Breakthrough Photography Announces Drop-In Filters for Canon EF-RF Adapter

The first third-party drop-in filters have arrived for Canon’s EF-to-RF filter mount adapter. Take your pick!

Breakthrough Photography has announced an extensive new line of drop-in filters for those that are adapting EF-mount lenses to RF-mount cameras using the official Canon Drop-In Filter Mount Adapter. The San Francisco-based company is offering filters in every category from neutral density to circular polarizers to clear, infrared, night sky, black and white CPLs, and variable NDs in kits or individually. Both their CPL and variable ND filters are competitively priced against Canon’s own versions, $129 vs. $250 and $129 vs. $360 respectively.

The new drop-in filters are dust and moisture resistant and feature rubberized grips for better handling taking them in and out of the adapter. A large adjustment knob is used on the circular polarizers and variable NDs for easier control and fine tuning. The filters are clearly labeled and color coded to easily find what you’re looking for among a group of them. Kits come with a case that doubles as a neutral gray card.

For more information on these new filters including transmission and color cast comparisons check out the Breakthrough Photography website. The new filters are expected to begin shipping in September 2020.

This is an awesome idea... but it only works if you're adapting EF glass to the RF mount.

You can kiss this functionality goodbye when you use Canon's amazing native RF glass.

I wish manufacturers would just build ND into the body... on top of the sensor or whatever...

This adapter would be the only reason for me to switch to the R5 haha! (considering all the good quality EF glass that I already have and don't plan to change to RF any time soon)

And some people think EF glass is the past...

does anyone know if you can still use autofocus with this adapter, or is this manual focus only?

It should. My EOS R has no problem AF'ing at the darkest setting of the "official" VND filter.

Has anybody tried those VNDs? The original VND has severe blue color cast.

Never tried these in particular but I’ve been using their ND filters for years and they have zero noticeable color cast...I ordered the VND drop-in for my EOS-R the minute I found out about these.
