Hi all.. Since yesterday I've had a strangle problem with my XT-30 (1 month old, latest firmware). When I take a picture, on mechanical shutter, the image is totally black. On electronic shutter, it operates normally. If I take the lens off, I see the shutter operating as I think is normal, I've never needed to look before, but it closes and reopens... I have performed both resets, and left the battery out for about 20 hours... any ideas folks? Thanks in advance... Pete
