I bought the Sigma, the non DG version, back in 2004 for my 300D. It has since then survived a 400D and a 7D. Although the 7D still gets some some usage, the majority of the shots is done with the 6D I bought a couple of years ago. I'm very unhappy with the shots from the 6D/Sigma combination and for that reason I've found myself using the 135 F2 instead, even if the situation craves a longer lens.
The biggest problem with the Sigma on the 6D is uneven image quality across the frame using focal lengths from 150-300 and apertures from F4 to F8. I would say that roughly 40-50% (depending on the FL and aperture) central pixels are sufficiently sharp while the other areas are suffering from some kine of blur that looks like motion blur. I guess the lens has always suffered from this phenomenon, but with the crop cameras the "sharp" part covered much more of the frame. Can anyone comment on this behaviour? At 300mm, the lens needs to be stopped down to F/16 for completely alleviating the issue. Please zoom into the attached image and look at the sharpness of the "unmown part" of the grass. ...
"Swirly bokeh". Sweet. Some find that a feature rather than a fault. You just need more interesting subjects than grass.
