Olympus M.ZUIKO DIGITAL ED 75-300mm F4.8-6.7 II lens review: Updated design and new lower priceBy Kevin Carter - Friday July 26 2013 Lens Review
Olympus M.ZUIKO DIGITAL ED 75-300mm F4.8-6.7 II vs previous version
Compared with the lens it replaces, the addition of the firm’s ZERO lens coating appears to have improved the performance in several key areas. Not only is the DxOMark Score now at 10 points, versus eight for the older version, for many photographers the increase in sharpness from 4P-Mpix to 6P-Mpix is more significant. Not only that, but the new lens is brighter and has lower levels of chromatic aberration.
Olympus M.ZUIKO DIGITAL ED 75-300mm F4.8-6.7 II vs Panasonic LUMIX G VARIO 100-300mm/F4.0-5.6/MEGA O.I.S.
Compared with Panasonic’s $599 stabilized Lumix G Vario 100-300mm f/4.0-5.6 the updated M.Zuiko is sharper over a wider range of focal lengths and apertures, and has comparable levels of vignetting and chromatic aberration. Distortion is a little heavier but still low and unlikely to be a concern.
The biggest drawback is lens speed; it’s over ½ stop slower, which can also adversely affect contrast detection AF systems, as well force the user to increase sensor sensitivity.
