二手 Viltrox EF-EOS M2 0.71x 鏡頭轉接環 Canon EF 接環鏡頭轉 Canon EF-M 接環相機用 - 增倍器

The 0.71x speed booster on this used adapter makes my 50mm f/1.4 act like a wider, brighter lens on my M50, which is exactly what I needed for indoor shots. It arrived in solid condition, no scratches or issues with the electronic contacts.

Autofocus on my EF 85mm feels noticeably snappier than the native adapter I tried before, and the extra light from the 0.71x reduction makes a real difference indoors. Slight click when mounting, but it's solid and hasn't loosened up after a week of daily use.

The focal reduction makes my 50mm feel noticeably wider on my M mount body, which is exactly why I grabbed it. Took a bit to seat the lens securely, but once locked in, the autofocus worked fine.
