Just was out and about and decided to do a non clinical test shoot off between the EM1 and the Nokia 808.
comparing olympus em-1 against 808 - a set on Flickr
It is interesting to note that the Nokia 808 38Mp JPG output is indeed very pure and unprocessed like compared to the Olympus EM1 out of camera JPG. It is only when we bring out the EM1 RAW that the 16Mp sensor shows its true colors and after upsampling to 38Mp can match and beat the 38mp 808 tiny sensor.
I know the Oly has alot more to offer camera wise compared to the 808, but for daylight landscapes, IBIS, and high ISO performance does not make much difference.
