In this review, photographer Gary Perlmutter evaluates the Samyang 12mm f2.0 NCS CS lens using a Fujifilm X-T1 camera, testing it as a budget-friendly alternative to pricier native Fujifilm lenses for a commercial real estate assignment. Priced under £300, this ultra-wide manual lens requires specific menu adjustments because it lacks electronic communication with the camera body; users must enable the "shoot without lens" option and manually select a 12mm focal length in the "mount adaptor setting" to ensure the focal length logs properly in EXIF data. Perlmutter notes that while the selected aperture does not transmit and defaults to f1.0 in editing software, Adobe Lightroom users can apply the Zeiss 12mm Touit profile to effectively correct any lens flaws. Despite the manual operation, focusing is straightforward on Fujifilm bodies by leveraging built-in assists like focus peaking or focus zoom. The reviewer highlights several prominent pros, including the lens's exceptional value, a robust metal construction, small size, excellent contrast, smooth focus and aperture rings, and great sharpness—especially when stopped down, though it remains highly usable wide open at f2 for low-light...
