Pentax K/M/A/FA/DA Lenses to M43 MFT Lens Mount Adapter K&F Concept M35121 Lens Adapter
SKU: KF06.312
The adapter fits well and does what it is supposed to do. You expand the type of pictures you take because new lenses or already existing other systems can be used so well. You just have to keep in mind that the electronics will not surpass and the autofocus. You would have to dig much deeper into your pocket for that. If that doesn't bother you, you can access it. I'm giving 4 stars so no one thinks this is a purchased review.

Bought the adapter specifically for filming with a Panasonic G6, it works as expected. The build quality is decent, especially considering the price of less than €20. Focusing to infinity is possible without any problems, so the adapter is not too long. Both sides lock neatly. The aperture setting via the ring on the adapter with Nikkor G lenses also works. There is a (small) negative point here: the path of the rotary ring on the adapter between opening and closing the aperture is quite short, so you don't have that many intermediate stages available. But I don't care, especially when filming, I use revelations 80% of the time anyway. Due to the nature of the principle, you cannot read the set f-number, but that is clear, that would only work with Nikkor D lenses (the old ones WITH an aperture ring). You can then adjust the aperture directly on the lens. All in all on par with relevant other China adapters, but at less than €20 it is significantly cheaper. Delivery by Amazon, so no long waiting time.

The adapter connects Nikon F lenses precisely to MFT Micro 4/3 cameras. The aperture ring can actually be used to adjust the aperture on the Nikon lens, but this is done too roughly. It is therefore advisable to set the aperture directly on the lens - if that is possible. However, the small switch for releasing the lens from the adapter ring is very stiff and you have to pull the switch out radially a little bit (a fraction of a millimeter) before you can even use the switch. Nevertheless, I give 4 stars because it works perfectly if you know this trick and you can get a large selection of lenses (e.g. the old Nikon lenses from the 80s/90s) inexpensively with this adapter and don't pay the super high MFT prices must.

use the Nikon / MFT adapter on a Panasonic G81. The adapter is very well made, the lenses fit tightly and without play (this is not the case with a cheaper Pentax / MFT). The integrated aperture ring operates the aperture in the lens, so that lenses without their own aperture rings can also be used. The picture quality is very good. A point deduction for the fact that the distance scale on the lens is no longer correct. The "infinity" range is now significantly earlier on the scale. If you set it to "infinity" without checking, the picture becomes blurred. But you quickly get used to it. All in all, a good way to continue using existing lenses for little money.

It's about the: K&F Concept Nikon AI(G)-M4/3 lens adapter with aperture ring. I would like to compare it with my Novoflex adapter for about 160 euros: The K&F has a much better fit on the Nikon lens side: it can be screwed in comfortably and easily. My Novoflex is so tight that I can only screw it in with force. The K&F has a much larger and more comfortable lever to unlock the Nikon lens again. With Novoflex, it is a very thin cylindrical lever that is often painful to operate because it presses into your fingers. The K&F has a much better grip ring for closing/opening the aperture. I don't know if the K&F is durable. My conclusion: the Novoflex was a bad buy. Too bad, because I like to support German products. The K&F is just fun and no problems. And should it break, I can buy 10 K&F for the price of the Novoflex.

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!

I bought this adapter to use Sony A-mount lenses from my Alpha 58 on the BlackMagic Cinema Micro. Am very happy with it. Nothing wobbles and there is no play. The wide-angle kit lens fits perfectly and the vignetting is not noticeable (logical! APS-C sensor of the Sony is larger than the 16 mm sensor of the BlackMagic). Lenses with a fixed focal length of 35 and 50 mm fit just as well. The only thing I haven't tried is the 50-200 zoom lens, but only because I don't plan on filming with it. Overall I am very satisfied and can recommend it. Of course, it has no electrical connection to the lens, so you can't use LANC to control the focus. But that should be obvious anyway given the low price. For such tasks you use active MFT lenses or a booster, but I haven't seen any speed boosters for A-mount yet.

For €16 I wasn't expecting much. I wanted to screw my buddy's Nikon lenses to my EM-10, so I ordered this adapter. The package arrived the next day and I was pleasantly surprised by the packaging and its contents. The adapter feels high quality (heavy) and stable and is easy to handle. The large silver aperture ring is easy to use. The adapter fits perfectly to my OMD and the Nikon lenses and can also be easily removed again. However, if you have an EM-10 with a small sensor, you should note that the focal lengths increase by a factor of 2 when using lenses that are actually intended for full format. In other words, you have a smaller picture section. But the adapter can't help it, because it does what it's supposed to and looks good at the same time and that's why I give it 5 stars!

Really not bad what you get here for the money. The adapter makes a solid impression, workmanship seems good. It is quite tight, has minimal play on the MFT connection but really to such a small extent that it does not affect the function at all. I stuck a small piece of tesa on the inside of the socket and now it is absolutely rock-solid, but it would have worked without the tesa. If there's one thing I would improve, it's the aperture ring: it could travel a little longer and snap a little harder. But that's really whining on a high level. Like I said, for the price I'm very happy. Compared to my Viltrox Speedbooster, it is definitely of a higher quality. You will see how durable it is, if necessary I will update the review.

In order to be able to use some of my Nikon lenses on my OM-D, I needed an adapter. This seemed worth trying because of the low price compared to the Novoflex, which costs 10x as much. My expectations in terms of material quality and workmanship were exceeded. Fits perfectly on the camera and lens. Only the aperture, which can no longer be set precisely, costs one star here. Nevertheless, I ordered a second adapter to be able to use the fisheye on the OM-D in addition to my telephoto without having to change the adapter. Attaching to the lens seems a bit fiddly to me. I award 10 out of 10 points in the price/performance category.
