Panasonic Lumix 20mm lens
Encyclopedia
The Panasonic Lumix 20mm 1.7 lens is a pancake
-style prime lens
for Micro Four Thirds system
cameras. In the Micro Four Thirds format, it is slightly wider than normal
. It was the prime-lens option available with the GF1.
The lens is "focus by wire"- the focusing ring sends commands, while the actual actuation is via a motor, even for manual focus. Focusing is internal- the front element does not rotate, allowing the consistent use of polarized filters. The 46mm thread lets a Micro Four Thirds user share filters between it, the Panasonic 14mm
, Panasonic Leica 25mm
, and Panasonic Leica 45mm
lenses.
The lens is very favorably reviewed
, including descriptions as a "must have"
or "must own" lens. Criticisms include the use of software correction of distortion, and that the focusing motor is slower and noisier than lenses intended for video ("MSC"- movie and stills compatible).
