How much money do you want to spend?
I have the Tamron 17-50 f/2.8 which is fantastically sharp with great IQ. It's the lil bro to the Tamron 28-75 f/2.8.
I have that combined with a Canon 70-200 f/4 L which is a great zoom lens for the money ($500 used). It has a creamy smooth bokeh that the 55-250 IS lacks. Then again, it IS a few hundred dollars more, so that's expected.
