D7000 doesn't do that well in resolution on DPR review. A55 scores better.

"The A55 makes good use of its 16 megapixel resolution and shows some detail up to approximately 3000 lp/ph which puts it in a similar ballpark as the 18MP Canon EOS 550D and a step ahead of the 12MP Nikon D90. The JPEG output is also fairly clean and free of artifacts and moiré."

"There is a clear difference in detail resolution between the D7000's JPEG and RAW output. Whereas in the JPEG files, the D7000 cannot accurately describe the 9 lines on our test chart beyond 2200LPH (roughly), the RAW file still shows all nine lines distinctly at 2400LPH, and they only begin to merge at around 2600LPH."
