I will add to this thread over time, and while I didn't intend to start a comparison of one system against another, I did a similar shot the other day with both my E-P1 and Nikon D90. I post this mainly as an example of how differently these cameras behave and as a matter of interest. I don't intend people to ditch one camera for the other. I see these as complementary photographic tools. See Post # 5 for the correct images. I have left these here as there has already been comment on the images. The E-P1 was fitted with a Voigtlander 25mm f/0.95 and this shot was taken at f/2. 23 V The Artist's Tools - Voigtlander 25mm f0.95 @ f2 by peterb666, on Flickr The Nikon D90 was fitted with a Nikkor 10-24mm f/3.5-4.5 zoom set to 24mm and taken at f/4.5 24 N - The Artist's Tools - Nikkor 10-24mm @ 24mm and f4.5 by peterb666, on Flickr The picture is of a spray can in the window of an abandoned tram carriage. I am a little surprised how differently these images are rendered. One thing that is obvious is the Nikon does have better dynamic range. Look at the detail in the ceiling of the carriage and brighter whites, yet the blacks are still quite strong (the black edging to the yellow star). I quite like the general detail of the Voigtlander lens. The are no problems there at all. The Voigtlander bokeh literally creams the Nikkor lens which has some excessive doughnuts around bright bits. IMHO, the main differences here are in the camera's sensors and the effect on the dynamic range. In isolation, both cameras do their job well but the Nikon D90 performs better. How do you see it?
