Disassembling, cleaning mir-1b 37mm f2.8 89045432

Hi, my name is Dwayne, and I'm all about vintage lenses – the kind that you sekali cuba, hari hari mahu. Which is exactly what happened to Mr. Andrew after he tried the Helios-44M. So, Mr. Andrew ordered a MIR-1B, this fantastic wide angle Soviet lens with that same mesmerizing swirly bokeh you get from the Helios 44 series. First, I carefully relubricated the focusing helicoid and aperture ring with Helimax XP NLGI #1 Lithium grease. Smooth as butter now. Then, I carefully cleaned those optics with IPA 99% to ensure there's not a smudge or mark left. Next, a little tweak for modern convenience. I modified the aperture ring to be a 'single action' champ, making it user-friendly for today's shooters. Swapping out those frail aluminum grub screws with gleaming stainless steel ones has transformed it into a lens as robust as a tank. I've reduced the minimum focusing distance from 0.7m to a convenient 0.5m. You'll be grateful for this in the future. Of course, I gave it a good test run. Focusing helicoid and aperture ring feel just right. There you have it. Mr. Andrew's MIR-1B is now a vintage lens wonder, ready to capture some cinematic magic. // Gears Used // Camera: ‪@ZCAMCC‬ E2C http://www.z-cam.com/e2c/ Focal Reducer: ‪@viltroxofficial‬ EF-M2 II https://shp.ee/nfs84tj Lens: MIR-1B 37mm f2.8 https://shope.ee/AK1FCRLFKb M42 to EF Adapter: https://shope.ee/3KwHv4QLL7 Filter Step Up Ring: https://shope.ee/5KhMImr7S7 SD Memory Card: ‪@SandiskCorp‬ Extreme Pro 64GB https://shp.ee/aznbidp Cage: ‪@SmallRigGlobal‬ Cage CVZ2372 https://shope.ee/q4TsUP4t7 Top Handle: ‪@SmallRigGlobal‬ 2165 https://shope.ee/1AhIic2z9E Edited in ‪@BlackmagicDesignOfficial‬ DaVinci Resolve Studio 18.5 Beta Film emulation with ‪@Dehancer‬ Pro 7 (Kodak Vision3 50D printed on Kodak 2383).
