This lens is beautiful. The depth of field is super nice, and even though it lacks stabilization, the G85's built in stabilization makes up for it. I bought this lens instead of getting the 25mm because with a MFT sensor, the 20mm ends up being like a 40mm.

The Panasonic Lumix G 20mm f/1.7 ASPH is an interesting little being. The center image quality is nothing short of phenomenal. The borders are slightly worse but still very good level and that's straight from f/1.7.

This lens is small, fast and sharp with a nice angle of view. It looks great on the camera and functions perfectly. A very good value. Love it.

Good quality fixed focus lens. It matches the Panasonic Lumix GX8 nicely for size and weight, giving a good street and general photography outfit with a focal length similar to human eye.

Easily Interchangeable; Lightweight; Strong Construction

The picture below illustrates the lens's angle of view (taken from our standard position):

Extremely small size and light weight - the perfect match for the E-P1 and GF1; Fast maximum aperture; Impressive image quality at all apertures; Good build quality; proper manual focus ring and non-rotating front element

Comparatively expensive (at least at launch; No lens hood

Launched at the same time as the Lumix DMC-GF1 camera Panasonic's Lumix G 20mm f/1.7 ASPH. lens will be offered with the camera body and makes an attractive kit option for serious photographers.

We compare the two Panasonic 20mm f/1.7 lenses to see if there are any additional benefits with the new version II lens.

Same excellent image quality as the original; Improved build with metal construction; Slightly improved resistance to flare; Improved design

Same focus system as old lens; Increased price

Given its 17.3x13mm sensor, the standard lens for a Micro Four Thirds camera (according to the rule of using the diagonal length of the sensor) ought to be about 22mm. That is close enough to 20mm for this lens to be viewed as a standard optic, especially given its fast f/1.7 aperture, which echoes...

f/1.7 fast aperture

slightly noisy AF

This Lumix G ‘pancake' lens is normally sold with the new Panasonic GF1 camera, but it's also available separately if you've bought the GF1 with the alternative 14-42mm kit lens, or if you already own a Panasonic G1 or GH1 camera. But who would want to swap a zoom for a fixed focal length lens?

Very useful lens to own. Indoor no flash photos are beautiful even inside a dark mission chapel.

Durable; Easily Interchangeable; Fast / accurate auto-focus; Lightweight; Nice Bokeh
