Should be illegal to call an F4 lens "Pro" unless it is a specialty lens.
F4 for such range lens is good for video. Lacking F2.8 can be actually big plus for many.
I am huge fan for F4 lenses for interviews and casual stuff. They stop people from making one more error.
OM Digital Solutions GmbH is pleased to announce the development of two new lenses that conform to the Micro Four Thirds System standard.
The M.Zuiko Digital lens roadmap has been updated to include the M.Zuiko Digital ED 20mm F1.4 PRO compact large-diameter single-focal-length lens, and the M.Zuiko Digital ED 40-150mm F4.0 PRO compact telephoto zoom lens. Both lenses are from the M.Zuiko PRO series, which are compact and lightweight lenses that offer excellent resolution and, make the most of the unrivaled portability and image quality that is the hallmark of the Micro Four Thirds System. OM Digital Solutions will continue to leverage the characteristics of the Micro Four Thirds System to enhance its lineup of lenses and broaden the scope for photographic expression.
It's true that not having F2.8 can be useful, but the lenses I have seen so far have not impressed vs 2.8 options. Maybe this one will be better. The $99 Olly in more or less the same range is actually very sharp, but no constant F stop.
The newly announced Olympus 20mm f/1.4 Pro and Olympus 40-150mm f/4 Pro, recently announced in a lens roadmap, are not yet on the stand but are available in a few weeks and ePHOTOzine will be reviewing the optics as soon as they are available.
