K&F Concept M20101 Leica M Lenses to Sony E Lens Mount Adapter

Instructions for use

Attention:
• Manual adapter without autofocus or aperture ring.
• Skillful installation, needn't too much force.

'No Lens Attached' - Warning Message Appears:

• If your camera indicates "lens is not properly installed", please modify the camera settings: 'Menu' -> 'Setup' -> 'Release w/o Lens' -> 'Enable' (Exact naming and location may change depending on camera model). If your lens does not have a manual aperture control ring, it will stop down to its smallest f/stop by default.
• Set camera "release shutter without lens" to enable when using the adapter for the first time, or the camera will fail to recognize the lens and the shutter may not be released.

Features:

• Lens: LM Mount Lens
• Camera: NEX mount Cameras
• Compact and high quality with metal material
• Precise production to ensure the perfect fit
• Diaphragm control of the lens is set manually
• Allows focus infinity
• Elegant clear appearance

Infinity focus position:

• The position of the infinity mark [∞] of the telephoto lens is shifted slightly to the positive side to enable focus adjustment even when focus shift is caused due to temperature changes. The shift range is denoted by an L-shaped line, Be sure to check the focus through the viewfinder even when you shoot at infinity.

Note:

• L mount cameras are full-frame mirrorless cameras.
• Adapting APS-frame lens to full-frame camera may generate vignetting, which is not the problem of the adapter. Some cameras could correct it by adjusting to APSC.

90% perfection

Really well made and so very fine as a design item. Works really well. Fits really well. The only weakness is the glossy internal black finish that reflects some light sometimes and creates glare in some images. Paint your barrel internal shaft matt black K&F! C'mon! I spray painted the internals after taking it apart. It only takes 30 minutes. Taking into account a top quality adapter tears your money for over £100 this is a very good adapter if you are able to paint the insides. And it is incredibly heavy, but it feels superb.

My favourite adapters for vintage lenses!

Firstly, I have over 100 vintage lenses, so I've tried so many different adapters and this was the first K&F adapter that I bought in 2015 (I'm going through my old purchases to leave long-term reviews). Since then I've bought quite a few more K&F adapters for my other mount lenses, so at this point, you might be able to guess that I like these adapters a lot!

So why do I like them so much? They are not the cheapest adapters out there, but for the price, they are the best adapters I've tried so far. They fit onto the camera quite snuggly which is obviously a good thing and the same can be said for the lens side on the adapter. Overall build quality is very good, even better than I would expect at this price point, so I highly recommend these to anyone using vitnage lenses on modern cameras!

Insane value for money! A must-have!

Having just swapped over to Sony from Canon, after many years of being loyal to Canon and having many of their lenses, I ended up with a few of their cheaper lenses that simply weren't really worth selling as the shipping and hassle would've been more than what the lenses are worth.

So I decided to put the lenses to good use with my new A7 III, but I first needed an adapter. Enter this adapter. It's incredible!

Sure, it only allows for manual focus, even though my Canon lenses are AF, but who cares? This adapter has allowed me to get back to basics with my camera and enjoy photography, almost at grassroots level. It's so refreshing, especially with photography being my main business.

The adapter is built like a tank, and together with its box, it fits comfortably into my camera bag. I don't go anywhere without it.

good adapter for camera lenses

I used this to adapt an older Nikon lens to my Sony A7iii cameraFit and finish of the unit is good and it does all that it was expected to do - there is no connection between the lens and the camera as it is full manual focus and f stop adjustmentif you accept this, then this adapter works just fineI can now use my larger old telephoto lens manually on my Sony camera

Cheap and effective solution

I knew this didn't autofocus - although it does meter correctly - when I bought it so that's not an issue. It's turned out to be an extremely cheap and cheerful way to try out my Nikon lens collection on an e-mount camera. Works a treat!

They give new life to your old glass

As with all K&F Concept Lens Mount Adaptors they are well made, provide a good fit and work as described. I have nearly a full set of the various mounts they produce and I have never had any issues with them at all. They have given new life to my vintage lenses, which in turn has given new life to my photography.
