Why rehouse a vintage lens?  The rehousing improves optical alignment nearly impossible to achieve in many original, vintage housings. This centering of the optics allows for a higher and more symmetrical resolution across the image.  The rehoused lenses also no longer bind up when adding a clip on mattebox and no longer telescope when changing focus.  Additional improvements include a non-linear cam focus system, evenly distributing focus marks and giving greater accuracy for focus pulling at longer distances. CSLA is home to a wide selection of both vintage and modern optics.  Expertly evaluated and maintained by our in-house tech team. 1 - TLS Zeiss Super Speed MKII Set 2 - Super Speed image utilizing a wormhole filter (@skylerbocciolatt) 3- TLS Kowa Spherical Set 4 - Kowa Spherical image (@mariocontini) 5 - GL Leica-R Set 6 - Leica-R image (@miss_ashcon) 7 - Leica-R 15mm T2.8 Image 8 - P+S Technik Hasselblad Set 9 - Hasselblad image (@marianneleawilliams) 10 - TLS Zeiss Super Speed B-Speed Set 11 - Super Speed image (@traviswaddell) 12 - GL Minolta Rokkor Prime Set (@ancientoptics) 13 - GL Konica Hexanon Set (@ancientoptics) 14 - TLS Canon FD Set 15 - TLS Cooke Speed Panchro Set 16 - Cooke Panchro image (@Eli.goldstein.dp) 17 - GL Canon Rangefinder Set Not pictured: Zero Optik Olympus OM Primes TLS Petzval 58mm and 85mm Primes Century Kinoptik 9.8mm T2.3 Century 300mm Canon FD Richard Gale Optics Clavius Primes
