Wouldn't you know it... just as we're about to finish up on the molds for our 5x7 Film Holders... a discrepancy pops up... the ANSI specification for 5x7 film holder thickness is 0.562 inches, so that's what we started tooling for. In the meantime, we picked up samples of various 5x7 holders (no Toyo's though)... none of which have the same thickness, and none of which agrees with the ANSI spec. Would someone who has a Toyo 5x7 film holder please measure the thickness? Better yet, would someone be willing to donate a Toyo 5x7 film holder for an autopsy? We would glady return 2 of our new film holders as a thank you for the donation.
