Corfield Lumax 45mm f/3.5 Lens – LTM Leica Thread Mount – British Made – Rare

Description:

The Corfield Lumax 45mm f/3.5 is a vintage standard lens designed for the Corfield Periflex series, using the Leica Thread Mount (LTM) 39mm screw fitting. Manufactured in Wolverhampton, England during the 1950s, this lens reflects the British response to German optical dominance. Though it shares the same mount and flange distance as Leica, it is not rangefinder coupled, making it ideal for scale focus or adapted use on digital mirrorless systems. A rare and historically significant lens for collectors and enthusiasts of British camera engineering.

Collectors Notes:

This lens was part of Corfield’s Periflex system, which featured a unique periscopic focusing mechanism. The Lumax 45mm f/3.5 was likely produced in collaboration with German firm Enna, and later versions may share design traits with Enna lenses of the same period. It is not rangefinder coupled, but can be adapted to digital mirrorless cameras for a distinctive vintage rendering. A rare find in the UK market, especially in usable condition.
