[QUOTE="typo, post: 3145581, member: 83808"] After a dull and wet morning the sun finally came out at 3:15 and I had about 10 minutes before the sun dipped behind the houses. No time to set a new distance so it was 28.5m again, but the light levels were about double Sunday's level and only just below my optimum. Tripod mounted, pattern 0,1 @ 28.5m which gives 7.2" (apparent VA 72"+) Hand Held, -1,4@ 28.5m which gives 10.2" (apparent VA 102"+) This was actually the same as I recorded Sunday but this time it was en easy read and I was very close to the next pattern for both readings, hence the "+". Vanguard Endeavour EDII 8x42 Tripod Mounted, pattern -1,6 @ 28m which gives 8.12" (apparent VA 65") Hand Held, pattern -1,3 @ 28m which gives 11.5" (apparent VA 92") I said at the out-set that I chose these two as I thought they represented two different levels of steadiness in my hands. Interestingly in both sets of readings the hand held were 42% worse than the tripod mounted for both binoculars, and for the Prime at least, worse than I'd previously measured. I needed to rush about to get the test in which may have played a part. I would still say the amplitude of the shake was higher in the Vanguard yet I was still able to get a relatively better apparent VA, which surprised me. The Prime probably has the higher and more neutral transmission, but the Vanguard better perceived contrast might have just edged the results in it's favour today. I somewhat doubt the Vanguard's small resolution advantage would have contributed to today's result. David [/QUOTE]
