A friend of mine has used KF K&F Concept's camera adapter, it fits very well and the quality is very good, I will try it too

Fits really well, creates a nice solid mount with little to no loose connection ensuring focus pulling is never shakey

Excellent product. Very good value. A great way to bring new life to an old lens. I am impressed with the quality of the K&F Concept and the service I received.

I recently purchased the K&F Concept Updated Nik to Sony E Adapter for my Nikon Nikkor AI/F mount lens and Sony A7r II camera, and I must say I am extremely satisfied with its performance. Unlike the previous converter I owned, which didn‘t work due to being an older version, this updated adapter has exceeded my expectations.
First and foremost, the compatibility of this adapter is outstanding. It seamlessly connects my Nikon lenses to my Sony camera, allowing me to utilize the full potential of both systems. I no longer have to worry about compatibility issues or purchasing new lenses for my Sony camera.

The build quality of the adapter is exceptional. It feels sturdy and durable, providing a reliable connection between the lens and the camera body. The mount fits snugly, ensuring there is no wobbling or movement that could affect image quality. I appreciate the attention to detail in the design, as it truly feels like a high-quality product.

One of the standout features of this adapter is its manual control functionality. It allows me to retain full control over the lens, including aperture adjustment, focus, and depth of field. This feature has greatly expanded my creative possibilities, as I can now use my favorite Nikon lenses with the flexibility of manual control on my Sony camera.

In terms of performance, I am impressed with the image quality I have achieved using this adapter. There is no noticeable degradation in sharpness or clarity, and the colors are rendered accurately. I haven't experienced any issues with autofocus or other technical glitches, which further demonstrates the reliability of this adapter.

Lastly, I would like to mention the excellent customer service provided by K&F Concept. When I encountered an issue with my previous adapter, their team promptly addressed my concerns and recommended this updated version. Their willingness to assist and ensure customer satisfaction is commendable.

In conclusion, I highly recommend the K&F Concept Updated Nik to Sony E Adapter to any photographer who wants to use Nikon lenses on their Sony camera. It offers exceptional compatibility, robust build quality, precise manual control, and outstanding performance. With this adapter, I have finally been able to fully utilize my Nikon lenses with my Sony A7r II, and the results have been fantastic.

Works without problems.

Pretty simple product that does the job of adapting Minolta lenses to work on Sony e-mount cameras. If you're looking to do that sort of thing, this adapter is a great choice! Feels like a quality product that should last for a very long time.

Well built adapter, with mounts without play or hardness, in my case the M42 thread was not well aligned with the upper focus mark of the lens but it is quickly solved with the 4 allen screws that hold the "silver" metal thread on the sides, if you do not have the necessary tiny allen key, as in my case, you can use a torx screwdriver that fits well that loosens and tightens them without any problem, a small assembly fault, but sometimes it can be good to be able to adjust this turn, such as when using extension rings or similar cheap accessories that probably are not perfectly calibrated. The assembler on duty was having a bad day, he stays with 4 stars for "craftsmanship".

Great product and shipping was fast sooner than I expected

It's a little pricey but worth it since buying new lenses cost way more! It even has a dial to manually adjust the aperture. Mix of metal and hard plastic build. Great buy!

I'd highly recommend it for people looking for the same.
