Hi guys I have a 77mm ND fader (which I use on my DSLR) and want to use it on my EPL1 when I go travelling. The issue I have is that I cannot find a 40.5mm - 77mm step up ring to allow me to do this. The largest step upring I have found is 40.5mm to 52mm. So, is it possible to use a 40.5mm - 52mm and then stack a 52mm - 77mm and use th ND fader that way? Or, does anyone know where I can get the step up ring I am after? I don't really want to buy another ND fader. Cheers inadvance.
