Many thanks MBS
It might depend on what you already have - do you have any lenses that overlap either (or both) of those lens ranges?
As a general point, the 17-50mm is a standard zoom, covering the focal lengths of a typical kit lens (but with better quality), from moderate wide-angle up to short (portrait) telephoto - 26-75mm full-frame equivalent; whereas the 10-20 is a more specialised ultra-wide lens - 15-30mm FF equiv. Therefore the 17-50mm could stay on the camera most of the time, but the 10-20mm is more likely to have occasional uses.
Cheers.
