One could use the Oly 14-150 or the Pany 14-140 II in a much much more compact package. I'm not convinced the brightness difference is a big deal for photojournalists. The Pany is supposed to be pretty good (for what it is) but unfortunately wasn't reviewed by PZ.
Think of the Canon 28-300mm L. A monster lens, slow, yet loved by a certain community. And way, way bigger than the Oly.

The Canon 28-300 f3.5-5.6 would be equivalent to a 14-150 f1.75-2.8 in MFT land. Hardly comparable to the 12-100 f4 aforementioned. Such a 14-150 lens would undoubtedly be huge too. Furthermore, I'm not convinced a FF 24-200 f8 would be much bigger (if at all) than the 12-100 f4.
Pro lenses aren't often heavy because of the optical components but because of the construction.
I'm sure you could put the 28-300L into a plastic housing with a total weight of less than half of the current lens.
The 12-100mm could certainly be shaved by at least 150g using consumer-grade housing.
So which will be the better option 12-100f4 or 12-60f2.8-4. Curious how the price/performance turns out for the pair.
