I think you are doing OK.  Much of any problems you can see are down to atmospheric conditions which of course are amplified by cropping.

Moving from G7 to G80 I was struck immediately by the improvement in IQ presumably from the removal of the AA filter.  Cropping ability is noticeably improved.  I had gone, G5 - G6 - G7 and G80 and this was by far the biggest improvement.

The 100-400 is in a different league to the 75-300 and 100-300, only beware that you may find it not as good at first as the extra length increases stability difficulty and those atmospheric conditions.

100-400 is much better focusing than 100-300 mk 1, I can't comment on mk2.

Overall the combination in improvements gives you a big step up.
