For about a decade (~1950 to ~1962) Graflex manufactured a Graflok equipped version of the Crown Graphic and Speed Graphic in "3x4" format.
The negative format (actually 3-1/4in x 4-1/4in) has long been discontinued by major manufacturers, and while some niche labs may make small batches, I place this camera in the category of abandoned formats. And as such, it needs to be reborn.
So after some diligent eBay searching I found one, and spend several months deigning and prototyping and testing a smaller version of my "Graflok Universal 4x5" adapter to fit this rare version of the classic Graflex.
This particular combination of 3x4 with Graflok slide-bars is very rare, so take a close look at the pictures here and be sure of your camera model is an exact match before ordering this version of the adapter.
I'm pleased to announce that this new Graflex 3x4 Adapter is now available with it's own 82mm x 110mm focusing screen. The adapter is backwards compatible with all existing phone and digital camera cradles using the same twist-lock mount as the full range of ObscuraFlex adapters.
You can now harness the power of your smartphone or digital camera to capture digital stills and video with the look and feel of vintage large format photography using this exceptional and often forgotten classic.
This unedited sample image (except for rotation) was shot with a 101mm Graflex Kodak Ektar f4.5 lens on a 3x4 Speed Graphic equipped with ObscuraFlex 3x4 adapter using a Rocoh GR IV Monochrome at 400iso with an exposure time of 1/15th second.
Since this camera is so rare, I'm listing the adapter only as a stand-alone item, not as a kit. Phone or digital camera cradle, and screen must but ordered separately.
