CLAed! Schneider-Kreuznach Radionar 7.5 cm 7,5cm f/2.9 Lens for Reflex Korelle

Description: Up for sale is an uncommon German-made lens for Reflex-Korelle 6x6 Medium Format SLR cameras, the Schneider Kreuznach Radionar 7.5cm f/2.9. This Cooke-Triplet formula lens produces astounding, swirly bokeh with lovely colors and rendition, with a relatively fast aperture for its design. It can be used natively on 40.5mm screw mount Reflex Korelles or adapted to a number of shorter flange-focal-distance formats. Nice vintage condition with light handling wear, minor ding in aperture ring (doesn't affect function). Faint cleaning marks front element coating. Otherwise scratch/haze/fungus-free. Lens has been disassembled and CLAed with complete helical relube for ultra-smooth performance. CLA FAQs This lens has been completely disassembled and CLAed (Cleaned/Lubed/Adjusted), with cleaning of individual components aperture cleaning and total helical cleaning/relube for like-new performance! Q: Why buy a CLAed lens? Put quite simply, lenses get dirty over time. Many used vintage sold lenses here on eBay are described as “mint condition,” typically meaning they are free of obvious optical flaws like haze or fungus and have a clean-appearing exterior. However, opening them up tells a quite different story. While these lenses may appear tightly built, they nearly all use open designs, which allows substantial amounts of dust, dirt, and grit to enter the lens, where it settles into delicate precision components, adversely affecting the mechanical properties of the lens and leading to increased wear. Furthermore, even in unused samples, lubricants tend to degrade over time, leading to degraded focus action as grease dries out, or slow blades and soiled optics as oil migrates within the lens. Q: What services do you perform on the lens before sale? With the lens disassembled, I perform a full CLA (Clean Lube Adjust). This entails cleaning out any internal and external soiling, cleaning aperture blades of grease that can slowing, re-lubing the focus helical, and adjusting all components for tightness and accuracy. Where there is extensive dust or internal lens soiling, I will disassemble lens cells and clean off surfaces; however, it is my general philosophy to keep lens elements in their factory positions in assembled cells when at all possible to ensure optimum performance. Q: DUST? What do you mean DUST? A: All vintage lenses have dust in them. In fact, they had dust in them when they were brand new from the factory! This is because prior to the advent of very modern sealed designs, lenses were not put together in a clean room environment, and the natural static charge of the glass tends to attract dust particles. Coupled with the open designs used in these lenses, it is virtually impossible to find any vintage lens without some degree of dust particles visible when you look closely through the lens. All of my CLA lenses have at minimum the exterior and internal cell surfaces wiped with a dust-free, lab-grade optical tissue and then blown off with an air bulb prior to reassembly and thus have a significantly below average amount of dust for a vintage lens. m069
