Sorry it took so long to answer. Really busy weekend......:king:
I hadn't used the 7x42 UVHD+ for quite a while (it is set for my wife), but I just tried it's focus wheel earlier this evening. For the most part, I could not discern any hesitation/backlash when changing focus direction. I say "for the most part" because every now and then I thought I could discern just the slightest amount of backlash, but it was extreeeeeeemly small, if present at all. Overall, picky as I am, I think the focus wheel works just great.
Thanks for the response, Phil. I think I would describe mine in the same way. I have noticed that an extremely small amount of slack or backlash is sometimes noticeable when and if I suddenly change focus direction. If I focus to a certain point and then move the wheel in the other direction after a pause then I feel no slack at all. If I gently 'wiggle' the focus wheel clockwise and then anticlockwise with the first two fingers of both hands together I can feel that it's not 100% 'tight', but in practical terms the slack is only occasionally noticeable when suddenly changing direction with one continuous movement while focusing.
I very much suspect that all UVHD and UVHD+ bins are like this (although some might be slightly worse than others within certain tolerances) but that some people are much more sensitive to the issue than others.
Inevitably, I suppose, there will be a few examples which may be outside of normal tolerances which find their way into the hands of very critical users (like me! ). Those instances deserve to be dealt with in an understanding and professional way by Leica.
