ie the £300 one and the £600 2.8 lenses.
do they have same IQ or is the OS version really worth the extra £300.
I see the similar canon lens takes very nice pix but its over £700.
i'm assuming the sigma version is competing directly with this lens but
does the cheaper £300 version do the same job only without OS&hsm?
