Bokeh of Sigma 50-150 vs Tokina 50-135?
Has anyone done (or know of where to find online) a head-to-head comparison of the bokeh between the Sigma 50-150 f/2.8 and the Tokina 50-135 f/2.8? I'm particularly interested in the smoothness of the rendering of out-of-focus areas.
It would be especially good to see image samples to illustrate the rendering; from the searches I've done (on this site, and more generally googling around), people comment on them verbally ("nice bokeh") but don't provide samples. Photozone.de reviewed both lenses but unfortunately in these two cases, doesn't have results of the bokeh test provided for some other lenses there.
