Trying to decide between these two standard zooms. They are to be used on both an F100 and a D70. I know about the main differences but I am still unsure. The 35-70 is about Euro 600, the 24-85 is a little more than half that (new and imported). 35-70: - one stop faster - sharper (significantly so?) - less reach - better built - heavier - noisier and slower AF 24-85: - more distortion (even in 35-70 range?) - how much faster AF ?? Would be thankful for some comments and experiences. How do the two lenses compare with regard to BOKEH and overall PICTURE QUALITY?
