9 out of 10 points and recommendedGood quality overall. Light weight, easy to use.If you are used to USM lenses, this focuses less quickly and with more noise. It's better than most other non-USM's though.
Perhaps quality varies from sample to sample with this lens as it seems to others. My one seems to be a very good one. From the first time I tried this lens, I was surprised almost to the point of being shocked at how good it was compared to what I was expecting from a roughly $200 new cost lens. I've not seen the quality of this lens exceeded in any lens costing anywhere near it.reviewed November 11th, 2015 (purchased for $239)
The lens is decently sharp at 2,5 and once at 4,0, it's terrific all the way up. I have successfully used this in macro shots as well as general 50 mm use on my FF camera.
If given a choice between saving some money and the f 1.8, I'd go with this lens. If it was between this and the f 1.4, it'd depend upon my choice of low light or macro. I also think my example is better than the f 1.4 I had for a loan a while back.
Personally I'm very pleased with this lens. As my new 5d2 can shoot high ISO's well unheard of only a short time ago, the roughly 1.4 stops from here to the f 1.4 isn't relevant to my needs where the macro is of great use.
Of course, if you can have it all, then the 100 mm or 200 mm macros with the 1.2 are the way to go. For us, who are on a budget, this lens does a heck of a lot.
