It's difficult to tell how it will behave on a full frame sensor - it might have terrible borders
Anyway, considering all that praise given to this lens, it is more than likely that I had a lemon: I hated the image quality of my Sigma 100-300 - sharpness *way* below my old Nikon 80-200 f2.8, absolutely horrible bokeh, frequent focussing errors, etc. The only thing I liked was the build quality - real metal tank :-)
