From my unscientific experience given my particular copies I'd say the Contax G on a 16MP NEX 5N rivals the CY (28/2.8) on a Canon 5D2 on the per pixel sharpness. And in my mind that is quite an achievement given the difference in pixel density.
People are rightfully saluting the CY 28/2.8 for colors, cross-frame performance and so forth. And the sharpness for landscaping is good, but not exceptional like e.g. the ZE 21/2.8.
What the CY may have, compared to the Contax G, is more Zeissyness.
interesting, i do think the g45 has more of a classic zeiss look than the g28 does, but i like the g28 more because of that, and the g28 still has plenty of 3dness for me.
have you compared the c/y to g on the same camera or are you just comparing the c/y on the 5DII to g28 on the 5N?
