KnightsFan Posted February 19, 2021 Share Posted February 19, 2021 @tupp By software failure, I mean that if you have an existing protocol, like L, and translate to another protocol, such as EF, there is the very real chance that not every lens and camera will work. For example, Viltrox's EF to M43 adapter can control aperture, but not autofocus. Some lenses don't work at all. Adapters between different manufacturers will always have that risk. RF to EF is much safer, since the same company could make firmware updates on both ends to fix bugs that they missed in testing. I think that RF would be the only good option. E, L, and M43 would have a very high chance of failure in some combinations of adapters and lenses. I also suspect Canon isn't licensing RF to Blackmagic. As for mechanical failure, adding support screws would solve it, but would also require 1st party adapters since there is no standard for it. Z Cam did it, to their credit. I just don't know if it would really sell enough extra units to offset the cost. How many people do you really think would have bought on in L mount, but not EF? If Sony allowed it, E might have added some sales since there are numerous E mount lenses, but if you're targeting users who use EF lenses... I don't think the EF mount is a big hindrance. tupp 1 Quote Link to comment Share on other sites More sharing options...
