Shortening the minimum focusing distance of Sony E lenses, the Automatic Extension Tube Set from Viltrox also enables you to achieve a greater maximum magnification for close-up shooting with any lens. This kit contains 10 and 16mm tubes, which can be used independently or in combination for up to three different lengths to suit different subject types. Additionally, integrated copper-plated contacts maintain full autofocus and autoexposure functionality, and each ring features durable Sony E front and rear mounts.
