IR cut filters for M8.2
let me start by apologising asking something that has probably been discussed over and over. I just couldn't find an appropriate thread so I thought to ask the kind people here...
I'm looking for IR cut filters for my newly acquired M8.2, and to be honest, am really wondering whether I should pay the premium for B+W filters vs cheaper stuff, like tiny.cc/dn0bbw
I need to get 40.5mm filters, at least two at this point. One for my J3 and the other one to remove glass from and insert into a 40mm filter frame for my Canon 35/2 - I don't think anyone makes IR cut filters with a 40mm thread (I have managed to acquire a number of skylight filters for it and am prepared to smash the glass out of one for this purpose (I have already DIY'd myself one yellow filter for B&W film this way).
With many thanks,
