Thanks Steve for the explanation, i was more referring to the FF pentaprism size (.75x 100%) versus APSC (.95 x 100%) and probably should not have mentioned aperture. My apologies for wording the question badly. I believe that binoculars perform better with larger aperture lens than versus smaller lens at relative magnification and i thought this would also apply to pentaprism as well.

I worked out that FF vs APSC is about one stop difference in apparent light, if my math was correct. Have to go now. cheers

With the larger aperture/size viewfinder the scene should be brighter this should make it somewhat easier to focus manually. Can anyone with K1 currently confirm this please or give opinion? I didn't read every post here and now see Monochrome has asked the same question. thanks
