Promaster 2378 Kiwi CA FD 轉 Sony E

The aperture control ring with its on/off function is a game-changer for adapting my old glass—no more guessing f-stops. It locks onto the Sony body with zero wobble, which matters a lot for video work. Perfect fit for breathing new life into those Canon FD lenses.

Finally, an adapter that lets me use my Canon FD glass on my Sony body without losing the aperture control. The clickable aperture ring works perfectly and feels solid.

I've been using this adapter with my old 50mm FD lens, and the aperture control ring lets me adjust f-stops smoothly even on the Sony body. Build quality feels solid, and the lock mechanism keeps everything secure. Perfect for giving vintage glass a second life.
