I´ve an MM2 that has developed a problem with the focussing wheel, which now spins on its axis or pin but doesn´t focus. I´ve e-mailed Opticron about it, I´m sure it´ll get sorted out eventually but as it´s the Xmas season it´ll probably take a while...I won´t bother sending it off before the New Year. I just wondered if anyone else has experienced a similar problem, and if it sounds like it involves worn internal threads or something like that. (Sorry, I´m non-technical). It´s not a matter of life and death, I´m just curious. Any advice appreciated. Thanks in advance and Happy Christmas.
