...the 35-70 is not just better (siginificantly) than the old 40-80, it is also lighter 475g vs. 660g. The 35-70 is better in the center fully open and stopped down and the distortion is also better (-2% against -6% at the end). I would highly recommend the 35-70, If you want to stay in this zoom range. Otherwise the 28-85, although big and heavy it has even better performance. Please look at the MTF data of all lenses in the download section and read in the second topic of the forum how to interprete these numbers.
