Showing 1-3 of 3

Conclusion: I have wanted a wider angle rectilinear lens since I got to play with a 15mm Sigma fisheye. When I received a 12-24 and taken couple shots, I was very disappointed by a band of softness on the left side of the frame. I contacted amazon, and they rushed me a new copy of the lens. The second copy did not have the soft side, but whenever focus was not at the infinity, background got soft - even dof scales predicted background being IN focus.
Pros: Lens is wide, colors are vivid, fairly sharp across the frame when focused at infinity
Cons: First sample was soft on the left edge of the frame, second sample is better, but dof becomes very fuzzy.
Summary: Lens flare is a very real issue. Light almost has to bebehind you to avoid it. There is no place for a filter (Therear gel filter guide is a joke.) so you can't use apolarizer to help with reflections on water. On the plusside it does render beautiful deep blue skies when you getthe right lighting. Problems Encountered: Mechanically, none. Flare, lots.
Summary: Sigma 12-24mm/4,5-5,6 EX DG asherical HSM Objektiv für Canon das objektiv ist zwar nicht schlecht, die ergebnisse bei vollformat sind aber nicht gut. das finish ist sehr empfindlich und wohl im dauereinsatz nicht beständig. brennweitenbedingt extreme verzeichnungen.
