Message: <blockquote data-quote="Mike F" data-source="post: 3580936" data-attributes="member: 142462">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! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /> ). Those instances deserve to be dealt with in an understanding and professional way by Leica.</blockquote>
