Jessop MC 2X Teleconverter – Konica AR Mount – Very Good Condition

Overview

A Jessop MC 2X Teleconverter in Konica AR mount, designed to double the focal length of compatible Konica AR lenses while maintaining a compact, lightweight setup. Jessop’s MC‑series converters were popular third‑party accessories during the manual‑focus era, offering dependable optical performance and solid mechanical construction at an accessible price point.

This example is in Very Good condition, fully tested on a Konica AR body and ready for use.

Key Features

• 2× magnification for extended telephoto reach
• Konica AR mount – compatible with all Konica Autoreflex and FS‑series bodies
• Multi‑coated optics for improved contrast
• Solid metal construction typical of Jessop’s MC accessory line
• Maintains aperture coupling for correct metering on AR‑mount cameras
• Compact, lightweight addition to any Konica film kit

Condition

Very Good Condition

• Light cosmetic wear consistent with normal use
• Bayonet mounts clean, secure, and lock positively
• Optics show light internal dust only (typical for age; no practical impact)

• Aperture coupling mechanism operates smoothly
• Fully tested on a Konica AR body and functioning correctly

Compatibility

Fully compatible with:

• Konica AR‑mount 35mm SLR cameras (Autoreflex T, TC, T3, T4, T5, FS‑1, FT‑1, etc.)
• Konica Hexanon and Hexar AR lenses
• Third‑party AR‑mount lenses from Tokina, Vivitar, Soligor, Hoya, etc.

• Front and rear caps 

Collector Notes

Konica AR‑mount accessories are increasingly sought after due to the strong reputation of Hexanon lenses and the relative scarcity of later AR‑mount equipment. Jessop’s MC‑series converters remain a practical and affordable way to explore longer focal lengths on classic Konica film bodies, and well‑kept examples like this are becoming harder to source.
