Samyang 14mm f/2.8 IF ED UMC AS £330/$330
extra-large viewing angle, small price
Two ED (Extra-low Dispersion) and three high refractive elements in the optical path aim to boost image quality, while UMC (Ultra Multi Coating) helps to minimise ghosting and flare. Vignetting is minor, even at the widest aperture of f/2.8, but sharpness could be better and the extra-wide viewing angle comes with heavy barrel distortion. This aspherical (AS) Samyang lens has the outright widest viewing angle of any lens here, at 116 degrees. It’s even worth considering as a wide-angle prime on a DX format camera, where the effective 21mm focal length gives a still-generous viewing angle of 94 degrees.
As with the other manual focus lenses on test, the generous rotational travel of the focus ring enables precise adjustments. Samyang has missed a trick, however, by not adding depth-of-field markings to the lens barrel.
The built-in hood shrouds the front element, adding physical protection, but it precludes the easy attachment of any filters. Performance
