Originally posted by Oldhand I think that is a different lens - not the one with the constant f2.8 aperture.
But you are right about the grey imports being a similar price.

Sigma 18-50mm f2.8 EX DC Macro HSM
Need to back order - not in stock, but still good price for Aus warranty I believe.
But I am strongly leaning towards the 17-70 C just for the further reach. The handy thing with metadata is the ability to look at what focal lengths you have used. Outside of my super zoom shots, the majority is between 18-75, much lower numbers from 75-135ish.
Decision made, bargain hunting time
