Due to its technical characteristics, I expected a practical objective for social activities: light, small, bright, with a wide angle (28mm equivalent) that lends itself well to the picture with friends and family (diners, group, etc. .) is an optical one easy wins. On a Lumix GF1 (and probably a GF2), it can be even more discreet than 20mm. The picture quality is good, but not spectacular 'which is consistent with the idea of pancake goals. Very practical: the diameter is 46mm, like other fixed targets of the range, allowing exchange between all these optical filters.
