3.4MP SD9 vs. 20MP DC-G9 Resolution Test
4

Panasonic-Leica 12-35mm f/2.8 X Vario lens, Sigma 17-50mm f/2.8 EX DC lens

1) limit of resolution* as 9% MTF, some texts use 10%.

G9: 28.2 lp/mm, SD9: 62.7 lp/mm

2) normally accepted** good contrast level 50% MTF.

G9: 17.1 lp/mm, SD9 28.2 lp/mm.

* Limit of resolution defined as when objects can not be distinguished apart, a.k.a. Rayleigh's criterion.

** also known as MTF50 as found in lens testing.

Just the one test posted for what it's worth to anyone interested.

In this test, the 3.4MP SD9 beat the 20MP G9 handsomely.
