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.

As many have said this adapter is beautifully engineered and has a solid no-nonsense feel and weight to it. It has its own plastic clip-lid box. This (together with a Nikon G adapter from the same company) was the second I ordered in two days as I found a M42 lens just after I had ordered the Nikon adapter. They are both superb and literally - if you look at the illustration on the box lid - do what the box says they do. In the case of the older screw in lens attachment takes seconds and the installation is firm and solid. A few words of caution however. Your camera and the lens it has available for it have been designed as a system. Everything is balanced in terms of size and weight - things you considered and appealed to you when you bought it. Adding a lens not designed for your camera will throw all out of balance - literally. In addition lens designed and made decades ago were the best they could be for the price at the time. Their performance was often stellar, sometimes rubbish and usually OK. In some ways these lens can be seen as motor cars from the 1960s. You may admire a classic sports car like an E-type Jaguar or similar. You may have had one at the time and remember how it performed or you may simply want to drive one. But the experience may not be as you remember or imagine. Your beautiful head turning sleek car is probably very uncomfortable by today’s standards. You may not be able to find some where to drive it to the maximum. It may become a ‘Sunny Sunday’ car, only coming out when the weather is perfect and sitting in the garage most of the time. Your old lens may be like that sports car. ‘Good glass’ optimised for film cameras from years ago may be unforgiving on a digital sensor. Modern focusing aids like peak focusing may not always work. Your idea of getting a cool looking cheap super telephoto lens by using an adapter on a 2x crop sensor in practice may result in a ‘monster’ you can use only in certain specific, limited circumstances. And as stated at the top of this review your camera may feel heavy and unbalanced - something to consider, especially if you have small hands or arthritis. But if you have read this far and are prepared to accept that you may not get an award winning photo first time - or indeed ever - simply want to experiment and at the same time improve or recapture your photographic skills and not rely on your modern digital camera doing all the thinking, then your camera, this adapter and that lens in the garage or cupboard or drawer will get along fine. And best of all you will have fun and may even surprise yourself.

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

Got this adapter for my GH5 to fit some vintage Fujca lens's inherited from my late uncles camera. Build quality is good and the lens is sturdy when mounted. For the cost its a no brainer, id recommend to anyone wanting to use vintage lenses. The only issue I had was on a longer zoom lens ( 130mm ) did not have very good focus range, the focus range was very narrow and could not reach infinity. The 55mm I have also however works great.

This adaptor is a great fit on my GH5 for my Helios 44-M. No light leaks, easy to fit, doesn’t come loose when changing the lens. You do have to adjust the ibis (double the focal length, I use 116, so it’s a definite portrait lens) but it gives a new lease of life to a lovely lens. Everything works fine. Well worth it and gives you a great vintage lens in your kit.

Adattatore molto solido e senza nessun lasco. Consigliato!
