Lens size

Suppose you take an F mount lens and repackage it in a Z mount barrel, so you have identical optics. The Z lens will necessarily be longer—since the glass elements need to be the same distance from the sensor—and of course it will be wider as well. But this argument doesn't hold if the optical formulation changes.

Also, I would think that increased use of engineered plastics instead of metal could make a lens lighter.
