I almost never shoot above 1/125th with flash and can't imagine too many scenarios where I would need high sync speed for my work. Other than sync speed, any non-obvious reasons why one would want to buy leaf shutter (CS) variants of Leica S lenses. For instance, are the CS versions of the lenses better made? Are their AF motors less likely to fail? Is their some unadvertised optical difference?
Thanks in advance for any thoughts.
(P.S., I'm up to speed on the threads about rampant AF motor failures in general on the S lenses, and folks' bad experiences with Leica customer service.)
