Lumax 50mm f1.9. Made by the British company Corfield. This is the standard lens for the Periflex SLR, which uses a periscope-style viewfinder (!!). While it’s not rangefinder-coupled, it features a Leica L mount, and the flange distance is identical to that of Leica. By using an L/M adapter, you can also use it on Leica M mount cameras.
The lens has a 4-group, 5-element design. It was manufactured in West Germany under an OEM arrangement, licensed by the British company Wray. It’s likely produced by Enna. It’s said to share the same Unilite-type design as the Unilite 50mm f2, a lens made for the Wrayflex, another quirky British camera known for its challenging focusing (laugh), alongside the Periflex. This design is similar to the Biometar and Xenotar types.
The filter size is 52mm. Feet scale. The minimum focusing distance is approximately 31cm from the front of the lens. Thanks to its aluminum barrel, despite its f1.9 brightness, it weighs just 183 grams.
The lens barrel shows signs of wear, such as scratches and paint loss, but there are no notable dents or deep scratches.
It underwent a complete overhaul, including focus adjustment, in 2024. Thanks to meticulous servicing, the aperture and helicoid operate very smoothly.
The front element has numerous shallow cleaning marks. While these might impact performance under strong lighting conditions, test shots surprisingly showed minimal flare and a subdued image quality.
Sample images are available in the test gallery. We hope you find them helpful.
