Review: Buon prodotto. - L'adattatore fa il suo dovere. E in metallo e da la sensazione di essere sufficientemente robusto. Viene fornita in dotazione la chiavetta per svitare le tre vitine di serraggio ed allineare la filettatura con l'obiettivo qualora fosse necessario. Ovviamente essendo privo di contatti elettrici la messa a fuoco e la regolazione del diaframma sono sempre manuali. Bisogna ricordarsi di abilitare la funzione di scatto senza obiettivo sulla macchina. Ho scattato solo un paio di foto di prova ma mi sembra un buon prodotto. ## Features - Thanks to the solid full metal lens adapter, the 42mm screw mount M42 lens fits the Canon EOSR RF mount series mirrorless Ful Frame camera body. - Supports AV/M mode.

After changing the settings on my Canon R5 everything worked fine with my moms old Pentax Super Takumar 55 f2. Sharp! The adapter locks in place on both ends. Feels good. Only thing that was weird was that I ordered this and an FD adapter at the same time but the order was split - with the FD being a couple of weeks slower.
