The photo attachment is essentially a housing holding a partially silvered mirror that splits the beam sending enough to an eye-piece (about 60/40) so that the field can be observed and focussed. Its quite a simple but elegant solution - designed in Dr M�llring's lab at Zeiss (Oberkochen). It first appeared about sixty years ago. Variations have been made by different microscope manufacturers ever since. The camera screws on the top (Mount adapter K) and the viewfinder should be blocked so that no light can contribute to the exposure reading. Once the prism viewing screen has been set there is no need to focus using the camera screen again.
To get into light microscopy, of any kind, you need to make a rather large investment and its a lot easier said that done. Unless you have some experience there will be a very steep learning curve. I'll take a picture of the contraption some time and post it so you can see what it all looks like.
