By reducing the minimum focusing distance of Sony E lenses, the Viltrox Automatic Extension Tube Set also allows you to achieve greater maximum magnification for close-up shooting with any lens. This kit contains 10 mm and 16 mm tubes, which can be used independently or in combination for up to three different lengths to suit different types of subjects. 

Additionally, the built-in copper-coated contacts maintain full autofocus and auto-exposure functionality, and each ring features durable Sony E mounts on the front and back.
