I've made a focus chart to test parfocal lenses.
I’m making a focus chart to check if my lenses are parfocal.
It uses my computer screen and a target taped at 45 degrees. You can view it here: #13 Lenses The system works, but I'd like to improve it... so I'm posting on a few forums. If anyone with graphic skills wants to help... please write. Bill Kerrigan bill@kerrigan.ca http://www.kerrigan.ca |
