Gene, What's the depth of field with those?
I bought one of the $20 amazon "endoscopes". I was really disappointed in the depth of field. I have played with real endoscopes, and the amazing thing about them is their depth of field is from .5" to infinity. This one had a focal distance of about 4 inches and less than 6 inches of good depth of field. jerry On Thu, Oct 8, 2015 at 12:10 AM, Gene Heskett <ghesk...@wdtv.com> wrote: > Greetings all; > > I had one of those "colonoscopy" cameras you could buy on ebay for about > $22 USD on my toy mill, and had it pretty well calibrated but hadn't put > it to any real use as yet when I knocked it loose with an errant hold > down bolt on that furniture joint carving jig.
