Originally I had hoped to post a test of the low-cost Korean 85mm f/1.4 along with my Nikkor 85mm f/1.4D review. Unfortunately, as I got deep into the testing, I discovered that my Bower 85mm sample had a clear manufacturing defect that precluded it from getting consistent or accurate exposures. Pity. Other than the fact it didn't work, the build quality seems quite good ;~). Optically, I was only able to accurately test at f/1.4, where it is slightly softer in the center and corner than all other 85mm's I've used, shows significantly more vignetting than the Nikkor that I just completed testing, but has about the same distortion numbers (i.e. nearly none). I'm not going to retest it.
