Our Imatest tests showed the review lens was capable of exceeding expectations for the sensors of both the cameras we used for our tests: the Panasonic DMC-GH4 and the Olympus OM-D E-M1. Slightly higher resolutions were achieved with the E-M1 so we have based our test reports on images from that camera.
There was no evidence of coloured fringing in any test shots. Vignetting (corner darkening) was very well controlled and barely visible at the widest aperture setting. Rectilinear distortion was also effectively negligible.
Panasonic’s Lumix G Macro 30mm f/2.8 ASPH. MEGA O.I.S. lens is a welcome addition to the specialised close-up lenses available for M4/3 cameras. Offering the shortest focal length of the trio, it is likely to be the most affordably priced if US prices are any guide.
