[QUOTE="dbhostler, post: 17672, member: 799"] Now that's an idea, you could point the binocs, scope, whatever, toward a blank white wall and place a flash meter up against the rear lens, maybe block out extraneous light with a piece of black tape, pop the flash and take a reading. Simple. Compare all readings and this will tell which lets in how much light. Most flash meters will read in EV as well as f. For a control, you simply pop the flash and take a reading. This should give a relative reading on any optical device. db [/QUOTE]
