Lens Description

The Panasonic Lumix G 20mm F/1.7 ASPH is a normal prime designed for cameras with a Four-Thirds (2X) sensor. This ultra-bright prime has a 20mm focal-length. It provides the same field of view as a 40mm lens on a Full-Frame camera.

This prime can focus down to 20cm from the imaging plane which gives it a maximum magnification of 0.13X. The lens offers a Quick-Shift AF system which lets the user simply rotate the focus-ring to focus manually. A built-in focus motor is used to set the focus-distance. It allowed Panasonic to optimize the motor precisely for this lens in order to maximize performance.

This lens is only available for Micro Four-Thirds. Follow this link for all current compatible digital cameras: Micro Four-Thirds mount cameras.
