Versalab Parallel Alignment Gauge

Hello Ron,If you are thinking of using the Versalab gauge to align a DSLR for copywork, It should work without complications. The type of camera doesn't matter to the alignment process. The laser beam is reflected from a mirror held against the front surface of the camera or enlarger lens.This product is well designed and solid. The only wrinkle was that I had to replace the batteries before I could use it. They were completely flat on arrival.Regards,Peter M.
