Sony A7R Shutter Vibration: Mitigation Strategies
To my Sony A7R/A7 review is added a new page.
Mitigating Shutter Vibration on the Sony A7R
Interchangeable lenses are a nice thing, but my own view is that Sony ought to extend the Sony RX1R line by moving to the 36-megapixel sensor found in the A7R and offering three additional focal lengths for a wide range system, perhaps 19mm and 24mm and 75mm.
Lenses matched to the sensor are the ideal situation: they can be optimized for the sensor, and a leaf shutter is a big plus for zero vibration exposures and full flash speed sync.
