Sony A7R II

Electronic First Curtain Shutter Vibration Assessment

The Sony A7R II offers an electronic first curtain shutter option, which all but eliminates shutter vibration (the shutter still has to close unless Silent Shutter Mode* is used*, so in theory there could still be some vibration).

The predecessor of the A7R II (the A7R) ruined a huge amount of your author’s work. Thus the addition of the EFC shutter option in the A7R II is for your author at least, the #1 feature to be gained. See Sony A7R Shutter Vibration / Shutter Shock. The lack of shutter vibration possible with an EFC shutter means that any lens like Zeiss Otus or even long teles like the Leica 280mm f/4 APO-Telyt-R can be shot with superb results and no fear of damage to sharpness by shutter vibration. At the full 42-megapixel resolution.
