K&F Concept M42 Lens to Micro 4/3 Lens Adapter,M42 Screw Mount to Micro Four Thirds M43 MFT Fits for Olympus PE, Panasonic Lumix

I have a handful of old Pentax lens and wanted to try some out on my Panasonic G7. Had no issues with mounting and everything works great. Tried photos and video and the quality was still there.

This is an excellent product, worth the slightly higher price compared to bargain adapters. It is solid and secure, rotating into place with a satisfying click. I can't comment on that auto focus aspect, because I use this adapter only with manual lenses. But in all respects that I'm familiar with, this adapter functions very well.

Excellent product! Shipping was a long wait, but it was worth it! Great craftsmanship, looks exactly as pictured in every detail, more than I can say about other adapters I ordered that only looked great on pictures. Pros: - Very good smooth paint finish - All metal construction - Durable (been using it over a year now) - The lens screwed in the correct way (not upside down) - Snug fit to my Lumix GH2, no jiggle. I cannot find any Cons...this is just a beautifully made M42 to micro four 3rd lens adapter. Even the product packaging looks good. Highly recommended for those looking for M42 Screw Mount Lens to Micro 4/3 adapter. Now I can finally use my Yashica Yashinon-DS 50mm f/1.9 on my GH2. (I'll add photos when I can) -Update: Over a year later & the adapter is still in very good shape! (04.24.2016)

Got some funky lenses recently through various camera acquisitions and I thought it'd be fun to try them on my Olympus EM1 Mk2, particularly the 400mm that steps up to 80mm on MFT cameras. The adapter works flawlessly! It;'s solidly built and I've had no issues or wobbling. I would not hesitate if you need to adapt some old glass to mft cameras!

This is a solidly built piece of equipment and may deserve five stars not four because it works every bit as well as described. Here's why I gave it only four: I have a collection of old lenses gathered over years of my photography hobby and I was really interested and enthusiastic about expanding the capabilities of my micro four-thirds Panasonic GX7. In truth it works but defeats the object of a high-performing lightweight camera. I think, from careful viewing of the results that the crop factor magnifies the imperfections of legacy lenses so the get the hoped-for results you have to use the only the very best of them. Add to this the extra bulk and weight of the old lenses, and their inability to integrate with so many of the features of a modern digital camera which you've become used to using and you may wish to consider if it's practical. But hey it is fun, I grant.

Works exactly as intended. Great for any old M42 lenses as long as you plan on using them manually. I have had no problems with the image quality out of my camera using lenses with this adapter so it gets 5 stars.

The product itself is built well and high quality. Unfortunately, it did not work for my lens. I was trying to adapt my vintage meteor 17-69 lens from my Krasnogorsk-3 to my bmpcc4k. The ring on the inside of the adapter made it so the lens didn't fit into the adapter. Just a heads up if anyone is buying for this lens.

Works perfect for my camera. Let’s me use all my vintage lenses on my newer digital camera.
