Before you get into BIG trouble with BIG lenses, check out this DIY solution for mounting a barrel lens onto a lens board. Today I'm mounting my latest old-school purchase, a Graf Variable lens onto a Sinar lens board. I'm not using custom tools, but working with materials you can find at your local hardware store! After the lens is mounted, I'm also taking it out into the field to test it out with some paper negatives and RA-4 direct positives.
