Up to this the lens works properly and it is with 24, 20, 18 and 16mm where the incident angles of light reaching corners and borders do not create clean images. My first experience some years ago with Canon EOS 1Ds and 14mm f2.8 and 16-35mm f2.8 was very bad. Right now I've found that Nikkor 14-24mm f2.8 works perfectly on a Nikon FF DSLR even in the corners full open. Wiht a -promising- FF Leica M the 35 and up will work flawlessly and it will be the 24 and 21 -not to speak of trielmar Wide- which will find the big problems. The best approach in the digital reflex cameras is the Olympus where the extraordinary 7-14mm - an all the Zuiko E lenses- produce best images in corners and borders at full open but the price they have paid is a smaller sensor with bigger noise and lack of dynamic.
