Sold!
$175 including shipping if purchased here directly.
Serial No. 7500296 For sale is the legendary Konica 57mm f/1.2, the crown jewel of the Hexanon AR line. This lens is famous for its incredible light-gathering capabilities and its distinct, painterly rendering. Whether you are a Konica collector or a mirrorless shooter looking for the ultimate “dreamy” wide-open look, this is a centerpiece lens.
Lens Highlights:
- Ultra-Fast f/1.2 Aperture: One of the fastest vintage lenses ever produced, offering razor-thin depth of field.
- Massive Glass Elements: Features a huge rear element that sits nearly flush with the mount—a marvel of 1970s optical engineering.
- Character: Known for a unique glow at f/1.2 that sharpens up beautifully by f/2.0.
Condition Report:
- Optics: Glass is clear of fungus or haze. There is some internal dust present, typical for a vintage lens of this age, which does not affect image quality. See photos.
- Mechanics: Focus and aperture rings are fully functional. The focus is looser than my typical lenses but within spec.
- Cosmetics: Overall “okay” vintage condition. Please note: There is a small dent on the filter ring (see photos). It does not affect the glass, but may require care if mounting threaded filters.
- Serial Number: 7500296
Compatibility:
Natively fits Konica AR mount cameras (Autoreflex series). Easily adapted to modern mirrorless systems (Sony E, Fuji X, Nikon Z, etc.) with a simple AR adapter.
