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.
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 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.
Please note that the PRONTO adapter has a weight limit of 680g 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.
Camera Compatibility – Cameras with Phase Detection AF such as:
* Sony Alpha a6300, a6500
* Sony Alpha a7 II, a7R II, a9
* The PRONTO adapter supports AF-S and AF-C focusing. Decreasing the focus area comes with a significant reduction in speed and may produce some focus hunting. Face detection is also supported.
* We do NOT recommend using with Contrast Detection AF only cameras (i.e. Sony NEX, a6000, Sony a7, Sony a7R, Sony a7S, Sony a7Sii, etc)
The motor will make some noise; this is normal. This noise is minimal and should not be a hindrance in most situations.
Make sure this fits by entering your model number.
