I was editing this and noticed

After I published the Friday Image No 20 I decided to review my Olympus EM5 shots. I had taken a few of the same location with the extremely sharp Olympus 45mm prime. You can see one particular example above.

What I noticed, that took me completely by surprise, is that I can see traces of noise in the EM5 image which isn’t present in the GM1 shot when viewed at 100% magnification. I have always been impressed by the EM5 images and just how clean the images are, but the GM1 appears to surpass this when both cameras are used at their base ISO.

Panasonic GM1 at 100%. ISO200 with similar processing in Nik to the EM5 sample. Notice also the different colour handling of the two systems. I need to profile both of these cameras.

If you are wondering why I find this so important, it’s because this noise becomes amplified in post processing, especially when enhancing images with structure and dynamic contrast tools. The less noise is present, the higher the quality of the finished image and the less noticeable any image artefacts are.
