I have the Fisheye of Samyang (the same as Walimex only the name is different - same production) now really excited for half a year in use and am. I was skeptical at first, because it is manual, but I am fully satisfied. One must not forget that the others with automatic focus like cost three times times! Who it is worth the money to spend 700 euros or more, which is this left to itself, can I get with my Samyang 8mm least as good photos out: o) In this focal length manual adjustments are not a problem and there one with such a lens yes anyway does not make macro shots, it is also a relative novice like me very easy to use. The luminous intensity adjusts the sharpness is good and built it high quality. Thus, a clear conscience 5 stars!
