Techart PRO Leica M Mount Lens to Sony E-Mount Camera Autofocus Adapter

Introduction

Transform your all-manual Leica M-mount lenses into fresh autofocus glass for your Sony mirrorless camera with the Leica M Mount Lens to Sony E-Mount Camera Autofocus Adapter from Techart PRO. Offering compatibility with the PDAF system on the a7 II and a7R II, this adapter has a mechanism to physically shift lens position up to 4.5mm on the Z axis, enabling autofocus even on manual focus lenses. This adapter will support both AF-S and AF-C focusing modes and if the lens is set to its close-focus position, this adapter’s extension can be used to get macro capabilities.

For general use, it is recommended that the lens is set to its infinity focus position, enabling autofocus within its entire focusing range. Performance is optimal with 50mm lenses and wider, whereas telephoto optics will require coarse focusing with the lens before using the adapter for fine tuning via autofocus. In addition to adding autofocus, users can connect to the adapter via Bluetooth 4.0 and a mobile app in order to program lens data, up to 10 sets of which can be stored, and update the firmware. This allows for full EXIF data to be recorded when an image is taken and also enables complete compatibility with Sony’s 5-axis in-body image stabilization. Additionally, it is designed to support lenses weighing up to 10.6 ounces.
