Thread: USB Borescope - now as good as a Hawkeye ?

That was likely the reason, yes The effectiveness hinges on the focal distance, and in the past 4-5cm seemed to be the predominant distance, so when used without the mirror then the part of the barrel that is in focus is just too far away for good resolution and at too acute an angle. Then with the right angle fitting, the mirror needs to be placed most of that 4cm distance away from the lens = less illumination and at that distance the mirror is a small % of the overall image size, so same result.

If anyone on here finds a model with an even shorter focal distance, like 8-10mm please would you let us all know ?

Exactly right. To say I was pleasantly surprised was an understatement; big O for Awesome.
