Dear flexers, I'm passing you (as suggested by Doug Herr) my newly discovered findings on the Leicaflex SL viewfinder: I have just recently discovered another virtue of the SL: the magnification of the viewfinder, combined with a 50mm lens (summicron, in my case) gives * identical* magnification and brightnes as the naked eye. In other words: it is very easy to use both eyes open when composing a photo. With some practise, you see *one* 3D picture, and a undistracting black frame (the viewfinder). And because of the nature of the microprism (a split prism would be a distraction), it is very easy to focus in that way, too. Of course, this only works with a 50mm lens. I somehow believe that the magnification and the viefinder arrangement was done with this practice of taking photographs in mind, yet I have not noticed anyone would mention that. Have anyone else noticed this? Best regards, Miha
