55mm · f/1.7
The Auto Revuenon 55mm f/1.7 is a vintage prime lens known for its pleasing color rendition, but it suffers from significant chromatic aberration and poor sharpness at wide apertures, especially at f/1.7. Stopping down to around f/5 improves sharpness considerably. Build and handling are typical for a manual lens of its era. It is best suited for photographers seeking a cheap vintage look who are willing to stop down and correct aberrations in post.
