[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Recently there was some discussion about replacing older Leica lenses with flanges that have pre-divoted indentations for 6 bit coding.. I stated there were 5 and 6 hole patterns. I need to make further clarification.. There ARE 6 screws in Leica M lenses. However, there are 2 hole patterns. One of the patterns allows for the replacement flange to be fitted and use all 6 screws. The other pattern, has a screw right where the 6 bit codes are.. So upon replacement, only 5 screws are used. I do not know what Leica does about this dilemma, but for us mere mortals, it means there are 2 different flanges to choose from. To make this easier to understand, look at this EBay ad.. USA #360389035614 where both screw patterns are shown, and you can pick for yourself which flange you will need... Frank Filippone Red735i at verizon.net
