Make the most of your existing collection of Pentax K-mount glass with this Vello Lens Adapter with Aperture Control that will allow you to mount these lenses to a FUJIFILM X-mount camera. Precise construction makes it easy to attach these adapted lenses to your camera and keeps it secure during use. Infinity focus is guaranteed, ensuring that you get proper functionality our of all your optics. This model features a built-in aperture control ring that will allow you to control the aperture of the lens for adjusting exposure and depth of field. Additionally, the adapter is made from a durable zinc alloy and features a matte black finish on the inside to reduce the potential for glare and reflections that can negatively impact image quality.
Although the lens will fit physically, autofocus, automatic diaphragm (AE metering), and other functions dependent on communication between camera body and lens will be disrupted by the lens adapter. You will need to focus manually, and to set exposures manually or meter in aperture priority (stop-down) mode. Focusing to infinity is retained.
