    • 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 Sony e-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 with 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 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. Click here to see a list of compatible adapters for the PRONTO adapter.

    Fn Button, PDAF & AF-S / AF-C

    The button on the side of the Pronto is a function button which allows the user to enter various focus modes as well as setting the focal length and maximum aperture of the lens used on the adapter for optimum compatibility. Compatible with the Phase Detection autofocus (PDAF) system on the a7 II, a7R II, a9II, a6500, and a6600. This adapter will support both AF-S and AF-C focusing modes, face detection and up to 5-axis stabilization on supported cameras. Decreasing the focus area comes with a significant reduction in speed and may produce some focus hunting. Using any cameras with only Contrast Detection Autofocus (CDAF) is not recommended (i.e. Sony NEX, a6000, a7, a7R, a7S, a7Sii, etc) as the Pronto does not work properly with CDAF. Cameras in hybrid autofocus mode (i.e. Sony NEX, a6000 series, a7 & a9 series, etc) may give unsatisfactory performance due to their reliance on CDAF as well.

  • • Please note that the PRONTO adapter has a weight limit of 600g (1.3lbs) for the attached lens. Although this is difficult to exceed with M-mount lenses, it is easy to surpass when using a second adapter on SLR and Medium Format lenses.
