MY XT-5 suddenly has a locked shutter. It's been working fine up to now. Unfortunately, I am on a trip, planned for over a year, in New Zealand. I upgraded the firmware shortly bfeore I left New York, made sure all the batteries were in good working order etc. The only thing i did today that was out of the ordinary for me was to try a panoramic shot. I didnt even finis the full shot when the shutter curtain locked in the closed position. I have pulled the battery for over an hour, turned the camera on and off, as some users have suggested and still no success. I need help or the trip of a lifetime will be just a memory, literally. Help!
