Canon 3443C002 Reviews

Too easy to hit when shooting

I bought this for my r3 because I have lenses that don’t work directly with the camera. The drop in filter mount adapter works great but it is REALLY easy to change your settings. Which means, especially when switching to portrait from landscape or vice versa, your finger can adjust the amount of light allowed in by accident. I don’t know if there is a way to avoid that or if the dial can be adjusted to be more difficult to turn. I have never used one of these before so maybe I’ll get used to it but wow it has made me question keeping it.

Great value added for EF lens

Its a great trade off to bulking up the EF glass. Worth the money. Stop anguishing over the decision. I also think the control ring one is worth owning though.
