Samyang 12mm f/2.8 ED AS NCS Fisheye

This full-frame manual focus fisheye lens provides a 180-degree diagonal angle of view. It is known for its high optical performance, utilizing three extra-low dispersion elements and two aspherical elements to maintain sharpness even at the edges of the frame. The NCS (Nano Coating System) helps to reduce reflections and increase contrast, making it effective for creative landscapes and architectural photography where a distorted perspective is desired. Inspect the large, bulbous front element carefully, as it is prone to contact damage and cannot accept traditional screw-in filters. The integrated petal-type hood should be securely attached and free from cracks. SDS examines the mechanical aperture linkage and ensures the focus ring has the correct amount of resistance for precise adjustment, while checking the internal glass for any signs of blooming or scratches.
