This Sony E-mount camera adapter ring is sturdy and fits Nikon lenses perfectly. It's highly recommended for those of us who have those old analogue lenses but from unbeatable quality you'll obviously have to focus manually but it doesn't matter the good quality of the old lenses makes up for it. say trouble, I recommend this adapter brand K & F to everyone, thanks.

What went in the trash was a P/K mount lens, so I bought it to use. This can be worn on the lens, not the camera body. It's not a camera that allows you to use a lens; she uses a lens with a camera. I was curious about the other reviews. There are always more lenses I want to use, so I think I'll buy more.

It allows me to mount m42 mount lenses on my Nikon 1 camera...there is no auto focus with it but it is very easy to get sharp photos...there is no glass in it so the optical quality of the lens used is not affected...this unit easily connects to my nikon one and my m42 lenses...the helios44_3 and the volna9...easy to screw on and off the adapter...the package is a week early arrived than expected and the price was amazing...this was one of the best values I've bought in a long time

Can easily adapt old FD lenses to the RF mount. Fits!

First impressions: - good looking - fine workmanship - matte interior finish (light doesn't jump in) - smooth conformance to camera body - smooth shift rotating One ring - comes in an unsealed hard case and nothing else on it - out of the box with any vintage Nikon mount usable lenses - orange ring gives the looks to the whole camera setup - the adapter fits harder on the lenses (needs to be attached) - focus is based more on the depth of field (FOD) difference in the picture frame - it works more like zone focusing and precession focus zones are heavy to reach - metal mount on lens side and (I think it's still a metal) black plastic which looks nice, camera charcoal mount (it's passive adapter and therefore no electrical communication between lens and camera) - light doesn't get through the adapter into the Barrel (sealed fit) - it should come with end caps to the adapter to keep dust out when not in use - for the money I paid I like experimenting with my old lenses on the Sony mirrorless body

This is a great mount for lenses that have a built-in manual aperture adjustment, not the best for AF lenses.

Analogue lenses have character and charm - that's for sure. And they are often many times cheaper than their digital counterparts. So why not adapt the good "old glasses" to a new camera? I already own the Neewer adapter for my Minolta glasses and now I wanted to test this K&F lens adapter for my M42 lenses on my Sony a7III and a6300. Today I also added the Minolta(AF)-NEX adapter to continue using my old Sony A-mount lenses.

I placed particular value on the following two points: quality and function.
1. Quality:
At this price (Minolta AF or Sony A-Mount), you can expect a little more from a lens adapter. To get straight to the point - my expectations were fully met.
Packaging:
The adapter arrived very well packaged and, in contrast to the Neewer adapter, even has a resealable plastic box. In this you can transport or stow it very well when you don't need it. Because we definitely don't want too much dust getting into the adapter and then into the camera.
Adapter:
The K&F adapter is made entirely of metal (brass and aluminum + a few steel screws). It feels very high quality and you have the feeling of holding something solid in your hand. The thread is very clean and well made. My lenses could be screwed in and unscrewed again without jamming. That's the way it has to be!
The fit on my Sony a7III with E-mount connection was very snug and tight. There was no wobbling or sliding after the adapter snapped onto the camera. It was also easy to dismantle thanks to the grooves on the surface of the adapter. This was thought through and not just valued for the optics.
The aperture selection on the Minolta AF adapter works excellently and feels "full" and easy to use. The f-stops therefore sit correctly and are not accidentally adjusted.
2nd function:
The adapter actually only adjusts the back focus of the "old lenses" to the new camera. He does this job excellently! Focusing to infinity works perfectly and the images are not affected by any additional lenses. Of course it depends on the lenses what the end result looks like - in my case I have the Porst wide angle 35mm f/3.5, the Auto Exaktar 135mm f/2.8 and for the Minolta AF the Samyang 16mm T2.2 used (see sample images).
I'm really happy with the K&F adapter and I'm sure I'll still have a lot of fun with it and my old lenses. I would buy it again anytime.

Edit 03/04/2019: I've even bought the Minolta(AF)-NEX adapter because I've only had good experiences with the products from K&F so far and I wasn't disappointed this time either. Great product and thanks to the choice of aperture I can now continue to use my old Sony A-mount lenses.

I bought and paid for the K&F adapter as usual via Amazon, but I get the money refunded as a product tester. As always, my opinion remains independent and honest.
