Olympus E-620 with 14-42mm f3.5-5.6 brand_Sigma Energizer Ultimate Lithium batteries areJust to get it out of the way up front, the Olympus E 620 is a Four Thirds format DSLR, not a Micro Four Thirds mirrorless camera. It's compatible with Four Thirds SLR lenses, not Micro Four Thirds lenses, and it has a real optical viewfinder rather than an EVF. It's still a reasonably compact camera, though, and still packs a tilt swivel screen and an in body stabilizer. It's got a 12mp sensor, built in flash, and a pretty good live view system, too.
