Don, use www.tinyurl.com when you have long url's like that. Try it,
its really cool, it converts them to "tiny" urls that go to the same
page and do not need copy/paste.

Not that big a deal Cotty, it's also called a "semi-silvered" mirror.
Lets some light thru, reflects some.
A lot like the "one way" mirrors you've seen.
Here's a page on the Canon F-1 that shows some advantages and disadvantages:

Here's one from Edmund that shows a Pellicle "beam splitter", works the same
but has superior qualities.

Sorry about the long URL, you'll have to copy and paste it.

On 17/8/04, fra, discombobulated, offered:
I am more thinking that with increasing sensor sensitivity, we could
see a pellicle mirror DSLR. Imagine it - very fast, very quiet, no
dust on the sensor,... Is it possible to have AF in pellicle mirrror
one? Where would be the sensors?
Can anyone recommend an easy to understand web page that explains how a
pellicle mirror system works, so a thicko like me can get my
noggin around it?
Cheers,
Cotty
