I had the prior model of the Sigma 400/5.6 before the APO model. I compared
it to my 300/4.5 with 1.4 extender. The Sigma had more contrast and sharpness
wide open but this advantage almost disappeared 2 stops from wide open.
Unfortunately the 1.4X will not fit on the Sigma or I might have kept it. The
weighty Tamron 400/4 was the Sigma's replacement though.
