There isn't a helluva lot new about the E-420, Olympus' minor update to its
Though Olympus makes a big deal about the E-420's size, in truth it's only 0.01 to 0.02 inches smaller in any dimension than its predecessor, and in fact weighs a couple of ounces more. Still, it remains relatively compact compared with the rest of the field. Olympus has increased the size of the LCD from 2.5 inches to 2.7 and made the grip a bit larger as well.
Some of the changes and enhancements seem to compensate for the white-balance and exposure problems we encountered with the older model, such as the new Shadow Adjustment Technology and improved white-balance algorithms. Olympus also says continuous-shooting speed picks up from its predecessor's three frames per second to 3.5fps.
Along with the E-420, Olympus announced a low-profile 25mm f2.8 lens (equivalent to 50mm in the Four Thirds standard); a kit with that lens will run $699.99. The body alone will cost $499.99, while a kit with the f3.5-5.6 14-42mm lens (28-84mm equivalent) will be $599.99. All are slated to ship in May.
