As with all K&F Concept Lens Mount Adaptors they are well made, provide a good fit and work as described. I have nearly a full set of the various mounts they produce and I have never had any issues with them at all. They have given new life to my vintage lenses, which in turn has given new life to my photography.

Perfect for adapting my vintage manual focus lens to a digital camera. Great build quality!

No auto focus but wasn't in the specs and im more than happy with product as I don't often use auto focus

I was surprised with the build quality of this adapter, it being very good!However, I use a Fujinon 55mm f/1.8 manual lens with this on a Sony A6500, and I cannot focus to infinity.This is because the adapter needs to hold the lens ever-so-slightly closer to the sensor.I know it is not a problem with the lens as it focuses to infinity just fine on my actual M42 mount film camera.Any focus closer than infinity works just fine, it's just a little frustrating that I can't use this for landscape / long shots.

Amazing! It's my first adapter and it's so cool to see my 200mm lense get a second Life! The adapter quality is solid. I love the solid building quality and overall design of the adapter, as it matches the same aesthetic as the lense, mounting onto my Sony A7iii.I did however accidentally order the wrong mount at first, as it was a Bayonet Mount. Unaware of this, I had to return and purchase what's called the M42 mount (aka Screw Mount). Make sure you know what model you're looking for!

It does what it says it does. I just don't think its worth anything over $20 as you can buy the same product on ebay for far cheaper. But it adapts M42 lenses with no issue.
