I'm butting in !!!!
I just touched on these emails lightly and I remembered that the Canon
EOS-1N RS uses a special type of mirror that does not flip up to expose
the film, but sort of reduces its reflectance or something. This allows
the person to have a continuous view of what's happening even during the
actual exposure. I think they use a material that reflects 1/3 of the
light to the prism, and 2/3 to the film. The curtains then simply
control when the exposure occurs.
Ling do you know anything about this? Or anyone else perhaps? I'm
interested in this technology.
I hope I haven't side tracked too much.
thanks
