Nikon G/F/AI/AIS/D Lenses to M43 MFT Lens Mount Adapter K&F Concept M18121 Lens Adapter

Foreword: I've been a Nikon disciple for years and accordingly already have some nice lenses for Nikon DSLR cameras. A few months ago my work bought a Panasonic GH5 for filming projects and now I wanted to be able to adapt my existing lenses to the new camera. Since I have already had good experiences with K&F Concept, the decision on an adapter was easy. Review: The adapter arrived well and safely packed in a small plastic box, which is also great for further transport and storage. First of all, it must be said that the adapter itself is unfortunately "stupid". It does not offer any electronics with which the camera can communicate. But this has one advantage: a very reasonable price. The camera also doesn't seem to have any problems with exposure metering. For the example photos (GH5 with Sigma 35mm 1.4 with an open aperture) I used the aperture priority. The aperture setting ring feels very valuable - as does the rest of the adapter. Nothing rattles, nothing looks fragile, the teeth snap into place cleanly. Personally, I would have wished for a slightly larger setting range for the aperture, but after a short period of getting used to it, you get along well with it. Overall, I can recommend the adapter without reservation. If you have any questions, please ask, I'll try to answer them as soon as possible :-)

bought the adapter to use my old analogue treasures from my Minolta Dynax 7000i on my new Panasonic Luminx DMC-G6. However, since I have already bought several lenses for the G6 and do not use the old ones that often, I decided on an inexpensive adapter, but also tested the expensive ones. In terms of quality, this is unbeatable in terms of value for money. The lens is really tight, without wobbling on the adapter and the adapter is also firmly in the camera bayonets. With the lenses that cannot set the aperture directly on the lens, I use the "Release without lens" mode on the camera and set the camera so that it finds the exposure time and the ISO value itself, this also creates " satisfactory photos" with an open aperture. The difference to the more expensive adapters is really very small in terms of quality and whoever buys a VW Golf does not expect a BMW 7 Series. So if you are looking for a suitable solution for little money to reuse your old lenses, you have come to the right place. I can only recommend the adapter to everyone, I would buy it again in a heartbeat. I wish everyone who decides to buy a lot of fun with it, the KF products are of significantly higher quality than the price suggests. The shipping from China was also quick and easy, my questions were answered quickly by the service. I am very satisfied and will probably buy more camera accessories from the seller in the future.

Fits well and worth getting a few lenses back into play

I already own one or the other adapter to adapt different lenses to MFT or Nikon, but PK to MFT is the first. The workmanship is good for the price, but the aperture driver on the lens grinded. This was very ugly and prevented the lens from snapping into its final position. Maybe it was the lens, it's a very old but fast port with an aperture of 1.2 - yes 1:1.2! After carefully bending the aperture driver outwards a little - bending is an exaggeration, it was less than 1mm - the lens then connected without any problems. I deduct 1 star because it could have been the lens and I don't have a 2nd to verify it. In any case, it took me some time to figure out what it was. There is also a trigger because the driver scratched the bayonet from the lens.

The adapter is used on a Lumix GF6. It is made entirely of metal, is very valuable and fits 100% exactly on the mft connection. Glides smoothly into the snap-in point on the camera body with a soft click. Nothing wobbles and everything is tight without any play. It's the same on the lens side. With a soft click, the lens snaps into place without binding. It can be released just as easily by gently pressing the release button. I've been using this adapter for about 3 weeks now and have taken about 500 photos with it. The resulting images are great. I can't report any flat images, lack of contrast due to any areas where light could enter the adapter. On the contrary, depending on the camera setting, the images are crisp and sharp, with a nice bokeh, or, or, or. I mainly use a Minolta MC Rokkor PG. 1:1.4 - f: 50mm. You can even activate the magnifying glass function with a tap on the touch display, so that the subject can be sharply enlarged without any problems. It may be that the more expensive adapters, which are around €100, are of even better quality - but I can't imagine whether I could tell the difference in a blind test. I have absolutely nothing to complain about on this part and am very pleased to be able to use all of these old analogue lenses for a small fee. Among other things, I also have a Vivitar with f:100-300mm that weighs 904 grams, hanging on the adapter, and I then took pictures from the tripod. This almost kilogram of glass didn't impress the adapter in any way, the telephoto hung on the camera just as tightly and without play as the much smaller lenses and takes first-class pictures. Based on this experience, I can recommend the adapter without reservation.

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.

Summary: My experience is consistent with the positive experience of other reviewers. Purpose of purchase: The K&F Concept Adapter was purchased to use my Nikon & Tamron full-frame lenses (primarily the Nikon 50s and the Tamron 90s macro) on my Olympus OM-D E-M5 (MK 1). Result of the first short test (approx. 20 minutes): The adapter fits 100% precisely and has no play, the aperture grid runs very smoothly (6 audible grids) and covers all aperture values of the lenses I tested, which means the adapter is in the Ability to fully open and fully close the aperture (tested with Nikon G 50/1.4 and Tamron 90 SP VC Macro (F2.8 to F32)). The surface finish is also of high quality (much higher than the price suggests) - one possibility for optimization would be the continuous matting of the inside of the adapter to prevent light reflections. But that's whining at an absolutely high level and not feasible at the price. Such an optimization can also be done later - just search for "dead matt black optical color" there are tips from telescope construction (at your own risk!!). The test was carried out at close range (apartment), ie the infinity setting has not yet been tested - but based on the reports of other reviewers, this should not be a problem. A positive surprise for the "hammer price" (the 2nd this year for a Chinese product) - there are still quite high-quality and inexpensive products on the photo market. I'm curious how the adapter performs in the long-term test - the critical point here would only be a defect in the lens lock, since the adapted lens could then no longer be removed from the adapter.... I certainly wouldn't have afforded the alternative Novoflex adapter because of the use of the "heavy" full-frame lenses on the M5 only makes limited sense due to the weight distribution (the 90s Tamron on the M5 became quite unwieldy without a handle because it was top-heavy) and the M5 due to the lack of focus peaking (I know the "helpful solution") for the use of manual lenses is also only suboptimally equipped. This is not intended to be a criticism of the Novoflex adapter, which is probably even better processed and offers further advantages (e.g. the use of an additional adapter (approx. 100 EUR) to relieve the camera bayonet) but costs 10 times the price and that's it for me then not worth it in my usage scenario. A big thank you also to the other reviewers as very helpful for the product selection. ...and no, I'm not a "bought" reviewer and I'm also pretty "old school" - ie quite demanding and critical when it comes to the general quality of photo accessories.

bought the adapter because I also want to use my existing Nikon lenses on the new BMPCC4K. Since the vast majority of lenses have an aperture lever, they can also be used although they do not have a separate aperture ring (lenses without an E-mark!). The adapter makes a very valuable impression. It is made of metal and feels good in the hand. It easily connects to the camera and lens. I haven't found any game so far. If this occurs during use and possibly leads to scattered light, I will provide an update. The adapter is delivered in a small plastic box. This makes it easy to store or transport when not in use. The silver ring is used to set the aperture. However, there are no numbers, only a symbol for an open and one for a closed aperture. But you can see directly on the display how turning the ring affects the brightness. So I don't miss numbers. In addition, I have read on other adapters with numbers on the ring that these values are not as finely graded as the numbers make it seem. I am very happy with this adapter. Of course, you lose light intensity because every assembly between the lens and the sensor "swallows" light. But this adapter only costs a fraction of what a Speed Booster costs. Also, you can't get a speed booster with contacts for Nikon lenses. No information is passed on to the camera, so you have to set everything manually even when using a speed booster. I can highly recommend this adapter to anyone who can get along with a somewhat lower light intensity.

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

The adapter may look a bit old-fashioned, but it fits perfectly with my 70-210/4.0. It is well made, the mechanism for releasing the lens looks a bit flimsy. But it works perfectly. Now have a 140 to 420mm lens on Micro Four Thirds, and anyone who knows the 'Beercan' knows the quality. The lens does not record, has hardly any CA's and is crisp at aperture 8. Thanks to this adapter I can use it again and I'm super happy, because I think a corresponding autofocus lens costs at least a thousand.
