a question about ir filters i've a digimax a and i am excited about getting an ir filter well the first thing i needed to know that how sensitive my camera was to ir filters and i did a remote control test in which i saw the light very brightly so i think that ir photography would work fine with the camera the thing that bothers me is how do i install it on the camera in practice i hate it when there's no info on the internet about that and why are the sizes that i found on an online store only mm or so minimum i presume it is mounted on the objective obviously but my objective is much smaller mm to be precise thank you in advance talk
