Is there some historical reason we have 8x42 or 10x42 as "standard?" I get 7x50, 7x42, 7x35 with exit pupils of 7mm, 6mm, 5mm or 10x50, 8x40, 6x30 all with 5mm exit pupil.
Cool thread Alan,
Do you guys think that the little ones will ever be so homogenous? It doesn't seem like the full-size compacts are as far along in this process. I mean, there are a lot of 32 mm and a lot of 30 mm still out there on the market. Do you think that one day it will be almost exclusively 32 mm?
Maybe it is all marketing - a way to set apart a manufacturer's top-of-the-line from their mid-range. Swarovski has 30 mm CLs and 32 mm ELs. Nikon has (or had?) 32 mm EDGs and 30 mm Monarchs.
Alternatively, though, Leica has 32 mm Ultravids and Trinovids. Same with Zeiss, 32 mm Victorys and Conquests.
Are the differences between 30 mm and 32 mm enough to justify both? Does anybody own and use both for different situations? I get that the 30s will be slightly smaller and lighter and the 32s will be slightly brighter. Are those differences big enough to warrant both models?
