Re: I would like a 14-45mm II

The 12-32mm and 14-42mm are too slow. On the other hand the 12-35mm and 12-40mm are too heavy and not quite long enough. I would like a 14-45mm II with f/2.8-4.0. Current techniology and glass should make this possible at the same weight and with better edge-to-edge sharpness.

What you are asking for is approximately twice the light. That means twice the glass surface. So now the elements weigh double or more and, unless you are planning to use half as many, the whole shebang will end up being twice as heavy and larger in diameter.

Current technology already did its magic on the 12-32 and 14-42. There are physical limits; that's why they call it physics. Current glass is the same glass they've used since whenever. Affordable aspherical shaping and fancy coatings are new but optics and the specific gravity of glass is not going anywhere soon.

Prepare yourself to be disappointed with 'current technology'.
