7 Artisans DJ-Optical 90mm f1.25 for L mount brand_Whitehouse Products Inc. 6 stops more light thanThe 7 Artisans DJ Optical 90mm f1. 25 is bigger and heavier than most 90mm lenses, though you might have guessed that based on the aperture. It's manual focus, with a mechanical diaphragm, and image quality is actually, surprisingly good, even wide open. I mean, obviously, depth of field is minimal, and f1. 25 is not the place to be for critical sharpness, but it's usable, and that's kind of impressive. In excellent condition, with clean glass.
