thingiverse

"SLR magic 18mm F2.8 CINE" It is said that the lens has the following characteristics. (the description of the sales site - "B&H") "Whether shooting in cramped quarters, in front of vast landscapes, or any other situation where an ultra-wide field of view is required, the SLR Magic CINE 18mm f/2.8 Lens will have you covered. Its fully mechanical design is robust, lightweight, and reliable. Its light weight and naturally wide depth-of-field makes this lens a great choice for stabilizer or gimbal work. The 0.8 MOD gearing on both the focus and iris lenses ensures connectivity with follow focuses and lens motors. Further reducing the weight of your rig, 62mm front filter threads allow for mounting standard photographic filters rather than using a potentially heavy matte box." In my personal opinion, it is a compact wide-angle lens cine lens and is a manual-only lens, so it has a sturdy and robust operation for focusing or stepless aperture. However, despite being a small lens, it is quite heavy. And the small focus and aperture-controlled gearing were inconvenient to operate. So, to improve this, we challenged custom lens rehousing. Designed to secure the lens re-housing using grub screws (M4 and M5) and a 62-82mm step-up filter ring. Add focus handle (handle or tap) for handheld shooting, apply 0.8M standardized forcu and aperture gear ratio, focus gear outer diameter is 100mm (123T). (Designed with the same consistent specifications as the vintage lens re-housing) Parts - M4 x4mm (9ea) Grub screws - M4 x 18mm (1ea) screw _ 62-82mm Step-up ring (filter adapter)
