Samyang MF14mm F2.8 Mk2 Fuji X-Mount Lens (7114) The Samyang MF 14mm F2.8 Mk2 is an ultra-wide-angle manual-focus lens with superb sharpness from corner to corner even at its maximum wide-open aperture. The 115.7 degree wide angle of view is ideal for shooting landscapes interiors astro-photography etc. and the attached lens hood effectively blocks unwanted light. The MF 14mm F2.8 Mk2 includes two completely new features: Focus Lock De-click. You can lock the focus ring at a specific point greatly improving precision and repeatability especially useful in astrophotography and time-lapse shots. The de-clicked aperture option allows infinitely fine adjustment between F-stops. By rotating the silver ring from Click to Free you can adjust the aperture smoothly and precisely to ensure exactly the right amount of light is captured. The 9-rounded aperture blades help to achieve excellent smooth and creamy bokeh in out of focus backgrounds. The 9 aperture blades also provide clearly defined sunstars when the aperture is stopped-down. Weather-sealing is located around the lens mount area to prevent infiltration of moisture and/or rain drops. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions.
