...more info please!....
Can you tell us a bit more about your cam? Seems a LOT of guys are experimenting, with varying degrees of success.
Is yours a dental cam, or one of those 'sewer snake' type, with a slim end, but straight facing view? I see there are angle adapter/mirrors available, so that's not a big deal.
Please let everyone know what you have, how close in it focuses, & where you got it ( if you don't mind)
thanks!
