37.5mm threads, 37mm filter, adapter needed?

Just a quick dumb question I can't find answered anywhere else: I have a videocamera with 37.5mm lens threads. A filter I want to buy online has 37mm threads (and that spec seem more common in general). There's a 37.5mm-to-37mm stepdown ring available elsewhere, but it costs twice as much as the filter. Is that 0.5mm really enough to need the stepping ring?
