With a 25mm focal length and 47 degree angle of view, this lens sits right
between wide and telephoto designs, making it a great choice as an all-around
lens for your photography. A fast f1.8 circular aperture delivers beautifully
soft defocused backgrounds for impressive portraits or when subject emphasis is
the desired photographic effect. An inner focusing mechanism assures fast and
accurate auto-focusing, and because it is an MSC design, it offers nearly silent
focusing operation a great feature when shooting HD movies.
