AI-assisted summary
Description from the seller
Beautiful, early serial number (#13300018) RE. Auto-Topcor 85mm f/1.8 in excellent working condition.
According to collector research, the known serial number range for this model spans 1330001 to 1330788, with approximately 1,000 units produced total - making this the 18th documented example. This lens is considered one of the finest and rarest in the Topcon lineup, based on a classic Ultron-style optical design and renowned for its sharpness and beautiful bokeh rendering.
COSMETIC ELEMENTS: 4.5/5
- Clear and clean markings on the front ring, aperture ring, lens barrel.
- Minimal wear on some parts of the aperture ring.
- Focus rubber ring in very good condition, clean with negligible signs of use.
- Overall the lens is well preserved and shows minimal use.
MECHANICAL ELEMENTS: 5/5
- Aperture ring is smooth and clicky in classic RE.Auto-Topcor fashion.
- Blades free of grease, no deformation and moving freely.
- Focus ring is smooth and linear (no bump, no stoppage etc).
OPTICAL ELEMENTS: 4/5
- Front and back glass elements show no fungus or haze.
- Minimal dust inclusion.
- Coating of the front element shows a slight blemish 2mm in size. Not likely to cause issues (contrast, flaring), though visible to the naked eye at an angle. Doesn't seem to appear in bokeh balls either.
- Inspection under strong and direct LED light reveals superficial scratches and cleaning marks on the first element. Hardly noticeable under normal daylight and no adverse effect on image quality (tested at all apertures, too superficial/sparse and well within MFD).
Original rear cap included + generic screw-in front cap + original leather case.
FOCAL LENGTH: 85mm
APERTURE: f/1.8 to f/22 (half-clicks)
NUMBER OF BLADES: 6
OPTICAL DESIGN: 7 elements in 5 groups, single-coated (Ultron design)
MFD: 0.9m (may be reduced with the use of an helicoïd adapter)
FILTER THREAD: Ø62mm
MOUNT: Topcon/Exakta/Beseller
ADAPTABILITY: full-frame mirrorless, APS-C, MFT, etc. via adapter
S/N: 13300018 (1970)
FLANGE DISTANCE: 44.7mm
WEIGHT: ~480g
CONSTRUCTION: All metal barrel, rubberized grip.
Worldwide tracked delivery with FedEx.
