Here comes the leaked press textfor the 12-4mm f/4.0 lens that will be announced with the E-m1III on February 12:
..High-performance standard zoom lens
Effective placement of special lenses in the M.Zuiko Digital ED 12-45mm F4.0 PRO lens allow for the world’s most compact, lightweight design covering a focal length from wide angle 24mm to telephoto 90mm (35mm equivalent). A small and lightweight focusing lens enables high-speed, precise AF for any subject. The lens features a dust-, splash- and freezeproof construction with sealing in 9 places to keep out dust and rain, providing peace of mind when shooting on the go.
..Superb macro capabilities
Enjoy intense macro shooting with a maximum magnification of 0.25x (0.5x 35mm equivalent) across the entire zoom range. The closest focusing distance is 12 cm at the wide-angle end, and 23 cm at the telephoto end, delivering a wide range of macro shooting effects such as wide-angle macro shots that emphasize a sense of perspective by capturing vast backgrounds, and telephoto macro shots for more significant background defocusing effects. Diverse macro effects are possible, such as Focus Stacking , which generates a single image on the camera with a large depths of field in focus from the foreground to the background.
..Fixed aperture value across the entire zoom range
Effective placement of aspherical lenses and ZERO (Zuiko Extra-low Reflection Optical) coating – which provides clear depictive performance – drastically reduces aberrations, ghosts, and flares for sharp, high-definition image quality. Suppressing loss of light at the edges of images makes it possible to obtain bright, clear depictive performance up to the very edges. Because the aperture value is fixed across the entire focal length, it is easy to control the exposure when zooming and recording video.
