ahsanford said:But why you would go to the trouble of those two things above and only put a m43 sensor behind it is nuts. Is there some Speedbooster upside to this that I am not seeing, because otherwise Yongnuo is asking you to sign up for a pricey (EF) ticket on the HMS Queen of Horrendous Ergonomics and Voluntary Crop Factors. You are getting all the downsides of FF physics/size/weight and virtually none of the FF IQ upsides.
Who would buy this?
Given that it's a smartphone attachment, the M43 sensor makes a lot of sense. Smartphone users lack telephoto reach, and by throwing an $80 Canon 75-300mm F4-5.6 III USM lens on it, you end up with a 150-600mm telephoto zoom lens on your phone that's extremely light weight.
I doubt anyone would go through the hassle of putting high quality glass on this. It would probably snap like a twig under the weight. Even though it sports an EF mount, this was pretty much designed to be exclusively used by light and cheap kit lenses.
