I've been playing with an xt1 recently and love the camera's feel. I did however notice ghosting in the viewfinder from bright objects such as a window. When looking through the vf you can actually see a secondary image of the same object just off center. I thought this was a flare at first, but when taking a pic, the image is still visible in the vf. I haven't uploaded to see if it replicates in the actual raw/jpg, but doesn't seem to be when looking at the LCD. I can even read some data "burned" in the viewfinder after taking a pic. I never noticed this when demoing a graphite version, so maybe it's a firmware fix. It's pretty annoying.
