Message: <blockquote data-quote="typo" data-source="post: 3144033" data-attributes="member: 83808">The rain we've had for a few days has stopped and after a very foggy start it cleared after lunch and I tried a few readings. The ambient light (needed to contract the pupil) and target illumination (contrast) where way below what I would normally use for testing, but with little prospect of an improvement in the next few days I thought I'd post the results anyway.I initially used 10.5m, but the light (and results) improved a little to about 2000 lux when I had moved the chart to 28.5m and it's those I'm reporting. I used two binoculars, my Zen Ray Prime 10x42 which I consider one of my steadier pairs in my hands and also my Vanguard Endeavour EDII 8x42 which I don't find so steady. In previous boosted test results the Vanguard gave slightly better full aperture and stopped down resolution results than the Zen Ray, but I would not expect to see any difference at these light levels.Zen Ray Prime 10x42Tripod 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")I should say that I felt I was struggling with the light levels and taking longer to decide a reading than I normally would, though still kept within the minute Kimmo suggested. The Tripod mounted apparent VA is about what I expected but the hand held is worse. This works out as a 42% decrease in apparent VA which is a rather larger difference than I've previously seen for this binocular.Vanguard Endeavour EDII 8x42Tripod mounted, -1,4 @ 28.5m which gives 10.2". (apparent VA 81.6")Hand Held, -1,1 @ 28.4m which gives 14.5" (apparent VA 14.5 116")This again works out as a 42% decrease in apparent VA which is only a little more than I've seen previously. The light had dropped a little more by the time I did this test.I intend to repeat this, if or when we get better weather.David</blockquote>
