Please post images taken with your manual focus 7Artisans/TTArtisan/DJ Optical lens or lenses. What qualifies as DJ Optical isn't clean cut. @SonnarGauss pointed out here:
Artizlab/Funleader, Mandler (rebranded Polar), and Peace use the DJ Optical factory. A reddit post with a Leica Discord screenshot claims the same (feel free to ignore if you're not a fan):
When there's money involved, every company in the world uses their strategic advantage(s) for profit, so please refrain from "knock-off" or "that should be illegal" discussion and focus on posting images.
Obviously these lenses are **NOT** for everyone, but as a hobbyist with emphasis on hobby, I appreciate the price/performance. And as someone with more than a fair share of character flaws, I often gravitate towards flawed lenses. ¯_(ツ_/¯
