If I were to buy a 4x5 glass ND filter, take it to a glass cutter, and have them cut it to 4x4, would it adversely affect the filter? Would this be inadvisable for some reason, or would it work? I ask because I've had trouble finding 4x4 filters, and many other sizes are easier to find.

Just make sure it's a solid glass filter as opposed to a laminated one.
Oh and have them bevel the edge as blood on the lens does not make you a hero! lol

Ya but these are on there litteraly ALL the time. I'd just wait and keep an eye out unless you've GOTTA have it RIGHT now for a shoot or something, one'll come up AT the price you want, you'll see. No sense in f*#king up your 5x4, which is REAL eazy to do when you're cutting glass. If anything I'd see if I could rig it somehow to work as is, tape it in or something. If you absolutely HAVE to cut it, take it to a glass place and let them do it, it'll probably cost you like 5 bucks at the most, WELL worth not screwing up you filter.

Yeah definitely, that's what I meant! "take it to a glass cutter," not "take a glass cutter to it"

Oh ya, sorry, I just skimmed over your first post and missed the "take it to a glass cutter" part. If you don't have any use for a 5x4 then that would probably be the best plan. They should be able to bevel or even just sand down the edge for you as well.
