Hello guys,new to forum, just thought i would post my views on my zeiss 8x42 sf,might be of interest to someone.1. sharpness,beats my reference standards nikon se 8x32 and my leica 8x32bn,beats them easily i may add,2.fov just a fraction less than my nikon 8x30 e11,hard to spot the difference. sweet spot 80% to the edge from centre, very gradual fall off to edge.3 .colour bias very slightly warm,to my eyes anyway. 4. contrast, excellent.beat the swarovski 8x32 sv i tried it against,also beat it for sharpness and resolution.Didnt try it against the 42.The thing that will absolutely astound you is the pronounced 3d effect,the most i have ever seen in a binocular,bags more than my zeiss nobilem 10x50 porro.Makes everything else seem flat in comparison and leaves a very vivid impression ,you just want to keep picking them up and use them on anything. Like some other users have reported the focuser has a slight dry rubbing sound on use,i suspect a teflon washer or similar used instead of lube.Anyway all in all its a fabulous optical instument any one who gets one will love it.In my 50 odd years using optics from a Roland cristens apo 6 inch refractor to battleship 10x80 binoculars its the one that i know i will NEVER part with.
