10 out of 10 points and recommendedExcellent sharpness from wide to narrow end of focal range. Works well with FX bodies or film. Useful focal length range. Macro a bonus with this inexpensive lens!Some barrel distortion @ 28mm, not really noticeable elsewhere. A little vignetting wide open (3.5/4.5), not terrible.
I came across this lens with the recent purchase of a used D700 (date of this review 3/14/2018). I didn't really have an inclination to buy it except I was getting rid of all my DX glass and needed a mid range zoom, and the guy selling said "Fifty bucks and I'll throw it in." For that price, I couldn't pass it up. So here we are. I recently did a birthday party shoot in near complete darkness, and the results were amazing. I shot with my D700, Phottix Mitros speedlight, and this lens. I have previously owned a 24-70VR (Yes, the $1,800.00 one.), and this one is damn close in image quality. Sharp corner to corner, focus dead on...even in near total darkness, nice contrast. Most of the shots I took were fairly large group shots, with some up to 20 people--and I noticed a small amount of distortion, but the client did not and was thrilled with the results. If you are considering spending a boatload of money on a 24-70VR, you owe it to yourself to find a good used copy of this lens...the results are not that different.reviewed March 14th, 2018 (purchased for $50)
