Hello.
I'm really interested on this lens.
However, I'm concerned with a review on B&H website which says the OSS stabilization system will not work with the Sony A7R.
The reason, as stated by the reviewer, is "the SteadyShot mode is permanely turned-off in the latest firmware because Sony recognizes that the shutter vibration problem interferes with the OSS. Therefore you CANNOT use the OSS with the A7r".
I'll be grateful for some reports on the subect.
Joao
