Samyang 24mm F1.4 lens review: Best 24mm lens for Canon full-frame EOS users?By Kevin Carter - Wednesday March 12 2014 Lens Review
Although the Samyang is a phenomenal performer, its sharpness wide open doesn’t match that of rival high-speed designs. Given the modest pricing it will no doubt continue to be a popular model but it would be all the more attractive with the addition of automatic aperture control and perhaps AF-assist (though it’s often unreliable without experience). There’s another, often overlooked benefit from the inclusion of data transmission – EXIF data stored in Raw files could be used by third-party software suppliers to apply lens corrections. Future updates such as these would seem likely but for now the Canon mount version is overshadowed by the better performing rivals.
