Corfield Lumax 50mm f2.8 manual focus, full frame, prime, vintage lens
Had two Periflex cameras for years and sold both bodies and one lens some time ago
Produced great results with this lovely, sharp lens on a basic L39-NEX adapter
Don't know where the original lens cap is, so comes with generic one I used
Handy and unusual, for this type lens, pre-set diaphragm ensures accurate focus prior to taking
Actuating ring is click-less, great for video
Sturdy, all metal, quality construction, German optics  

M39 screw fit mount, 28.80 mm flange distance, adapts easily to mirrorless 
Natively compatible with rangefinder type cameras though not rangefinder coupled
Smooth, hard stop infinity focusing to useful, close, unindexed 0.4m to focal plane
Focus scale marked in Feet with quaint Inf instead of the usual ∞ !
Single-coated optics - four elements, I believe?
Condition commensurate with age, some dust and small ~2mm scratch at edge of front element  
Click-less whole stop pre-set, to f22, smooth aperture ring
Clean seven blade diaphragm
Depth of field scale
Made in West Germany
Cameras, cage and adapters shown not supplied   
From pet/smoke free home
