Conclusion: The Lumix G 20mm F1.7 ASPH is a lens that we've been looking forward to seeing for real ever since Panasonic first showed a mock-up back at Photokina 2008 . The good news is that it's been well worth the wait - the 20mm is an excellent lens, especially considering its tiny size. It does well in all aspects of our studio tests, and produces fine images in a wide range of situations while also focusing quickly, silently and decisively.
Pros: 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
Cons: Comparatively expensive (at least at launch), No lens hood
Excerpt: Originally posted 2010-08-16 on Optyczne.pl In my opinion the possibility of using small, mirrorless cameras with tiny „pancake” lenses is their biggest asset. It seems that the producers of this type of equipment at least partially share that opinion because every company which offers such cameras also has a “pancake” lens in its line-up.
Summary: A fast, ultra-compact prime lens for Micro Four Thirds System cameras.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. Compact enough to make the GF1 a pocketable option, it also provides a fast f/1.7 maximum aperture that lets photographers shoot with a shallow depth-of-field. . .
Pros: You want a fast lens for available light photography and require high performance across a wide aperture range., You require distortion-free images., You have a compatible camera body. Don't buy this lens if :, You really need a zoom lens., You shoot lots of close-ups.
Conclusion: Panasonic Lumix G 20mm F1.7 ASPH to ciekawy obiektyw , który z pewnością zainteresuje użytkowników szukających uniwersalnego i niewielkiego urządzenia. Oferuje bardzo dobrą jakość wykonania i obrazowania, pod wieloma względami przewyższającą zbliżony ogniskową i światłem model Panasonic Leica DG Summilux 25mm f1.4 ASPH. Praktycznie ustępuje mu jedynie tym, co zmierzyć można jedynie subiektywnie - plastyką obrazu.
Summary: The Panasonic 20 mm 1.7 is a nice lens without real drawbacks. The optical performances are very good. The Panasonic 20 mm 1.7, coupled with a Panasonic GH2, nestles in terms of resolution between the best lenses for Micro-43, APS-C and full-frame together. From the measurements, it appears that the resolution in the extreme corners always lags behind the resolution at the center. In practice, it is not noticeable.
Pros: Good optical performances for resolution, chromatic aberration and distortion, Bright, Nice Bokeh, Compact construction and low weight, Solidly built and nice finishing
Cons: Vignetting at full aperture, no mechanical resistance when manually focusing
