I would like to attach a 2x yellow filter to my 35mm f2 Asph black Summicron. I would like to buy B&W. Though expensive, they seem to be the best quality - no point in putting rubbish on the front of this lens!
The filter thread is described as E39. Is this a standard thread pitch, or is Leica the only company to use it so that the consumer has to buy just Leica filters? I assume that the E39 means 39mm. Has anyone any experience of B&W filters?
