M-Rokkor 28mm f/2.8 lens: White spots-- are they an issue?
I am looking for a good/inexpensive (aka value) 28mm lens for my M6 and I have noticed that the Minolta 28mm lenses go for reasonable prices considering their white spot issue.
I just checked ebay and noticed that almost every lens for sale has a case of the spots (in the $400-550 range). Do widespread spots have an impact on image quality? What should I avoid? If the spots do have an impact, to what degree does it occur? Do they spread?
