Hello, the adapter should be used with manual lenses from the analog era, logically. On an Olympus E-PL7, I was curious about the usability and above all the achievable image quality. Since of course there is no electronic data exchange between the camera, lens and lens adapter, the camera or the image stabilizer should/can be set first to prevent camera shake Reduce. To do this, press the OK button, bring the image stabilizer to the desired setting. Then simply press the Info button and set the originally used focal length at the bottom right and you're done. The lenses came, to name just two, the Olympus G-Zuiko 1:3.5/28mm and the telephoto lens Olympus E-Zuiko 1: 4.0/200 mm. Of course, these are also used analogously on an Olympus OM-4 Ti. The adapter is well made and makes a solid impression. However, he has a slight lateral play on the bayonet. I guess less than a millimeter. But this doesn't affect the focusing at all, at least not with my lenses. I've experienced other things, and even without an adapter solution. So nothing earth-shattering, especially not at this low price. Of course it will then the camera, with the adapter and, for example, a G-Zuiko 3.5 28mm no case more suitable for jackets, and at almost 630 grams also heavier than, for example, with the Lumix 1:1.7 25mm at almost 490 grams. I like this Lumix, no question about it, but compared to the G-Zuiko 3.5 28mm, it seems to be attached to the camera, I would say "less high quality". If you have problems with manual focusing on an E-PL7, for example, I can recommend the Olympus VF-4 attachable viewfinder. The thing is great, so it can be adjusted well without a sectional image and/or microprism ring, as is the case in many analog cameras. Of course, focus peaking can also be used, but this function must then be assigned a button in the menu, e.g. the Fn button for quick access. The test JPEG photos I uploaded are all unprocessed and show quite good sharpness, colors and contrasts. My conclusion: Recommended and inexpensive adapter solution, but also with a slight tolerance on the bayonet.

I have 7 K&F adapters...all great, all fit, no problems...I use them on 2 MFT cameras - Olympus and Panasonic...great to put on

ordered this adapter to use my old, manual Pentax lenses (e.g. SMC M 40 1.7) on my new Olympus OM-D E-M10 II. The lenses work perfectly with this adapter on my camera. The adapter fits tightly and without play in the camera mount on the Olympus and snaps in securely. No crunching or scratching when screwing in. The PK lenses can also be screwed in without any problems, but have a little rotational play. There is no light anywhere and there is no rattling or wobbling. Therefore, a perfect function is guaranteed. Unfortunately, the red dot for attaching the adapter to the camera is offset by about 2mm and is therefore only a rough guide. You get used to this very quickly. The workmanship is neat and the adapter is made entirely of aluminum - makes a solid impression! Overall I would give 4 stars. Because of the top price I give it an extra star. I can give a clear buy recommendation for the price of only €17!

use this adapter on my Olympus OM-D EM-10 to be able to use my Nikon G and Nikon D lenses with it. When I unpacked the adapter I was extremely surprised by the weight and the grip. I didn't expect this cheap adapter to be so well made. Then I immediately screwed my heavy Nikkor lenses on it and was just happy, no wobbling, no play - absolutely nothing! I don't know yet what the long-term test will show, but I think it will continue to be positive. :)

In order to be able to use my Nikon lenses with my Olympus OM-D E-M10, I bought this adapter and was absolutely surprised: the back flange dimensions fit perfectly, both the adapter and the lenses snap in nicely. But the big hammer is the aperture ring on the adapter. It runs buttery smooth and has six soft detents. From the open aperture you can stop down by approx. 1 f-stop, so that the range is open up to approx. one-thirtieth f-stop (always calculated from the maximum focal length of the lens)

I like the adapter very much. It fits perfectly on my Olympus MFT camera and is solidly made. Now I can at least use the "ancient" lenses including filters and other lenses manually again.

still had 3 older lenses from Minolta, which I couldn't part with, but I couldn't use them on my Olympus either. After a long search I found this adapter. Ordered, tried and everything was fine. Nothing wobbles and everything fits perfectly. And I can use my lenses again. Good price and recommended.

The adapter fits very well on both sides. I use it on an Olympus OM-D. For the other side I use my "old" Minolta lenses. So far I'm very satisfied.
