      Performance of this popular 85mm f/1 8 Nikkor lens produce sharp and contrast images even wide open, like all fast telephoto lenses, purple fringing visible in the area out of focus highlights, only if you shoot at full aperture and crop on a scale of >100% .  With fast F1.8 maximum aperture enables greater isolation of depth of field.

           all picture taken at wide open, I always take sample pictures at the wide maximum aperture, because if you stop down to the smaller aperture certainly you will get good results.
