Helping to achieve a shorter minimum focusing distance with Fujifilm X-mount lenses, these MK-F-AF3 Extension Tubes from Meike also afford a greater maximum magnification for close-up shooting with any lens. This kit includes 10mm and 16mm tubes, which can be used independently or in combination for up to three different lengths to suit different subject types and desired working distances. As automatic tubes, integrated copper contacts maintain full autofocus and auto-exposure functionality for seamless use. Additionally, the tubes incorporate aluminum alloy bayonet mounts for a rigid and durable design.
