Everything you need to get your Graflok Slide-Lock compatible 3x4 Camera up and running as a vintage-style digital camera. Use this adapter to harness the power of your smartphone or digital camera to capture digital stills and video with the look and feel of 3x4 photography with most Graflok compatible 3x4 cameras from the 1950s onwards. This version of the ObscuraFlex adapter is designed to fit any 3x4 cameras equipped with standard Graflok style "slide-lock" mounting mechanism as patented by Graflex in 1949. I don't have the resources to confirm the compatibility of every camera that claims to be "Graflok Compatible" or even "Graflock" but many manufacturers introduced compatible Slide-Lock mechanisms. Check your camera carefully before ordering and compare with the photos and these measurements: Flange Dimensions: 102mm (4in) x 140mm (5.5in) Flange Thickness: ~6mm (0.24in) You probably know your camera better than I do, but if you still have questions after taking a close look at your camera, and comparing it to the photos here, feel free to email me via the contact page and I'll do my best to help.
