The 28 mm focal length on full frame gives us a quite significant angle of view, reaching 75 degrees. It is exactly the same angle we get at the shortest focal lengths with standard zoom lenses, which are usually a part of our reflex camera’s kit. In their case, the distortion often amounts to –4 or even –5%. With even greater satisfaction we notice the fact that on full frame the Canon 1.8/28 had barrel distortion which level we measured as – 1.85%. Such a value is noticeable but certainly not bothersome. The rival Sigma 1.8/28 had the result a bit lower –1.63%.
After limiting the lens’s angle of view to less than 52 degrees by attaching it to the APS-C sensor camera, the distortion decreased to the level of –1.19%.
