The problem is they cut heavy corners on all new fast primes. The supposed top of the line 24/35/85 f1.4 lenses uses lower cost micro motor with set of plastic gears. The form is exactly same as canon's notorious EF 50 1.4: Micro USM, geared FTM, lots of tolerances. The results are the same too: inconsistent focusing, especially in mid-far distances.

This corner cutting is blowing themselve back like a jammed rocket launcher, BAMMMM!!!

This is patently false information. They do not use "micro motors with plastic gears." They are ring motors using ultrasonic waves that convert to rotational energy to move the elements. There is no micro motor and no gear system in the 24/35/85 AF-S 1.4 G lenses. Take one apart and you will see for yourself.
