I have a Leica 90mm lens mounted on an X-PRO2 using Fuji's M-mount adaptor. This is a manual focus lens that is uncoupled to the focusing mechanism of the X-PRO2, so I do not expect that the brightline rectangle in the Optical Viewfinder (OVF) will move to correct parallax the way it does with a Fuji lens. However, what I see in the OVF is not one but two brightline rectangles, both being the correct size for a 90mm lens. But one is brighter than the other and it also shows the small focus area. The dimmer of the two 'brightline" rectangles is offset from the brighter one, shifted down and to the right by about 10 percent of the dimensions of the rectangle. When I actually take a photo and compare it to these two brightline rectangles, the dimmer of the two is more accurate. If I frame with the brighter rectangle, some of the image on the left and top is cut off. A Fuji fellow at US Fuji could reproduce the problem but did not know what caused it. It looks like a bug to me, hopefully one that can be corrected in a firmware update. As I pointed out to the Fuji guy, the brighter frame serves no useful purpose at all. The viewfinder should simply always display the dimmer rectangle, which is the more accurate representation of what the camera actually sees. What are your thoughts on this?
