EF-to-E 0.71x focal reduction lens mount adapter can combine EF series lens with
Sony E S35 movie camera or APS-C camera to reduce the focal length of 0.71 times,
improve the luminous flux, and increase the aperture by one gear. It supports
automatic focusing, automatic aperture, antishake and other lens functions.

EF-to-Z 0.71x focal reduction lens mount adapter can adapt lens of EF mount

useful for apsc R mount if you prefer EF lenses

PRO:
1) works as an EF-RF adapter and reduces the focal length multiplication of apsc sensors. EF lenses are less expensive than RF, more diverse and require less in body correction in general.
2) EF lenses gain an extra stop of exposure. For example a 70-200 EF f4L gets the light gathering power of the much heavier and more expensive 70-200 EF f2.8 L
3) Seems to have a weather sealing gasket. If you keep it on your camera, its optics prevent dust entering your camera body during lens swaps.
4) Additional control dial is handy and well placed.
5) Can use EF lenses with a standard adaptor, which would act as a 1.6 teleconverter
CON:
1) maybe some optical artifacts in some cases? None noticed so far.
2)adds a little to length of kit, but I find it helps balance a small apsc body on a longer lens.
3)background blur "bokeh or toneh" seems no better than the original focal length,
4)Camera may not report correct data for images. May also interfere with IBIS and AF speed at some apertures . Very lens specific in my experience.
5) Subject to loss of some functionality depending on camera firmware, although the adapter can also be updated.

It seems really interesting

The adapter looks really interesting, I ve a canon R7 and it may help me i my shootings. I think in the future I'll use one of these and review it on my instagram page
