Making do with zoom lens.


Post by Jennifer Christine » Tue Aug 20, 2019 10:55 am

I wanted to use a smaller guidescope, but couldn't justify buying a whole new one.
I seldom use my 70 to 300 kit lens so devised a back cover by cutting a hole and glueing a nose piece on and screwing a webcam on the back. Some small elastic band stopped the focus ring and zoom ring slipping.

Woorked great.
