Fotodiox Pro PRONTO Autofocus Adapter Mark II for Leica M Lens to Sony E Cameras

Are you seeking a way to add autofocus to your Leica M lenses? Look no further than the Fotodiox Pro PRONTO Autofocus Adapter Mark II. This innovative device transforms manual lenses into autofocus powerhouses, compatible with Sony E-mount cameras. Simply attach your M-mount lens to the PRONTO adapter and experience the convenience of automatic focusing.The PRONTO adapter is designed for optimal performance with 50mm and wider lenses. For general use, it's suggested to set the lens to infinity focus, enabling autofocus within the entire focusing range. By half-pressing the shutter button, the PRONTO adapter activates the autofocus, making your lens function like any other AF lens. For telephoto optics, a coarse manual focus is required before fine-tuning with the adapter's autofocus feature.Enhance your close focus ability with the Fotodiox Pro PRONTO adapter. By attaching your lens and setting it to the closest focus distance, the PRONTO adapter doubles as a 5mm extension tube. This setup significantly shortens the minimum focus distance of your lens, with the effect being stronger the wider the lens.The PRONTO adapter features a Leica M-mount, but its versatility doesn't end there. With additional adapters, you can adapt nearly any lens to Leica M, attach it to the PRONTO adapter, and enable autofocus. However, not all adapters will be compatible due to size limitations imposed by the motor housing of the PRONTO adapter.The function button on the side of the Pronto 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. It's compatible with the Phase Detection autofocus (PDAF) system on the a7 II, a7R II, a9II, a6500, and a6600. This adapter supports both AF-S and AF-C focusing modes, face detection, and up to 5-axis stabilization on supported cameras. Please note that decreasing the focus area may result in a significant reduction in speed and potential focus hunting. The Pronto adapter is not recommended for cameras with only Contrast Detection Autofocus (CDAF) like Sony NEX, a6000, a7, a7R, a7S, a7Sii, etc., as it doesn't function properly with CDAF. Cameras in hybrid autofocus mode, such as Sony NEX, a6000 series, a7 & a9 series, may deliver unsatisfactory performance due to their reliance on CDAF. In conclusion, the Fotodiox Pro PRONTO Autofocus Adapter Mark II is a versatile tool that brings autofocus to your Leica M-mount lenses, enhancing your photography experience with Sony E-mount cameras.
