I've been having trouble focussing on specimens at high magnification (800X to 1500X) and the only way I can do it is by focussing the microscope and correcting for the difference (2,5 um) before taking the picture - this is a bore and does not always work. There are very expensive solutions to this problem, but I'm out of cash right now.
I need a K mount Pentax body with a clear glass focussing screen - without focussing aids like split image or those micro-prisms. Anyone got any ideas? The ME Super I'm using is perfect in other respects as it can be used in automatic mode and reads the exposure very well. And the slow speeds are useful. Changing the screen is not an inviting prospect and would mess up a lot of other things. Even a ring of clear glass around the centre of the screen would be enough.
