Therefore, check whether the lens is an APS-C-only lens or not. The fit (hard, loose, slight play, etc.) may differ depending on the lens manufacturer. 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. High precision The adapter is an important part to attach and use the lens and camera body. When attaching a lens or camera body to this product, it can be attached and detached with a feel similar to that of a genuine combination. It will be easy to put on and take off. As the number of pixels in digital cameras increases, the accuracy of the adapter tends to affect the shooting results, so we recommend a high-precision adapter that you can use. Premium Material All-metal design, hardened anodized aluminium construction; Brass Bayonets on both Lens and camera sides provide rugged flexibility, easy to mount and remove. Matte Paint In order to remove the reflection of light, an effective matte coating is applied to the inside. Careful matting treatment will bring out the original lens performance.

Review: Adding extra value and versatility to high quality old lenses. - As a Sony shooter since the A7 was first released, I also started collecting Minolta vintage (60's and mostly 70's) cameras and lenses such as the SRT, XG, XD and X series cameras and second gen MC and first gen MD Rokkor lenses. These are sensational, compact, sharp lenses with character. A lot of modern glass just tries to be sharp while abandoning any attempt to add character to the images... Both have their place of course, and this adapter allows me to pick and choose what kind of images and lenses I want to shoot on the A7RIII and A7RV digital bodies. It makes high quality vintage lenses a really good value purchase for those who want to slow things down and shoot some manual shots with some lovely film-like character. The quality of the images are more to do with the actual lens and skill of the photographer so no point giving an opinion on that. Positives: The adapter itself seems really well made, well finished and solid, and they have attempted to make the aesthetics match vintage lenses and the body itself really nicely. It does exactly what it's supposed to and does it well at a 'reasonable' price. Negatives: There is a little pin/knob which must be lifted/compressed to secure and release the lens... But this little knob is positioned on the grip side of the lens. A7 cameras can be cramped in that area anyway so having a sharp little knob there isn't the best. However, it would be even more inconvenient if it was on the other side due to manually adjusting lenses, so I guess it's mostly unavoidable. The orange band around the adapter which is supposed to match the Sony mount doesn't 'really' match. It's a slightly different colour and a different finish but it's a nice idea so credit for trying! The positives vastly outweigh the picky little negatives and I'm really glad I picked it up. 8/10 product.
Review: Highly recommend it - K&F CONCEPT, especially the PRO series, maintains a high level of product quality, with no comparison to no-name adapters. Highly recommend.

### ⭐⭐⭐⭐⭐ Use those old, sharp lenses!
*by T***R on 24 March 2021*

Fitted a micro-Nikkor 55mm 2.8 to the a6000...and what a great combination as a portable tele or portrait camera...this lens is so sharp and a bargain if you can find one. The convertor obviously means you adjust the aperture ring and shutter speed manually and use focus peaking on the camera. It seems to back-focus a bit so bear that in mind and make sure the focus colour is showing in front of your subject as well as on your subject. The Adapter is well made and will help bring some of your old glass to life on a mirrorless camera. And by the way, there are some real mirrorless bargains to be had now. Don't buy if you only have lenses with no aperture ring...not a fault, just a fact. A couple of sample tele shots included....55mm on a crop sensor, so about 70mm focal length.
