experimenting with cheaper low light lens solutions for u/w video, i was thinking if someone has ever tried using a cctv lens or one of those slr magic knockoffs (manual focus)?

assuming the lens fits in your housing (which most should since they are tiny), would it be possible to leave the focus at infinity and still have good quality u/w landscape videos, especially at low light? and/or would it be possible to make a diy focus ring for the standard olympus housings?

here is a sample of those cctv cameras. most go for 20-40 usd on ebay:
