This has already been mentioned in another on-going thread but the v2.0 firmware update is available to download from pro.sony-asia.com/support/product/nex-fs700 (http://pro.sony-asia.com/support/product/nex-fs700).

Just select your operating system from the dropdown to get the proper file.

This firmware update allows the FS700 zoom servo controller to control the zoom on the E PZ 18-200mm F3.5-6.3 OSS : SELP18200

I have the previous lens so it wont matter...is there any other reason to upgrade or is it only for that?
