Applications & Features
The Super Crisp,Super Wide-angle
This fast, super wide-angle lens allows photographers to
experiment with different angles and perspectives. The Biogon T*
2,8/21 ZM offers outstanding performance and xtreme resolving
power even when shot wide open, with virtually no distortion,
excellent control of flare and ghosting and superb contrast
rendition across the entire frame. The slim lens design is easy
to grip and focus, and uses a standard 46 mm filter diameter
similar to many of the other ZM lenses and allows filters to be
interchanged between the lenses. The lens is rangefinder coupled
for easy focusing and the optional 21 mm viewfinder is available
for accurate image composition. Combined with a digital
rangefinder camera with a 1.3 crop factor, the lens has an
effective focal length of 27 mm. The Biogon T* 2,8/21 ZM is
suitable for many different wideangle applications including
reportage work, landscape and architectural photos. |
