Fotodiox PRONTO AF For Manual Focus Lenses

Fotodiox released their PRONTO AF adapter for X-Mount, which originally started as a Tech Art AF adapter, which I have tried and works very well. We should see the Fotodiox Pro PRONTO Autofocus Adapter for X-Mount at B&H Photo, Amazon, and Adorama soon.

Product Highlights:

  • Add autofocus to your Leica M-mount manual focus lenses; Ideal for 50mm and wider focal lengths
  • Improve close focus ability of all supported lenses; super light and compact
  • Further adapt to other lens mounts to increase your autofocus capability
  • Compatible with Fujifilm X-Mount Cameras; Support AF-S & AF-C mode
  • Limited 2-Year Manufacturer Warranty

Add autofocus to your Leica M lenses
A manual lens needs to be focused manually; Think again! The Fotodiox Pro PRONTO adapter brings autofocus to your Leica M-mount lenses. If you want to automatically focus your M-mount lenses on your Fuji X-mount camera just attach it to the PRONTO adapter. For general use, it is recommended that the lens be set to infinity focus allowing autofocus within the entire focusing range of the lens. Half-press the shutter button to activate AF and the PRONTO adapter will focus your lens just like any other AF lens. Performance is optimal with 50mm and wider lenses. Telephoto optics may require coarse manual focusing before use of the adapter for fine tuning via autofocus.

Improve close focus ability
Improve close focusing with the Fotodiox Pro PRONTO adapter by attaching your lens and setting to the closest focus distance possible. This setup will allow you to use the PRONTO adapter as a 4.5mm extension tube with autofocus capabilities that will significantly shorten the minimum focus distance of your lens. The wider the lens, the stronger the effect will be.

Add a second adapter for more lens options
The PRONTO adapter has a Leica M-mount, but the options don’t stop there. With the use of additional adapters you are able to adapt nearly any lens to Leica M, attach to the PRONTO adapter and enable them to be used with autofocus. Not all adapters will work due to size limitations imposed by the motor housing of the PRONTO adapter.

Auto Focus Speed:
The PRONTO adapter relies on the phase detection sensors of your camera and is not intended to support contrast detection auto focus. Due to this, focusing is only possible where phase detection autofocus sensors are located and may result in differences in real world performance from model to model.

Auto Focus Limitations:
Because the PRONTO adapter relies on phase-AF, not all of the AF features of your camera work; notably the Eye AF & Lock-on AF do not function properly.
