Adjustment ring corresponds to the good quality of realization.

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'm really very happy with the purchase, this adapter is amazing, the membrane ring is very fluid. The good thing is that the system for opening the aperture works perfectly with Nikkor lenses, Nikon G, Tamron (Nikon mount), Sigma (Nikon mount), something I didn't find in my old adapters (they only worked with Nikon brand lenses). Besides the excellent functionality, it is also easy on the eye. It's not very heavy, but not too light either, suggesting the use of "full" materials.

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.

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.

Perfect service

Since I recently inherited a Nikon FG-20 as well as a Nikon Micro-Nikkor 55mm f/2.8 and a Nikon Series E manual focus zoom 70-210mmf/4.0s, I naturally wanted to use the old lenses on my Canon EOS 600D or EOS 600D Review Canon EOS 760D. But: Nikon on Canon? It is well known that this is not possible without an adapter ring. Novoflex adapters were out of the question for me, because as a hobby photographer and occasional "analogue photographer", I didn't want to spend €100 on such a ring. Nevertheless, I wanted to break THE primal law of photography and combine Nikon and Canon. K&F Concept offered a cheap alternative for just under €20. The adapter ring is surprisingly high-quality and made of metal, and it can also be quickly mounted on the lens and DSLR. I was surprised by the results (see photos) and would not have thought that the two 30-year-olds "harmonize" so wonderfully with my EOS, to put it bluntly. It's a bit "hooky" to detach the adapter ring from the lens again using a tiny little "hook" (if you can call it that...), so the ring gets a star deduction, because it gave me a bit of a panic at first and I'm not sure how long this "hook" will go along with the whole procedure. ! A NOTICE ! You should really inform yourself in detail about the bayonet (connection of the lens) beforehand. Since the two Nikon lenses are both a bit older and were built in a time when people would have laughed about something like the internet in this country, it was a bit difficult to find out exactly (especially as a layman or newcomer to Nikon and analogue photography) whether they both have the same connection and whether I might even have to buy two different rings.

The lens is securely attached to the adapter ring and this is precisely and stably inserted into the camera body. The Nikon Nikkor lens is on a Nikon Z camera. The adapter is well made and has an opaque interior to prevent reflections. I'm giving it 3 stars for value for money, not because it's obviously bad, but because it costs more than other mount/camera body combos. The whole thing deserves 5 stars because it works very well.
