Given the very low price, I didn't expect much––I've gone through a number of adapters. I'm thinking quality control probably varies greatly between each copy, but I was lucky that mine has worked flawlessly. The fit is secure, no play or wiggle movement––not too tight and not in any way loose.

I'm using this with a Tamron 55-300 zoom lens on an A7RII. It's a big long lens, but connects solidly with the adapter and it feels like a single piece. Focuses fine at the macro, close and infinity ends.

Excelente adaptador, se conecta firmemente tanto a la cámara como al lente, cuenta con un swich que al ser girado habilita la posibilidad de cambiar la apertura del diafragma de manera manual, el adaptador no tinen ningun elemento dentro por lo que la imagen pasa con claridad directo del lente a sensor. PRO: - Usal lentes viejos en camaras nuevas sin espejo. - Permite el control completo del lente conectado a la camara. - Hace justo lo que se anuncia. CON - No tiene soporte para tripie

I am using it to connect a Topcon Auto Topcor 2.5cm to a Sony A7RM2 body; works fine and focuses to infinity.

Perfect adapter for a manual focus lens. It does its job well.
