Head-2-Head Micro 4/3 Kit Lens Review: Panasonic Lumix G Vario 14-45mm vs. Olympus M.Zuiko Digital ED 14-42mm
Falloff/VignettingBy Alex Burack
Corner falloff, or vignetting, has long been used as a creative or aesthetic tool to control focus and frame or border the subject within a shot. However, when unintended, the darkened, uneven illumination can be distracting and ultimately take away from the overall clarity of the photo. Falloff can be corrected easily in Photoshop, but the artificial brightening of the edge of the frame can increase noise and alter the quality and consistency of the file.
On balance, Olympus’s 14-42mm M.Zuiko lens maintains illumination far more consistently across the frame, throughout the bulk of the focal range. Panasonic’s 14-45mm G Vario lens does produce a more even edge-to-edge exposure in the mid-portions of the focal range, but the overall advantage here is significantly in favor of Olympus.
