I have this lens and yes, it is normal if you shoot raw. Actually, what I discovered is that the lens is a little bit wider than 18 mm at the short end, and when shooting jpg, the image is slightly cropped, with still some residual distortion that I seldom correct, except for architectural pictures.. I totally agree with Pieter, the way lenses are designed has changed with the advent of digital cameras. In the old days of film, distortion, chromatic aberration and vignetting could not be corrected, especially when shooting slide film. This was not an issue with prime lenses, but was a major obstacle to zoom lenses development, up to the point tha magazines of the time warned against zoom lenses with more than 2-3X range. Today lenses are designed as Pieter said, compromises are managed by software and this is even more evident in smartphones and compact cameras, which intentionally have no raw option.
