Over the course of this review, we've taken an in-depth look at the optical performance and handling of the Samyang 10mm F2.8 ED AS NCS CS ultra-wide prime lens. With its extreme field of view of 109.5°, this lens deserves extra recognition by the Pentax community, as it's the widest non-fisheye...

    Widest rectilinear prime available for Pentax, Exceptionally sharp across the frame, Fast F2.8 aperture, Unobtrusive barrel distortion, Good contrast, Minimal chromatic aberrations, Resistant to ghosting, Nice starburst effect at night, Compact and easy to carry, Automatic aperture control (full P,...

This manual focus wide angle lens for APS-C format cameras, offers a fast angle of view equivalent to a 15mm lens, with a relatively fast maximum aperture of f/2.8 for a budget launch price of around £429.

Such lenses as the Tokina 11–16 mm f/2.8 and the Sigma 10–20 mm f/3.5 raised the standards very high because both are very good instruments. Still we thought that the Samyang 2.8/10, being a fixed-focal lens with parameters not so far removed from those of the zooms, would be able to defeat the...

    sensational image quality in the frame centre,, sensibly corrected chromatic aberration,, good correction of spherical aberration,, not especially high coma,, moderate astigmatism,, interesting parameters.

  • -

    weak image quality on the edge of the frame,, too high distortion,, work against bright light should have been better,, distinct vignetting.

Overall, this lens is a good performer, for a decent price. The combination of good sharpness levels and a relatively fast f/2.8 maximum aperture should have London estate agents excited, as they will be able to make their dark dingy shoebox-sized bedsits look like bright, airy mansions, thanks to...

  • +

    Good value for money, Excellent sharpness in the centre from maximum aperture, Very good sharpness towards the edges stopped down to f/4 or beyond, Hyperfocal scale, Low CA levels, Good build

  • -

    Wavy distortion pattern may be difficult to correct in image editing software, No hard infinity stop

Very good value for money, especially for architecture and landscape photo, where manual focus is not a problem.

  • +

    Very wide angle, very sharp across the frame when stopped down to 5,6 and more (edges equal to tokina 11 - 16mm), proper size and weight do Nikon D7x00 cameras. Distortion is not a big problem.

    little bit softer wide open
