I have used it so far I can 8mm on a Canon 450D and a Canon 7d and after one year of experience with the Walimex report the following:
The lens makes images, the real eye-catcher are just something special. Places that are otherwise one could never catch this width scanned as follows: It is not the perfect sharpness as with an L lens, but quite usable, the colors of the images act as though a polarizing filter mounted - you always have rich colors to the pictures (especially blue sky and white clouds despite good ausgelichtetem ground, not burnt), which I really benefit, because I like so should capture landscape.
Impetus for this review was as follows: On holiday in high northern latitudes, an evening resulted in moderate auroras - in other words: This shimmered only greenish, but were not particularly bright. In order to get as much of the sky at the pictures, I mounted the Walimex and renounced my L lens with 10mm - I have not looked back! In combination with the 7d I received beautiful auroral images because the Walimex 3.5 apparently is light strong enough to capture those moderate auroras themselves. And even pictures that I made under a roaring waterfall survived it - I was soaking wet, the lens was protected in part by raincover repeatedly at the front of wet, so I had to dry the lens at every 2nd recording, but it has taken no damage it !!!
I am thrilled and can inspire people by Fisheyebilder and I had to spend no 1000 euros for it! :-)
