About 3.5 inches long when compact, it's slightly larger than its predecessor -- big enough to cast a shadow at close-focusing distances and wide focal lengths when used with the E-30's pop-up flash. It's unusually well marked, with large, bright numerals in orange (feet) and white (meters and focal lengths). A blue band echoes the E-30's accent colors. The ribbed, ample manual-focus ring turns smoothly, with no stops at the extremes. The knurled zoom ring is large and adequately damped, if slightly stiff. AF is near-silent, and noticeably faster than the original in live view.
