Two aspherical lenses are perfectly configured to deliver enhanced performance
in a compact system. With this thin, pancake lens mounted, the LUMIX G Micro

LUMIX G 20mm / F1.7 ASPH.
The smaller the F-number, the shallower the depth of
field (the range in which things are in focus); the larger
the F-number, the greater the depth of field. This
lens, with its bright, fully open F1.7 aperture, lets you
capture the desired parts of an image in sharp focus,
while giving other parts a soft focus. This makes the
subject really stand out, adding a rich expressiveness to
the photo.
As I casually snap shots of an unusual gate at a street corner,
I use the F1.7's delicate soft focus to emphasize the texture of the rusty metal,
and transform an everyday scene into a work of art.
This lens has the power to give form to all of my artistic visions.
