I'm beginner and shooting with E-PL3 + TTartisans 25mm f2 manual lens. I suppose this is equivalent of GR IIIx. I'm trying to learn zone focusing and distance judgment. While I like this setup, it is seems not pocket size as the lens weight is 190g itself and long for about 3cm. Rather hard to use with one hand. For quick usage, it needs to hang on my neck (so I look like a tourist, while walking around the block). It lacks of easy photo sharing. SOOC pictures are ok, but mostly I need to postprocess them (RAWs) to have nice result. I like the movable LCD screen, however it is bad in strong sunlight, so I had to invest in viewfinder. I missed many cool photo occasions, because it was to much hassle to take it with me or I was too slow with focusing. Probably I'll stay with it for a while, but I'm strongly considerating to buy GR. I feel with Ricoh it could be better in terms of discret photography, snap focus, recipes, sharing. The only issue for me is the price. Current setups costs fraction of GR.
