Olympus has had as big a hand as any in kicking off the compact-but-capable mirrorless camera movement; But in recent years, its OM-D line has been more exciting — the SLR-inspired E-M5 was one of the first mirrorless cameras that advanced photographers could take seriously, and last years E-M1 was targeted squarely at pros. With the latest entry in the series, the E-M10, Olympus is aiming to take that same formula to a wider audience. Other camera companies have turned to plastic at similar price points, so Olympus is to be commended here.
