Lightbulb Comparing the new 12-40 Pro with the 12-60 SWD on an E-M1

Today, despite overcast weather and, at the end, spits of rain, I shot some back/back comparisons of the new 12-40 and the old favourite 12-60 SWD using an E-M1, fitting the 12-60 via an MMF-3 adapter.

The ISO was 200, and for the JPEGs the noise filter was switched off. A link to the RAW file is provided as well. Each lens was used at 12, 25 and 40mm and each focal length was used at full aperture, f/4.0, f/5.6 and f/8.0.

The JPEGs were imported into Lightroom 5.0 for inspection and selection but no image changes were made. These images were not taken under laboratory conditions - and the 12mm shots may have had some spots of rain in the lens surface. But the camera and lenses were tripod mounted and levelled as best as I could. The lenses were only focused once for each focal length on each lens photographed. A 2 second delay was used to allow the camera to settle before each exposure was made.
