中古 Sigma Mount MC-11 Canon EF-Sony E マウントアダプター (#54104543CM)

Was a bit nervous buying used, but this adapter arrived looking barely touched and works perfectly. My Canon glass locks onto focus fast with my Sony body, no lag at all. Glad I saved the cash over a new one.

Autofocus snaps noticeably faster than my old adapter, and the metal ring feels solid even though it's clearly been handled before. The used condition was honestly better than I expected — no scratches on the glass or looseness in the mount.

I was worried buying used, but the mount feels solid and the AF on my Tamron 24-70 is just as snappy as on my old Canon body. No play at all when connected.
