Don't read this a s a recomendation, but the is a guy at DPReivew who does
wonders with the Bigma. His nick is The hotell. Try to find his pictures
and
see for yourself. But I do think he needs very good light to do his magic.
What I see from Sigma 100-300/4 and 1,4x suggests very good bokeh for a
zoom
TC combo.
