So I started the year with a Panasonic G3, a P20, O45, and O40-150. I was perfectly happy with the setup, then our baby came, and I became really frustrated with the slow AF of the P20. I swapped that out for the O25, then along came the E-PM2 deal, and down the rabbit hole I went... (From left to right: G5 w/ O45, Sigma 60, P14, P7-14, O40-150, P12-32, O25, VF-2, E-PL5 w/ O17, and Yongnuo 560 III and RF 603 II) I have to say, it's been a fun (but expensive!) journey. I'm not sure which ones I'll keep yet (they're all great lenses). If I had to choose one lens, it'd be the O25, but I see myself eventually settling into the versatility of the O17/O45 combo (love the 45). Now I just need to stay away from anymore purchases and get better at photography.
