Canon EOS 7D	Pentax K-7
6.4MB JPEG (5184 x 3456)	9.3MB JPEG (4672 x 3104)

Both cameras deliver good sharpness on a pixel level. However, the 7D's higher sensor resolution squeezes a small amount of extra detail out of the scene. Again, at base ISO any differences in detail would only be visible at very large output sizes.
