K&F Concept Lens Mount Adapter Ring Compatible with Canon FD Lens to Micro Four Thirds M4/3 Olympus Pen and Panasonic Lumix Cameras

Don't be confused by what this adapter does and doesn't do. Many reviews and answered questions are misleading. Just to be absolutely clear, this adapter works with the Panasonic Lumix G7 body and Canon EF lenses, NOT Canon EF-s lenses. If your lenses have the RED dot, them this adapter will work for you. If they have the WHITE dot, then you will not be able to focus the lens when mounted and should not bother with it.K&F has a good product here. The ir build quality is very good and the adapter fits very snug on the camera and Canon lenses. K&F's description of the product is also accurate... it's for EF lenses. Just be advised that this is a mechanical adapter... it has NO electronics and your Lumix G7 will not be able to auto-focus an EF lens nor will it be able to adjust the aperture. Once an EF lens is mounted, you are on your own in the camera's manual mode only.Once you mount a lens on the G7, you will need to go into C mode (custom) on the settings dial and toggle down to turn ON the setting that allows the camera to operate without a lens. That will allow the shutter to operate. Unfortunately, the adapter does not come with instructions so this isn't obvious.Sadly, my EF-S lenses are the smaller ones that I wanted to use with the G7 and that is why I bought the adapter. Shame on me for not realizing that they are not what it was made for. Don't make the same mistake.

I have a Blackmagic Micro Cinema Camera that i almost bought a metabones adapter for when i stopped and thought....why would i purchase a metabones for it when i only use manual cinema lenses on it? Like Rokinon DS, Xeen, Zeiss, etc. So i went on Amazon and came across this. I was going to grab the Fotasy, but the way this one looked and the of it display just looked a bit cooler and for the price....why not just give it a try. So the first thing i noticed was the build quality....its amazing! Honestly it feels extremely solid and even stronger than my metabones, but its important to remember this is not a metabones, but if your using it for cinema work then its a great pick up. It fit very tight and clicked into my micro cinema. Like i said it is very tight and may feel like your going to damage something because you will feel a slight scraping, but not to worry because you really just need to break it in just like a metabones. Definitely a great buy and a must have. Will be purchasing a couple more.

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.

From all of the 3rd party adapters that I have tried, K&F have the best build. Its solid, the red alignment indication is clear and it doesn't feel like cheap plastic.Nevertheless, this time something was wrong and the adapter didn't fit as expected on my camera. So I reached out to the seller Hishop and to my full satisfaction, they handled my issue in the most professional manner. I would like to thank them for the professional customer service and hope to be there customer again.One last note: Amazon.com has a policy to blocks (removes) emails with certain attachments types - in my case it was an MP4 video clip.This is a bit annoying because I made a short video that demonstrate my issue, but couldn't send it as an email attachment.

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.

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.

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.

For the price this is a very well made bit of kit. I am giving it 5 stars because of the build quality and price. Nikon fit lenses do fit very well indeed but the M43 fit is very tight. But having said that, it means the lens is very secure with no play at all. If you use this on a lens with no f-stop ring then its all guess work - though you can still set the shutter speed and ISO. The ring on the adapter just lightens or darkens the EVF on an Olympus EM1 mark II. But it is a DUMB adapter, with no communication between the lens and camera, so it does exactly what I expected. I wanted to use my Nikon fit Sigma 180mm f2.8 OS macro lens on my EM1 mark II when looking to replace my Nikon system. It did work and I obtained good, detailed images of a bumble bee in flight. But, there are better macro options for my Olympus system and I wil not be using the adapter again. I did try it out on my Nikkor 200 - 500mm f5.6 on my EM1.2 but felt the images appeared somewhat soft.
