I have an OMD and have Oly lenses. Looking at expanding my lens portfolio and wondering about staying with Oly lenses or moving into Pan territory if the lenses give similar results. The main reason for this is trying to guess which would be the next model of camera body that would improve on the OMD. If I buy Oly lenses and the next body turns out to be a Panasonic then I lose image stabilization although all lenses will work on the new body. If I buy Pana I am ok with both brand of camera bodies. If the next camera body is Oly then I am ok but maybe missing out on good lenses like the 12-35. Coming from a Canon FF it was an easy decision, one had to stick with canon or with the eos mounts. I am a hoarder and rarely manage to sell stuff. Am I trying to futureproof my system too much??
