Joel Pierre Posted November 19, 2012 Share Posted November 19, 2012 Hello. I would like to mount on a Elgget f:1.5/13 mm C-Mount, a filter and a hood, but I do not know what is the exact diameter of the thread of the filter mount. It is between 42 and 43 mm, but it is not 42 or 43 mm. This is obviously in inches. Do you know what is the exact diameter in inches ? In advance, thank you for all informations.

Phil Soheili Posted November 19, 2012 Share Posted November 19, 2012 Well, if you measured it and the result was between 42 and 43mm - which translates to 1.6535 and 1.6929 and the exact middle of that being 1.6732 - I think you may easily leave it to chance whether you'll find a 1.66 or a 1.67 filter first. I cannot really imagine that in the "Elgeet times" there could have been reliable filter thread measures other than these (that is with two digits behind the 'comma'). Cheers, Phil Link to comment Share on other sites More sharing options...
