So while Olympus deliberately down-grade their m43 glass' image quality to avoid competing with their dSLR line up, they're shooting themselves in the foot...
I don't buy this. Everything I've read about Olympus' plans seems to indicate that they can't wait to ditch SLRs for mirrorless cameras. Why would they want to sabotage micro four thirds?
It's no secret that Olympus are working towards a pro grade :43: body, which will probably be substantially bigger than the Pen range, or at least accept a large modular grip. The aim is allow such a body to fully utilize all that lovely SHG glass in terms of balance and AF capability. If they pull this off they will have no need to produce anything but budget or SG lenses specifically for :43: That may well be the end of the traditional Four Thirds line of cameras but it's those lenses that Olympus regard as the jewel in their crown. SHG zooms are peerless and simply a class above the best of any other manufacturer, it's just a pity I can't afford them.
Back in the real world I'm happy to use either Oly or Panny :43: lenses, with a current preference for the Panny 14-45mm and 20mm.
