The OWL Canon EF to Sony E-mount adapter is available now in Canon EF to Sony E-mount. This is NOT an electronic lens adapter so don’t believe you can adjust the aperture of an EF lens – this would seem to make more sense for Nikon F legacy lenses with an aperture ring.

A7R II, this drop in filter adapter and the Canon 11-24L ……………nice!
Very cool adapter. I don’t have any Canon lenses at the moment. I am guessing that the OWL folks are working on making them for other brand lenses?
Yes, in fact they’re actually much more useful in lenses with an aperture ring
Wow! I diffidently need one of these.
Are polarizing filters available? If yes, how do you rotate them? This would be great for my Canon 17 TS lens on my A7r and soon to be A7r ll system.
You can use any 52mm filter as long at they are thin enough. You’d probably have to remove the filter to rotate. The bigger issue is since this is not a Smart Adapter, EF lenses would be wide open. While that’s fine for certain uses, that may not be what you’re after with a 17 TS.
I know this is an old post, but I came across it when searching to see if anyone had developed an adaptor with a drop-in filter. It solves so many problems, but namely the issue of using filters on lenses with bulbous front elements.
I’d love to see Metabones take this idea and add it to their adaptors.
You don’t have to remove the filter to adjust a CPL. There is an adjustment wheel on the outside of the filter holder. You can see it being adjusted at the 1:34 mark in the video.
How thick is the adapter? if it’s over an inch it won’t work on my Zeiss 15mm 2.8 classic
It won’t focus to infinity if it’s over a inch thick, where can I get the thickness measurement?
ALL Canon EF > Sony E-mount adapters must be 26mm thick. If your Zeiss 15mm 2.8 classic fits on Canon EF cameras, that’s the correct depth. If your lens does not fit on Canon EF – you need an adapter for the correct mount.
