Hi Ed,
My 22x70 is definately f/6. The Miyauchi Saturns also have slow f/#'s. I agree that nearly all handheld binos are faster for the reasons above. My question was why do some of these rather expensive, high quality astro binoculars continue to use BaK4 prisms when they aren't necessary. Marketing issues perhaps?
