Breakthrough Photography EF to RF Drop-In Filter Adapter

bt filters

A few weeks ago, Breakthrough Photography announced a new line up of Drop-In style filters for the Canon RF-EF Adapter. They have now released their own adapter for $199 USD.

The adapter has full contacts so the lenses transmit EXIF data and are compatible with Autofocus & Image Stabilisation if the camera features it.

It is compatible with both Canon & Breakthrough Photography drop-in filters.

The adapter is built from an aluminum alloy, and has a detachable tripod foot which houses a 1/4″-20 mount.

Canon Adaptor Buyback

For those who already own the Canon adapters, Breakthrough Photography is running a Buyback scheme where they will credit back $69 for the standard adapter and $149 for the Drop-In Filter Adapter.

For comparison, the Canon EF-EOS R Mount Adapter retails for $99 USD and the Canon EOS Drop-in Filter with Circular Polarizer retails for $299 USD.

Since the Canon Drop-in Polarizer would work with the Breakthrough Photography version, we would understand the buyback scheme to be just for the adapter.

$69 USD value for the standard adapter is quite reasonable, especially if you are a RED KOMODO user as each camera comes with one of these and would be less hassle than selling it yourself.

It doesn’t make too much sense to trade in the Canon Drop-In adapter since they essentially do the same thing and both take the same filters.

Pricing & Availability

The Breakthrough Photography EF to RF Drop-In Filter Adapter retails for $199 USD.

The first 500 orders will also receive an X4 Clear filter valued at $49 USD for free.

You might be wondering why you would want a clear filter, it gives you an option to use the adapter without any loss of light as any polariser would result in a loss of light transmission since you can’t use the adapters without a drop-in filter in place.

By comparison, Canon’s Drop-In Clear Filter retails for $129.95 USD

The Breakthrough Photography adapter is a nice option at $199 USD, especially if you don’t want to go for the circular polarizer, as currently the only way to purchase the Canon drop-in adapter is with the circular polarizer at $299 or with the Variable ND filter for $399.

The adapters are expected to start shipping from November 16, 2020.
