1st Generation

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.

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!

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)

Using this adapter for an old Helios 44-2 lens to GX1 and it works great. Construction feels solid, did not have any issues screwing in the lens. I've also tried another brand but they didn't attach very well to the lens. The only reason I didn't give it a full 5 stars is because as some others might have noticed, there's a very slight wiggle once everything is attached to the camera body for some reason. Otherwise this is a nice adapter without breaking your wallet, and a great way to revive older lenses. I'll probably buy a couple more different adapters from K&F.

Cheap and it does the job. Because this is for a crew mount lens, making sure that the holding screws are very tight is quite reevant, especially if your lens is a wide angle with a built in hood (like a Voigtlander 15mm). If not tight enough, the lens may rotate on the adaptor and give you unwanted, uneven vignettes. The manufacturers seem aware of this, as the adapter ships with a tiny Allen wrench tool to tighten the screws.

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.

As long as you remember this adapter is for lenses that will only allow you to focus manually, you will love this product. It is extremely well made and it will open of all sorts of great possibilities of new lenses to try out with your M43 mirrorless cameras. Excellent adapters like this one will really rekindle your love of photography, simply trying out some of that great vintage glass out there you can take with you on the road and bring back great pictures from completely new adventures. For the price, it's more than a bargain. I highly recommend the adapters from K&F.

I used this to convert a Takumar 135-200mm on to my G85. I picked up the lens cheap and figured why not? The adpter fit perfectly on both the lens and the camera, picture quality is outstanding and the build is excellent. Since ordering this I've have ordered 3 more of varying sizes and have been more than satisfied.

Exactly as described, works perfectly with my omd-em10 and takumar 55mm f1.8

I've used various convertors over the years to fit M42 lenses to digital cameras. This one is the best made I've ever had. It's a great snug fit to the camera and the lens. No play at all in the fitments. The lens works perfectly on my Panasonic G9 - better than on the Sony A99ii which preceded it. Spot on.

L'anello si adatta perfettamente al mio corpo macchina di una Lumix GH5 II e degli obiettivi vintage con attacco M42. La qualità è molto buona, non ci sono ovviamente pin per automatismi. Spedizione celere come sempre

Adattatore molto solido e senza nessun lasco. Consigliato!
