Sony have just released a firmware update for the PMW-200. Click Here for a download link.
One of the key features of this update is the ability to automatically adjust the cameras back focus. This will be great news for the few users out there that are reporting slight focus shifts when zooming. The design of the Fujinon lens used on the EX1, EX1R, EX3 and new PMW-200 means that if the camera is bumped around, say in transit somewhere or during delivery shipment the back focus can get misaligned. The auto flange back adjustment operates by placing the camera at least 3m (10ft) from a wall with patterned wall paper or a flat brick wall (something with a texture or pattern the camera can focus on easily) or a Siemens Star chart. The camera must be square on to the target. Then execute the FB Adjust option in the menu to run the calibration routine.
The next new feature is the ability to add the CBK-WA01 WiFi adapter to the camera for remote operation from an iPhone, iPad or Android device (although I have not seen the matching app for this yet). Finally there is now the ability to save the camera setup to a USB memory stick.
