IR or UV cut-off filter?

I see your idea. But, nope.

Interesting thread.

I'm wondering ... have you actually tried something like a IR/UV cut filter ?

Hi Gareth,

UV-cut, yes. IR-cut no. UV-cut makes no difference at all (I tried with a Hoya HMC which is known to be particularly effective). I am pretty sure, the same applies to IR-cut (i.e., a filter that eliminates IR, not one that allows IR only to pass). The on-sensor filters of both kind are in all likelihood sufficiently effective.
