I just tried a little experiment--I took my ME Super with a 50/1.4 K lens (SMC-Pentax) and my ZX-5N with an FA 50/1.4, and held both cameras vertically, one camera up to one eye, one to the other. I could superimpose the two viewfinder images and compare them. The ZX-5n finder image is only about 4/5ths as big as the ME Super's--it looks about like this: _________________ | | | | | ____________| | | | | | | | | | | | | | | | | | | | | | | | | | | | |___|____________| Hope this comes through--sorry about the limitations of my drawing program <s>. _Coverage_ relates the extent of the viewfinder image compared with the extent of the image that will be recorded on the film: _________________ | _____________ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |____________| | |_____ __________| This would be an illustration of a finder with poor coverage, assuming the inner rectangle represents the viewfinder image and the outer rectangle represents what's going to appear on the film. Eye relief or "eyepoint" is just the distance you can remove your eye from the eyepiece and still see the entire viewfinder image. This is why glasses-wearers always worry about "high eyepoint" finders--because their glasses prevent them from getting their eyeballs close to the finder eyepiece. --Mike - This message is from the Pentax-Discuss Mail List.
