Mount Vintage Lenses to Fujifilm G-Mount Cameras

Mirrorless cameras aren't only revolutionary because of their compact size; they're even more versatile for mounting lenses than their full-sized counterparts! Whether you're shooting digitally or on film, Fotodiox offers the world's largest selection of lens adapters with strong support for mirrorless camera platforms with hundreds of options for mounting both modern and vintage lenses. Mix camera/lens platforms or reinvigorate vintage glass; our adapters deliver infinity focus, manual aperture control, and a sturdy build for lasting quality.


Versatile, Dependable, Adaptable

Why would anyone in their right mind want to use old lenses on their shiny new high-performance DSLR or mirrorless camera? The simple answer is that many older lenses can capture images that have that elusive quality known as character. And for photographers who want to create unique images that express their personal style, character can be even more important than resolution numbers, corner-to-corner sharpness, etc.

The problem with many modern lenses is that they are often lacking in character which comes from aberrations and not from the near perfect lenses that are quite common today. Additionally a fully mechanical lens is likely repairable longer and less expensively than modern focus-by-wire lenses. Plus, you can change camera systems or your mount can get retired and your lenses aren't bricked. At the extreme case, some mirrorless lenses require firmware updates for every new body, so even if the mount stays around lenses won't stay on that update list forever (for instance Nikon's new E lenses are incompatible with cameras just two generations old).


Precise & Solid Connection; No Play Fit

Fotodiox employs Professional Photographers in every aspect of development and design to create products that are built to last. The Pro line of adapters is crafted to withstand the rigors and demands of the professional photographer. Our adapters are manufactured with precise tolerances, providing a solid, gap free, no wiggle connection for stress free use. No adjustments needed! Fotodiox adapters are meant to be taken off and put back on your camera as much as needed while remaining as precise as the day you bought them.


All-Metal Construction; Secure & Solid Fit

Fotodiox Pro adapters feature all-metal, no plastic construction to create a secure connection between your glass and camera that will not degrade over time, keeping the lens-camera connection secure with every use. We use chrome plated brass mounts for enhanced durability and reliability. All Fotodiox products are backed by our 24-month Fotodiox Manufacturer Warranty.

  • • For clarification on M39 Vs. L39 lenses and which adapters are best for which lens. Please check our M39 / L39 / LTM / LSM - Whats What? article in the Fotodiox knowledgebase.
  • • Many lenses designed for DSLRs (particularly 85mm lenses and longer, most 50mm lenses and all tilt/shift lenses) produce image circles large enough to cover larger medium format sensors (though their performance will only have been optimized for their native formats).
  • • Wide angle 35mm lenses (lenses wider than 50mm) will vignette on Fujifilm G-Mount Cameras
  • • 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.
  •  'Focus-By-Wire' lenses (such as Canon's STM or Nikons AF-P) requires power to engage the manual focus rings on the lens, since manual lens mount adapters do not power the lens, those lenses will not be able to focus.
  • • Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode.
  • • If your lens does not have a manual aperture control ring, the lens aperture will revert to its default position, which depending on the lens is either stopped down to its largest f-stop or opened up to its smallest f-stop.
  • • 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.
