Used with Olympus E-PL1 this objective equivalent of a 90 mm has an excellent quality-price ratio. Its sharpness is excellent, very good quality at full aperture blur, very soft. We can influence what fuzzy actually closing a little. We thus find finally on a Compact as the E-PL1 fine adjustments "old" ... With the common pitfalls such as high sensitivity to overexposure when one is fully open. The addition of a circular polarizing limit these effects in many circumstances, and at least on different skies.
Also big advantage: the very compact and lightweight. So I abandoned the very average 14-42 zoom and ride with me 17 pancake and 45, all for a very small footprint.
