The 55-250 gets my vote also. My Son Mirax has this lens and it's a big step up from the Sigma 70-300 on the image Quality front for the price. I agree the 17-70 is not really extending you range by much. Problem with wide range zooms is the degree of distortion ( barrel & pincushion ) which can be problematical for building shots.
