However, a lot of Fujinons are also equipped with this feature,

 

With a little twist though, most of the wide angle Fujinon primes have a focus distance scale on the lens and they match the distance as you turn the ring. Which means they behave just like a conventional lens.

 

Also, I never really had any problems with focus by wire neither. It actually provides much better adjustment as it moves slowly the slower you turn the ring on Sony lenses.
