Promaster 微距延伸管套組 (適用 Canon RF)

The electronic contacts on these tubes work perfectly with my RF lenses, keeping autofocus fast and accurate. I've been able to capture tiny details on flowers that my macro lens alone couldn't reach. Build quality feels solid and the fit is precise.

Took these out for a test with my 100mm macro lens, and the autofocus still works perfectly, which was my main worry. The connection is snug with no wobble, and getting those extreme close-ups of flower stamen details has been a game-changer.

The build quality feels solid and the rings lock onto my RF lenses without any wobble. Autofocus and aperture control work perfectly, so I can finally shoot extreme close-ups without swapping lenses.
