me to actually one of my best lensesI have older non OS version of this lens, in fact I have had it for quite a few years now, and have used it with a 30D, a 7D, and now a 5DMklll, Although my other lenses are Canon L series, I have never felt the need to upgrade from this Sigma, as the image quality is 'top notch'

Thanks for your input Dave. I don't doubt the IQ, it's AF speed and accuracy, as I will be mainly using it as a general portrait lens.
