September 16, 2020 – San Francisco, California – Breakthrough Filters today introduced an all-new EF to RF filter adapter, making it the first non-Canon EF to RF drop-in filter adapter. The new EF to RF Drop-In Filter Adapter will start shipping on November 16th and is available for pre-order here.
The all-new EF to RF Drop-In Filter Adapter delivers a number of new hardware improvements including Autofocus, Image Stabilization, full EXIF support, all-metal construction, dust, and water-resistant weather-sealing, and a detachable tripod foot for mounting to ballheads, arca plates and other mounts.
Breakthrough Filters is selling the new drop-in filter adapter for $199, and the first 500 units ordered will receive an X4 Clear for free.
Breakthrough Filters is also doing a buyback for the standard Canon EF to RF adapter ($69) as well as the Canon Drop-In filter adapter ($149) with details on their website about how this works.

I think the only thing on this list that the Canon does not include is the detachable foot. And I’ll bet the AF works better with the Canon one.
I could be wrong, but I think these adapters (both Canon and third-party) simply provide the metal contacts to connect lens contacts to body contacts. There is no processing or circuitry in the adapter itself. As long as the contacts touch firmly, AF should be exactly the same, regardless of the adapter maker. I guess it's possible that Canon does have some circuitry to tell the camera that it's made by Canon so that if a third party adapter is attached, the camera dumbs down the AF, but I highly doubt it.
Anyone know for sure?
EDIT: Looks like you answered my question as I was posting it. Thanks, juststeve!
The standard and control ring adapters don't have glass, though, so...what's the deal?
I'd be tempted to remove the glass from the clear filter so I don't have anything that could reduce image quality from the lens...
If you haven't bought one yet, then you can get their version cheaper. And even then get credit for your basic adapter. Then once you have it, you'll probably buy more filters....

I think I'd also prefer a blank filterless holder just for sealing. Whilst having glass reduces focus change, I'd not mind refocusing but YMMV
If anyone's curious, here's a short look at using the adapter with a TS-E17mm. BTW Has anyone actually checked the electrical connection between EF and RF on the basic adapter, since the number of pins is different?
Only for lenses designed with drop-in filters ( like big whites ) in which the filter acts as a dust-cover for the rear lens element.
For other lenses there is no need for a glass filter. In fact you'd be better without one on account of the optical defects it could introduce.
I think it was in an interview with Rudy Winston where he mentioned that the adapter is slightly different from the others to account for the extra glass you're introducing. I wonder if that can actually be measured at home with callipers.
for real? yikes
I want an EF to RF adapter and would prefer having options but hte cost + the canon solution needing to have a filter always in made me hesitate... this seems to fit the bill, but haven't heard if its any good.
would love a polarizer and ND.. but wasn't clear how much the adapter itself is, just the filters.
The new adapters from canon do offer an polarizer or an ND. So I ordered it. But you need another 100 Euro Filter (clear) to use this adapter as an normal adapter and not only with the polarizer indside. And the clear filter has still not arrived. So an very expensive system for me. (BTW because of this missing clear filtert, another adapter had to be bought). Expensive again. Now I own three adapters - I got the third one as an giveaway.
But my question to breakthrough-photography - that had not be answered by now - is, if I need the breakthrough adapter to use their filters. An shop answered my question and adviced to buy the breakthrough adapter. Not good, as an non-geniune adapter always has the danger not to work like the genuine one from Canon.
BTW: The 200€ polarizer drop-in filter is optically dark and working well, but the wheel is smooth and the postion changes easily. There my older prime 52mm drop in filters for the 600 II and 500 II are better constructed. too bad...
