I thought this might be of interest, Nino Leitner and I wrote a blog post on the GH2 cs. GH13, and using Canon glas on the GH cameras.

It is basically a summary (including video samples) of our findings, and it contains also a small film where the GH13, GH2 and the Canon 5D MKII can be seen (nightfootage), skipping the lenses throughout all involved cameras. I have to admit, that the Canon glass on the GH2 really made a huge difference compared to the Lumix lenses in terms of the "look".
But have a look yourself.
Have fun, Gunther
