Just purchased the T-X4. Within 2 days I encountered an issue that prevents me from taking any photos. It was working just fine did a couple photos shoots without any issues. Then each time I press the shutter button half way or full, the camera resets / turns off and on without taking the photo.
Reset all settings, updated firmware even though it was already on the current version. Out of luck. Super disappointing after spending $2000 on a first real camera.
