Clever and Useful: A Review of the Canon Drop-In Filter EF-to-RF Adapter

One of Canon’s niftiest new gadgets is the EF-to-RF mount adapter that can accept both variable ND and circular polarizing filters, allowing you to use them with any EF lens without having to worry about individual filter size, making it useful for a wide range of situations. This great video review takes a look at the adapter and how it performs in practice. 

Coming to you from Christopher Frost Photography, this excellent video review takes a look at the Canon EF-to-RF drop-in filter mount adapter. When you adapt an EF lens to the RF mount, there is extra space due to the shorter flange distance. Instead of leaving empty air, Canon came up with the clever idea to allow the user to drop in variable ND and circular polarizer filters. A further advantage of this is that because the filter is inside of the adapter instead of mounted on the front of the lens, you do not need to carry different filter sizes to fit separate lenses. The adapter is definitely on the pricier side of things, but on the other hand, if you carry multiple filter sizes in your bag, it could end up evening out. Check out the video above for Frost’s full thoughts.
