K&F Concept M18125 high-precision lens adapter ring, coated with matt paint, secondary oxidation orange, NIK(G)-M4/3
SKU: KF06.454
The price-performance ratio is right!
The goods arrived on time, as usual from K&F Concept. As far as I can tell as an ambitious hobby photographer, the product does what it promises. In any case, it meets my personal expectations. Its durability remains to be seen. However, based on my previous experience with other products from the company, I assume that this autofocus adapter will also serve for a long time. The feel and appearance are of high quality in my opinion.

This is a nice looking bit of kit, but its not the correct thickness. When measured flange to flange its 25.4mm but for old M42 full frame lenses to work on Micro Four Thirds it needs to be around 26.2. if you take the old full frame flange to sensor(film) distance of 45.46mm and subtract the MFT flange to sensor distance of 19.25mm you get the 26.2mm required. To get this adapter to work I had to unscrew the lens approximately 1.0mm to get infinity focus to the correct place which tally‘s with the maths.
This means when you set your manual lens to infinity focus you will get a blurry image. You will need to set your focus to 1.5 meters with a 35mm lens or 15 meters using a 135 mm lens to compensate or make some kind of packing washer to move the lens further away from your sensor.
Using the argument that it is designed to allow for lens tolerance is wrong, after all the old camera bodies worked fine. Plus camera bodies and lenses throughout the years were never manufactured to such sloppy tolerances. If this adapter was 26.1mm everything would be fine, the infinite focus would be so close to where it should be, as would all the other focus distances marked on the lens that there wouldn't be an issue.

Contrary to the experience of some others, I can find nothing but praise for this adapter.In use with an Olympus OMD E-M1 mark III and Canon FDn lenses, the adaptor has no play whatsoever on either camera body or lens, when mounted.
Before purchasing, I had watched several online videos explaining how to enable “off-camera” aperture adjustments on the FDn lenses, but have found that the easiest way to achieve this was to move the lens aperture control ring away from the green “A” setting and onto any actual f-stop setting, before taking the lens off the Canon camera body. (I am fortunate in still having a Canon A1 which enables me to do this).
Having done that, with the adapter then mounted onto the OMD body, and with its lock ring set to the “open” position, it is simply a matter of attaching the FDn lens to the adapter, and sliding the lock ring to the “lock” position.
That done, full manual aperture control of the lens becomes available by rotating the lens aperture ring to whichever aperture setting is required.
Note that although the E-M1 mark III body has inbuilt image stabilisation, in order to make the most of that facility, the camera needs to be “told” what focal length of Canon FDn lens is being used. (It is a simple matter to input that information via the OMD’s custom menu settings).
Enabling “focus-peaking” on the camera body makes fine control of manual focusing pretty much failsafe! (NB: I’m not sure if focus-peaking is available on all Olympus camera bodies).
Results thus far have been very good indeed, and have breathed a new and very useful life into my old FDn lenses. Exceptional results using my erstwhile “pride and joy” Canon FDn 85mm f1.2.
Well done to K&F Concept for making a good quality, easy to use adapter, at an affordable price!

I have used k&f before and the quality is good, but this k & f one with the Orange part is superior to whatever they build before. I woud buy this special adapter again and would recommend it.

I'm really happy with this adapter. I've used it on my Canon M50 with an old vintage Pentax mount lens and it works awesomely!

This is one of the best adapters for using old M42 mount lenses on a Micro Four Thirds camera. Given the quality of a decent vintage M42 lenses, putting them on a decent adapter is a must. These adapters are fantastic and rarely even need to be adjusted for infinity.
