I got mine 50 from Sigma NY for the third time. Still not focusing right! I will call them on monday again. I hope they'll replace it at some point. All I do with the lens is testing and sendig it to repair so far, and listen to their lies about lens being fine now. One would think that Japanese company would value something called honor. The truth is, they just making a buck at all cost, and if you got a lemon for your money it's your problem, not theirs!Nice shot! After getting my 50 back from Sigma, I think it just might be the sharpest (wide open) lens I own.
I like the build too. If only they would work! If only Sigma NY would fix them right instead of lying and cheating and wrenching out of their responsibility. I have two Sigma lenses and they both are crap. Both had been repaired by Sigma NY (my 50 f1.4 just return from the third round) and they both still an utter disappointment. That is why I hate Sigma!...and I love SIGMA lenses! Have only had a problem with one and that was my fault--it was fixed and returned to me within a week or so. I certainly prefer them over "plastic" lens bodies.
