The close-focusability of this lens is the best of all standard zooms, but no match for a real macro like the Sigma 70mm macro or the Tamron 90mm. If it is sufficient to fill the frame with something with a dimension of approx 6 cm, the 17-70 is Ok.

This lens at times surprises me both positively and negatively. It can be very sharp in the lower to mid focal ranges, but the performance at 50-70mm and wide open aperture is a little disappointing. Stopping down helps, and on occations where the choise is between lens softness and motion blur, the slight softness may be acceptable.

If I was buying a standard zoom today I would perhaps bill out some more to get the Sigma 17-50 f/2.8
