For those of you pros who know the physics, is it possible for Sony (or anyone else) to design the next generation lens with a significantly better aperture - say 1.8 to 2.8 and keep the same form factor except for perhaps a larger lens diameter?

This is a very good question and I would be really interested in the answer. As far as I am concerned, the sony lens is a 4.9 one and it's pity. F1.8 at wide angle is an overkill; I don't need it there because I can use slower shutter speeds. At the long end of the zoom, I need the brightest lens I can get.

Panasonic just came out with a 24X superzoom with a constant f2.8 aperture! I thought it was technically impossible.

Could Sony make a constant f2.8 lens in the same form factor?
