I bought this F4 a while back with a DP20. I can't help to notice I do not like the way the finder works.
I usually like to push my eye as close as to the viewfinder as possible. However when I do it to the DP20. I find that, either I can see the Aperture on the top, then I can't see the LCD bar at the bottom, or the other way around, or half and half. Unless I hold it a little further away, play around with it by tilt it up and down till I can find both of them. My point is most of the time I can only see one and then I have to tilt it in whatever way to see the other one, that's kinda dumb.
Any of you have that problem? Or is my eye ball defective, anyone got a bigger eye ball for sale?
