 28MM 1:2 AUTO WIDE-ANGLE No. The nameplates are the quick means of distinguishing the variants of the kiron made f2's: There are a large number of Vivitar 28mm variants, listed in this blog.
