Fits my pentax k lenses and my alpha 7 ii camera

have a Sony A7iii and I was looking for a good adapter for my 2 Canon lenses, 85mm f/1.2 and 11-24mm wide angle lens. This K&F Concept Adapter fits my Sony A7iii well and supports the lenses. I was skeptical about the sharpness of the photos. However, this adapter really nails the sharpness. It's better not to use the widest aperture, because lenses from other manufacturers work extremely poorly. Both sample photos were taken with this adapter. The shot in Florida was taken with the wide-angle lens. The mountains are recorded with 85mm. Autofocus is excellent on a 7iii body, so I didn't see any significant difference between using the adapter and the native lens. Eyefocus works very well even in low light conditions. The good thing is that I was expecting a lot of vignette, but I was surprised to find out that this lens doesn't produce a large amount of vignette. So the bottom line is that you should give this adapter a try. It fits well, not too tight like some cheap adapters. The build quality is really good. Happy clicking!

Hello everyone, since there are no reviews yet I thought I'd write one. The adapter arrived 4 days ago and was even faster than stated. So that's a plus point. Now to the adapter: It's just an adapter that allows you to attach the lenses to the Samsung (NX Mount). No electronic data is passed on to the camera or the lens! Which is also correct, since nothing else is advertised either. Workmanship: The entire adapter is made of metal and makes a stable impression. The EF / EF-S lenses are very tight and don't wobble. The mount for the Samsung bayonet has a very small scope that can be safely ignored. Detaching the lenses works without the lens getting stuck anywhere. Application: Since no electronic data is exchanged, focusing is done manually. The focus help on the Samsung camera is activated with the OK button (Samsung NX300M), a small image section is enlarged and the "sharp edges" are displayed using the focus peak. The aperture is either always the open aperture or you set it beforehand on the Canon camera (choose aperture, press aperture preview button, remove lens) A somewhat cumbersome way. It's definitely more fun with completely manual lenses like those from Samyang or Walimex. But if you are comfortable with working with an aperture, you can have a lot of fun. Tested lenses: EF-S 18-55mm IS II <- OK EF-S 55-250mm IS II <- OK EF 50mm f/1.8 II <- OK EF-S 10-18mm STM <- Doesn't work because manual focus only works with an electrical voltage Conclusion: The adapter does what it promises. You can't expect much for 17 euros. I will definitely use it more often. If you can overlook the hurdles (aperture, focus), this adapter is definitely recommended. If you just want to take photos, you should stick to the original Samsung lenses. Attachment: Product photo and an example picture I made in the garden on the fly.

When I ditched my Nikon and switched to the Sony A7IV, I chose this adapter because of the amount of Nikon lenses I already had. Primarily for my Nikon macro lens, on which I focused manually most of the time anyway, it doesn't bother me at all that the adapter is manual. Money was clearly saved here by saving myself the Sony macro. The adapter sits well on the camera and lens, so it fits extremely well and looks sleek. A Nikon lens on a Sony body is always an eye-catcher. The aperture ring is of course also manual and does not tell the camera what aperture level you are at. In the metadata of the photos, it simply shows F--. So you have to develop a feeling for which aperture you have just set. I did notice a little more Cromatic abortion, but that can be quickly remedied in Lightroom by selecting the lens. Images are sharp and the adapter has no downsides other than adding some length to the lens.

the question was whether the dolle adapter from sony was worth it to pack my old minolta-compatible ones onto the @6000. the answer: no, it's not worth it, the thing is outrageously expensive for what it can do. so the K&F part had to come from. all af-s become more or less stupid fully mechanical lenses. but with a zebra and a magnifying glass, it shouldn't be rocket science to work with it, unless you have nothing but snapping in mind. an aperture control is also on it, so if you're already out of the automatic mode, you should be able to cope with it and take entertaining photos. the respective bayonet connections are quite tight, tighter than sony imagines, so they also have zero play. is this a permanent solution? no, definitely not, there are still one or the other e-lens coming along. but until then the old minoltas can be used wonderfully. and there is also an a-68 lying around, for which i need the existing stuff. Addendum: Whoever had the outrageously expensive adapter from Sony on it, which ultimately only loops through the lens data and doesn't get anything right, either nothing happens at all or it bangs forever, but it costs a lot, take the k&f right away....

I bought this adapter for the Lumix G70 - to use the lenses of my Sony Alpha 58 (A). It works wonderfully! Also the manual adjustment of the aperture. What I don't like so much is that there is a circular groove below (contact between A-lens and adapter), the contact goes over the chip of the A-lens and could "easily" damage it. Maybe a production error.

For the price you can't complain. I use the lens on my Sony A7S2 with an adapter and I find the imaging quality very good. It's also good for videos to be easy to trade. A little tinkering with the software and the results speak for themselves. The processing is good I am satisfied. I can recommend it.

I think it's a well machined adapter that works very well.. I tried it on a M42 35mm and a 135mm lens .. I was surprised at the quality of images I was able to get on my Sony A7ii and Sony 6000... Well worth the investment.
