Panasonic 100-300 help please

I have just bought the Panasonic GH4 AND 100-300 lens having been using my FZ200 for several years. I have taken some test photos at full zoom (both 600mm equivalent) with both cameras to get a feel for the new one. I was surprised and a little disappointed that the gh4 photos looked noticeable softer than those with the FZ200 and this was very apparent when looking at the images at 100%.

I had read lots of reviews forums etc before buying the new camera and lens and was aware of the comments about the lens being soft .However I was not expecting it be this soft. I don't know whether the results are what I should expect from this lens or whether I have a bad example which needs returning so feedback or advice from other users would be much appreciated.

I attach two specimen photos. I chose aperture priority and set it at F5.6.
with ISO AUTO. The fz200 chose to shoot at 1/100th iso400 whilst the gh4 chose 1/640 iso2500. The difference isn't quite so obvious as on the originals  as I have resized them to fit here. They are straight out of the camera and I haven't done anything about any firmware updates.
Many thanks
