On the OM-D EM-1 (and possibly other models), the viewfinder comes in three "modes": mode 1, mode 2 and mode 3. Mode 1 is, in effect, an exact replica of the rear screen display, filling the whole viewfinder with the image and overlaying data on top of the image. Modes 2 and 3 (which are identical to each other in all but colour) show the image in a smaller space in the middle of the viewfinder, and the data area (black in mode 3, blue in mode 2, if I have remembered the numbers correctly) at the bottom. My initial reaction to this was that it seems a terrible waste not to use every pixel to display the image, and that mode 1 was the only sensible option. However, on reflection, I have now switched to mode 3 (smaller image, black data area). The EVF on the EM-1 is so large and overengineered that not all of the space is actually needed for the image. I was quite happy with the size of the image on the VF-2 when I used to have one of those to use with an E-P3. It is actually far more useful to use that extra space to keep a clean image area, I find, and have the data displayed separately. Additionally, it is much easier to see the corners of the image than when it fills the whole of the EVF. I should be interested in others' thoughts on this topic.
