Follow focus gears for Zeiss-Yashica Contax R (Y/C lenses)

cults3d

A precision-crafted 360-degree follow focus gear set for Contax lenses, featuring a two-part assembly that makes mounting, removing, and adjusting a breeze. Either 10mm or 12mm wide options are available. The clever design of the gear ring ensures easy handling, with an outside diameter that remains consistent across all lenses. A split-ring of variable thickness sits beneath the gear, securely holding it in place via compression fit. The rubber lens grip provides a solid foundation, while FDM print layer-lines add to the rigidity of the assembly. Several sizes of split rings are included to accommodate different lens requirements, with the thickness chosen specifically for FDM 3D prints. Most lenses work seamlessly with the gear v3 + 5.4mm ring, including popular options like the 80/2.8, 50/1.4, and 35/2.8. Yashica's 21/f3.5 and ML Macro 55/2.8 lenses use the 6.65mm ring, while Zeiss Sonnar's 100/f3.5 lens requires the 6.15mm ring. The inside diameter of the gear rings is 75mm, allowing for easy calculation of compatible lens diameters. A generous leeway of around 1mm or more is usually available, even accounting for print variations. The latest version, v4, includes a short pan arm for precise movements, taking your focus to new heights. Six split rings are included: 1.75, 2.7, 3.1, 5.4, 6.15, and 6.65mm. These precision-crafted follow focus gear sets were designed in response to the frustration of using inferior products with screws, clamps, or rubber clips that often resulted in backlash, cumbersome fixings, or time-consuming adjustments. These gear sets are a game-changer, delivering unparalleled performance and reliability.
