You can certainly talk about the sense or nonsense of autofocus for an extreme wide-angle lens. I think at this focal length but one misses not autofocus really. At maximum aperture 2.8 provides you the focusing ring on 1.2 to 1.5 m and then has a focusing range from 1m to infinity. From Aperture 5.6, it is sufficient distance to 0.7- 0.8m adjust and has a depth ranging from 0.45m to New York. Reason for buying the Walimex Pro 14mm was actually an offer for a used Canon 14mm (new about 2100) in advance could make a few test shots with. Somehow there was a certain edge blur the brought me to googling on the subject of wide-angle lenses, and so I came across the Samyang or Walimex Pro. Strangely, the Walimex at Colorfoto was seen not as positive, but always judged very positively in English and Reviews at least the Canon asked the same or even considered the better lens. So the Walimex Amazon order and by fast delivery with the Canon compared. Now my purely subjective impressions. Contrasting the Walimex lies on a slightly warmer side than the Canon. In center field, both lenses are knackscharf. At the edges in Aperture 2.8 is the Walimex significantly sharper and to aperture 5.6 superior to the Canon. Vignetting can be seen at f 2.8 significantly, but neglected from Aperture 5.6. Here scores the Canon lens. When chromatic aberration for the scores Walimex clearly. Verzeichnungtechnisch is again the Canon with a clean barrel distortion better the distortion remembers when Walimex to a Kaiser Wilhelm beard. With PT-Lens or other software can correct this but wonderful. If you have made friends with the manual focusing only once, so you work somehow relaxed or entschnellt and may be more the motive to devote. The Walimex allowed to stay and my friend has to another buyer for Canon Search. Sample photo with Canon EOS 6D from 0,5m distance - sec 1/400 - Aperture 4.0.
