Light passthru in addiction to magnification

Postby Snakebite on Thu Nov 08, 2007 2:02 am

Hello,

can someone tell me any addictions between light passthru and magnification? The higher the magnification the lower or higher the passthru?


Cheers!

Hi

Basic law of optics - all else being equal, as magnification goes up, image brightness goes down.

Hi

Any of those will be fine - all take in as much light as your eye can use, anyway.
