What are the best lens adapters for putting vintage glass on L-mount cameras, specifically M42 and Leica M mount?
I just picked up a Lumix S5II for a documentary project next month and want to use some old Takumars I inherited. I saw people recommending Urth because they are cheap, but then others online say Novoflex is the only way to go if you want actual precision and no light leaks. The Novoflex ones are like 200 bucks though which feels crazy for a dumb metal tube when my budget is kinda tight after buying the camera. Are the cheap ones actually gonna mess up my infinity focus or is there a good middle ground?

Ive tried a bunch of these and unfortunately had issues with the cheap ones.
- Urth M42 to L-Mount Lens Adapter: Cheap but not as good as expected, had slight play on my S5 and missed infinity.
- K&F Concept M42 to L-Mount Adapter: Better middle ground. Tight fit, no leaks, and way cheaper than Novoflex. Let me know if you want recommendations for the M-mount ones too!

Just catching up on this thread and I gotta share my experience! I spent years shooting docs with old Takumars on my Panasonic gear and went through a ton of adapters. Building on the earlier suggestion, you definitely dont need to drop $200 on Novoflex to get perfect infinity focus. Here is what worked for me:
- For your Takumars: The Fotodiox Pro Lens Mount Adapter M42 to L-Mount is my absolute favorite! It is brass, super solid, and only costs about $35.
- For M-mount: The 7artisans Leica M to L-Mount Adapter is fantastic and costs around $40. I shot a whole indie doc last year with this exact setup on my S5II and had zero issues with infinity focus or light leaks. You are gonna love the look of those old Takumars on that sensor!

- My first cheap adapter was off by 0.12mm, destroying infinity focus.
- Internal reflections on the matte paint ruined my contrast.
- The one I got later finally kept the correct flange distance.

Building on the earlier suggestion, I'm actually facing this exact same dilemma with my S5II. I've been hunting for weeks because I'm genuinely terrified of ruining my camera mount with a cheap, poorly machined ring, but paying $200 for a simple metal tube feels like a robbery. It is incredibly frustrating that we can't find a reliable, safe middle ground.
