Strange behaviour of X-E1 viewfinder

Unfortunately there is a "stuttering" effect seen in the EVF of the X-E1, which is due to the relatively slow refresh rate of this viewfinder. This is seen primarily when panning with the camera. There is also a slight delay causing a momentary freeze of the image in the VF when focus is achieved. This focus freeze was seen with the EVF of the X-Pro-1 as well but here it is not as pronounced. I personally passed on buying the X-E1 because of the EVF lag which I found annoying.
