I second that motion!

Just as a comparison of a translation from 4/3 to m4/3:

Specs for the 4/3 Zuiko 70-300mm f/4-5.6:

  • 14 elements in 10 groups
  • Front element rotates
  • Filter size: 58mm
  • 127mm x 80mm / 5.0 in. x 3.1 in.
  • 620g / 21.8 oz

Specs for the m4/3 M.Zuiko 70-300mm f/4.8-6.7 (~1/3 stop slower):

  • 18 elements in 13 groups
  • Rear element focusing
  • Filter size: 58mm
  • 116mm x 70mm / 4.57 in. x 2.76 in.
  • 430g / 15.2 oz

Significant size differential, 30% weight savings. If a m4/3 version of the 50-200mm f.2.8-3.5 achieved a similar weight reduction, we could expect something in the 700 gram/25 oz. range (4/3 is 995 g/35.1 oz).

That's less than half the weight of the CaNikon 70-200 f/2.8 1.5kg/3.3 lb behemoths. And with longer reach. [Yeah I know: DoF, equivalency, etc.].

It would be a very welcome lens!

FYI, "that rumor site" this morning has a possible Olympus 40-150mm f/2.8 zoom lens coming in January. If that's to be believed, it would be the 4/3 50-200mm f/2.8-3.5 replacement.
