I dont like the feel, but would accept it given they are all the same. All of the pairs I tried seemed very consistent in this regard, which is a good thing I suppose. Its obviously built in as part of their design. I have noticed that a pair of Zeiss I have owned for around 10 years started out with no play, and ended up with very slight play in one direction. Some people may consider that a fault has crept in, and get them repaired. I dont at this stage. I was wondering if Leica build in the 'play' because it suits their manufacturing tolerances, and to ensure the mechanics do not noticebly change over the years for their customers - thereby generating warrantee work? Another thought i've had is that it may be to do with allowing easy operation at temperature extremes?</p></blockquote><p></p>
