Well, now the Sigma seems to be very popular. In fact I thought about getting this lens myself and dumping the Tamron 28-75 and kit lens. If it were a constant 2.8 I would have no reservations but I am still contemplating whether or not I need the extra stop and a third. I did however just coax a co-worker into getting it with his new XT so maybe I can borrow his sometime and check it out.
So now it is time to post away. These threads seem to be pretty popular and people consistently post new pics all the time so don't be shy and post away.
