K&F Concept M42 Lens to Micro 4/3 Lens Adapter,M42 Screw Mount to Micro Four Thirds M43 MFT Fits for Olympus PE, Panasonic Lumix

Tried to use this on my Lumix G85 and it does not maially focus AT ALL do it basically useless. Also when I use it, it grey's out my aperture so I can no longer change it. POS

I bought the Nikon G one. I can place my G and AI-S lenses on the Lumix G camera. As expected no autofocus. Also, aperture adjustment needs to be manual. it's great to be able to take pictures with high value lenses on a modern small camera body.The whole mount is made from metal. It feels of good value. I'd highly recommend it for people looking for the same.

I bought this to use some of my Canon and 3rd party EF lenses on an Olympus E-M1 Mark II camera. As I have most general lenses for the E-M1 I really only needed it for 2 of the EF lenses, one a Tamron 150-600 and the other a Canon 100mm Macro. Both worked properly with this adapter and I was able to get good sharp and very usable photos with it. However there are some restrictions with this adapter that should be mentioned.One, this is a "dumb" adapter in that it has no electronic components and thus there is no communications between the lens and the camera. That means that auto-focus, aperture adjustment and lens stabilization will NOT work. If you need those you need to look for some of the more expensive converters that contain electrical connections.Two, your camera will not know a lens is attached so you need to make sure you can shoot "without a lens".Third, since your lens becomes a strictly manual lens you can not adjust the aperture from the camera and you will either end up shooting wide open or you will have to set the aperture of your lens with the native camera for the lens and then find a way to dismount the lens without resetting the aperture. I do this with the DOF button on my Canon.Lastly, you have to be prepared to focus manually. If your camera provides "focus peaking" you might want to use that to get your shots in proper focus.If you are prepared to use your camera with the above restrictions this is a great little adapter and I have been able to use my EF lenses to good advantage and been very please with the results. The adapter seems solid and well made, but comes without any case or end caps to keep it clean and undamaged. Mine came in a plastic bag and I now store it, in my camera bag, in that plastic bag or leave it attached to one of my EF lenses in the lens case. Since this adapter fits an EF lens on one side and a M4/3 camera on the other you probably can also buy an Olympus lens end cap and the Canon camera body cap. That is what I plan to do to keep this clean.

Family had a bunch of Canon lenses for the photo camera we've had for years (even a cool fish-eye lens) and I just purchased a Panasonic Lumix G85 as a graduation gift. Wanted to find an affordable adapter so I could use the 7 different lenses and this works perfectly! I tested all of them and was so happy to have all these options instead of having to save up and purchase a bunch more lenses down the road. The AF is something I haven't figured out yet, the Panasonic AF is also a tough subject for me since I practically just got this camera. Maybe someone out there has advice, but for what I wanted, I definitely got it!

Finally an adapter that has a aperture control and has NO problem with infinite focus, using Nikon lenses and E-M10 Mark IV camera.I tried three different brands and designs before finding this one.One feature that will make this the perfect adapter is a mount to a tripod to hold heavy lenses instead of leaning all the weight on the camera.

Attaching the adapter was variable. Easier on my old zoom lens (a nice satisfying click) and difficult on the 50 mm (just have to tighten down). Setting up the accepting camera (Olympus E-PL5) is a nightmare.The 50mm is ok, but probably not as good as the native Olympus lens. The 70-210 zoom lens pictures are ok in brighter light. In any less, focus is pretty bad. Admittedly, the Olympus is it's own ongoing nightmare with hideous menu UI, but that's a different issue. Maybe fiddling with that more will help.I was hoping I could repurpose those two of my old lenses, especially the old Canon FD zoom-macro. Maybe if I dig into the nightmare Olympus menu options more I will change my opinion. But so far, it's less than a stellar experience and feels very restrictive.On the other hand, it's not an expensive piece and it does allow the nostalgia of using those old lenses once in a while just for fun. Man, they are heavy though!

The K & R Concept Lens Mount Adapter for Nikon F mount lenses to Micro Thirds camera bodies does exactly what it was designed to do. I have tested it with a Blackmagic Pocket Cinema Camera using Nikon glass, both an AFS DX 55-200mm f4-5.6G and a 50mm f1.8D. Both worked.Since the 50mm f1.8D has an aperture ring, you can use the adapter or the aperture ring on the lens to control the iris function. With a Nikon "G" lens, you must use the adapter to control the iris. If there is a downside to the adapter, it is that there are only six clicks between wide open and stopped down and there are no markings to indicate the correlation between the adapter's clicks and the lens's F stop. Having read a previous reviewer's comments, I was aware of this, however, so it was no surprise. The BMPCC has a histogram, so that can be used for exposure metering. Previously, I have used a Nikon 50mm f1.4 non-AIS on a D5100 body. With that set up, there is no exposure metering either. You can check exposure by eye through live view or use a light meter.So, if you absolutely need to know the F stop value you're shooting in, then this adapter is not the one. Certainly a Metabones Speedbooster is a better option as it is calibrated and clearly marked - the caveat being that it is also significantly more expensive. If you're comfortable using additional tools to check exposure or don't mind eyeballing it, then this is a great value for $16.99.

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.

Works fine now but originally my Helios 44-2 was mounted upside down. At front of the adapter three screws needed to be loosened to rotate the mount 180 degrees. I did that but had to find out what sort of screws they were. Not immediately apparent. Discovered it needed a T5 star pointed bit to do the job. Hope this helps any future buyers.

A friend gave me an old M42 200 mm lens since hewas unable to make use of it. I bpoght this adapter to see if the lens was still viable. The adapter connects to both the lens and the camera very positively and cleanly. A good sign is that the red focussing mark and the aperture equivalent are top dead centre.The lens is of the early aperture preset type where you set the desired aperture, but the lens remains fully open until you spin the ring adjacent to the aperture ring to close down prior to exposure.Clearly one can either use a meter and set the shutter speed manually or leave the camera meter to set it at the time of exposure. Clearly the exposure time displayed will only be accurate with the lens stopped down. Focus will obviously be manual, but with Olympus bodies you will get image stabilisation if you manually set the focal length.An interesting experience using a lens designed for cameras several generations of development back, pretty well using the same techniques we were using 60 years ago.This adapter feels so well made that it was a pleasure to use it.

Got this to enable connection of my Nikon lenses to a Lumix GX9. Not disappointed as I can now use my arsenal of Nikon lenses on a Panasonic camera for a cost of just £20! As expected all these lenses only operate in manual mode as there are no electrical contact between lens and camera. Fortunately, the Lumix got focus peaking which works well most of the time. Aperture settings are a hit and miss affair but results are good most of the time. Impressed with the results using my Nikon 35mm lens (my favourite) even in poor light - super sharp. Also got reasonable results with Nikon 10.5mm fisheye. I considered giving just 4 stars because aperture control becomes poor (this apply to other adapters too), but have to accept this limitation. Would recommend if you can accept the limitations.

I wanted to use my Canon 60mm Macro lens with my Micro Four Thirds system camera so I bought one of these. I knew that there were no electrical connections between the adapter and the camera so the would be no means of auto focus etc. but I'm old enough to have used camera long before auto focus came on the scene so it held no fears for me. The day after it arrived I mounted it on the canon and then onto the Olympus and after hearing the satisfying 'Click' as it locked on. I focused the lens and suddenly every thing was pin sharp. I had turned my 60mm macro into a 120mm Macro for a fraction of the cost of a new lens. really good value for money.
