A question about IR filters   Ive 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 IRfilters 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 theres 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
