Sigma 24-70f2.8

I'm having a wee look at this lens ,lens description is Sigma 24-70f2.8 DG ,with it being the non EX would this be worth going for or not.I had one of these before it was a fantastic performer ,only thing is ,it was the EX DG version .Oh it's very keenly priced .

I wasn't aware there was a non EX version of this lens, are you sure it isn't :

My apologies ,of course your right .... It EX but not DG ,Sorry Clarky ,how on earth are people supposed to give advice when the wrong information's put down infront of them
