Sony A7 II @ 180mm: Focusing and Field Shooting (Leica 180/2.8 APO)

The EFC shutter (electronic first curtain) feature was enabled, for zero vibration from the camera shutter.

Following the short focal length examples (previous pages), a challenge came to mind: the Leica 180mm f/2.8 APO-Elmarit-R had been a nettlesome failure in field usage on DSLRs for years (on both Canon and Nikon). If not for missed focus (optical viewfinders with manual focus are a cruel joke at 180mm), then shutter issues and/or mirror slap. Very high failure rates.

For that matter, the 24-megapixel Leica M240 has problematic shutter vibration, rendering the 180/2.8 all but useless with the Leica R-Adapter-M, no matter how sturdy the tripod (100% failure rate (blur) at shutter speeds below ~1/125 second).
