Hmmm? Yongnuo is just copying others.

There have been adapters for Sony E mount to put Canon lenses on for years, even before FE was around. Even with optics which gave NEX cameras the wider FF view with the lenses.

 

AF, aperture operation and IS all were possible with those way before Yongnuo copied them. I do not get the "even tll" part, TLL is "through the lens".

I was also thinking that AF adapters have been around for a long time, but AF performance has only been getting interesting with the 2nd generation A7 bodies. I'm sure I posted similar in the past.

Isn't TTL a reference to flash metering? Not my area so can't take it further...

TLL flash metering is the camera's business, it doesn't care much about which lens is there. TLL flash with focus distance metering also takes what the lens reports as focus distance into account.

 

AF performance with the 2nd generation bodies is ok with some, not good with other lenses still, from user accounts.

Recent adapted AF might not be like native performance in all cases, but it is still a significant improvement over earlier ones where technically it was AF, but the experience was not really useful.

Didn't know such adapters already existed. But it's good using lenses on other mounts with AF
