I tried going over fully to M4/3 about 6 month ago. But unfortunately it hasnt worked out with what I have spent on gear, and I forced to liquidate all my M4/3 gear to my dismay. All the gear listed here is less than 8 months old.. All the gear is in mint shape, like New In box. You could not tell from new. Especially since I have all the packing, boxes, manuals, bags, hoods etc for all this gear. I haven't done a lot on the forum here as I was fairly new, but you can check out my feeback on ebay under the user name of ghostinz. for sale GH2 with 14-42, and extra battery, $800 PL 25mm 1.4 ASPH, $500 PL 45mm 2.8 macro ASPH, $575 Lumix G Vario 45-175mm, $325 Lumix G 100-300 Mega OIS, $400 picture upon request.
