Ever think about using a fantastic Large Format 4x5 camera with a Canon RF-Mount camera? Here is your solution! With this adapter you can mount your film or digital back onto popular large format 4x5 view cameras (works on all 4x5 cameras with the standard with graflok back, such as: Cambo, Linhof, Calumet, Horseman, Omega, Toyo, Kodak). This adapter board mounts the backs in a vertical position and slides from side to side allowing more of the scene to be scanned and captured. 


* Canon EF version shown in video; the controls and how to use the adapter apply to all 4x5 Stretch Adapters.

The entire digital image can be compiled using your computer. The sliding adapter allows you to 'scan' the 4x5 back so the multiple images can be stitched together using image editing software into a giant mega-file with amazing detail and clarity! The sliding board has incremental markings to help with positioning and a tension screw lock to keep the sliding board in place during shooting. This Fotodiox Pro-Series mount adapter is machined with pristine precision for the best possible fit. As with all Pro-series adapters, these have been specially crafted to endure professional lenses and repeated use. With unique styling, the lens mount adapter maintains/enhances the professional appearance.

  • • This adapter is designed primarily for 4x5 studio cameras that are much bigger units with plenty of space for all the tilt/shifts/swings. The smaller field cameras that fold down to a compact size (such as the Graflex Speed Graphics) don't have the space needed for the plate to mount and move, they usually have a recessed back and other things that interfere with the adapter plate mounting correctly.
  • • This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted.
  • • Some cameras need to be set a certain way to work with our adapters or you may get a message such as 'Error Lens Not Attached - Check lens'. Please check the support articles on the Fotodiox Knowledge Base for possible solutions on a variety of camera brands.
  • • Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode.
  • • To determine what the new 'Crop Factor' or 'Equivalent Focal Length' of the lens when used on your camera will be, please check the Fotodiox Knowledge Base article.
  • All pictures are for illustration purposes only. Actual product may vary slightly due to ongoing improvements in design.

Emily ★★★★★

Finally got this mounted on my Sinar and the precision machining is spot-on—locks solidly with no wobble during movements. Being able to compose multiple linear exposures for a stitched panorama is a game changer for architectural work.

Violet ★★★★★

This adapter lets me use shift and stitch movements with my mirrorless camera on my 4x5, which is exactly what I needed for architectural photography. The build feels solid and locks onto the Graflok back without any wobble.

Alexander ★★★★★

My Canon mirrorless finally feels at home on my 4x5 setup—the shift/stitch adapter makes tilting movements precise and repeatable. The Graflok rear standard locks on securely, and being able to do linear arrays for stitching has been a game-changer for my architectural work.
