The 35-70/3.5-4.5 was designed as a replacement for a normal lens... many of
these designs are smallest at ~50mm focal length, so that the lens will fit
into the 'never-ready' case the same as a fixed 50mm focal length lens. Then
when you uncover the lens, the 'at rest' setting is the familiar 'normal'
focal length from which you zoom wider or narrower. I have a Tokina 35-70
and a Tamron 35-80 (? -- I didn't go look) that also are shortest at ~50mm
focal length setting.
