I am not sure if this is what you are inquiring.
This is output from RAW without processing and not using Silkypix from Pana.
This is jpeg straight from camera without processing.
There isn't any difference in the perspectives but I think the RAW looks better. I like this lens because of its size and weight and the output from it is not bad. More photos here:
Hi pkong1008,
Thanks. I am actually looking for something like this at the following link. Some of the m4/3 lens are having some form of distortion that are being auto corrected by the processing engine of the camera.
