Macy's -- didn't see it in person -- but captured this shot from the Empire State Building using the 400mm (full zoom) setting of the new lens.
The perception of detail is pretty good; I did some mild editing in Snapseed.
The original size (22 megapixels from my 5D mark II) shows over-sharpening again (due to my editing in Snapseed).
On the iPad's 1024x768 display, judging the sharpening is a little difficult with files so large.
Luckily, at web-friendly sizes, the effect isn't overdone and looks fine. You can almost read the subway sign below the "bag" (left) when fully zoomed-in.
