Samyang 14mm f/2.8 MKII Manual Focus Lens for Canon M mount

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˚ 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. Image Sensor size: Full frame 35mm. Focal length: 14mm. Maximum aperture: f/2.8.
