Originally posted by normhead Unfortunately I read on one forum that the 24 Mp APS-c sensors don't compare at all favourably to the 16 MP D7000, and they blamed that on the sensor at 16 MP already out-resolving the lenses. But I'd be happy to hear it if someone says different.
Interesting -
comparing the lowly <$500 Nikon D3200 24Mp,
with the class leading Nikon D7000 16Mp, and Pentax K-5 16Mp -
according to Imaging-Resource.com reviews (who are at least somewhat accredited) -
- with links to the respective reference pages:
Nikon D3200 24Mp

Resolution
Very high resolution, 2,400 to 2,500 lines of strong detail from JPEGs, slightly more from raw files.
Nikon D7000 16Mp
Nikon D7000 Review by IR
Resolution
Very high resolution, ~1,950 to 2,000 lines of strong detail from JPEGs, slightly higher from converted RAW files.

Resolution
Very high resolution, ~1,900 lines of strong detail from JPEGs, about 2,100 lines from converted RAW files.
EDIT to ADD -
from another source dpReview.com, again with links to the reference pages -
Nikon D3200 24Mp

the out-of-camera JPEGs, while clean of artifacts, are a little soft and and only resolve accurately up to approximately 3000 lp/ph which is less than we would expect from a camera with a 24MP sensor.
Converting your raw files and applying a customized unsharp mask (170%, 0.4 radius in our case) will get you a significant amount of additional detail. In our examples, here, there is some detail (albeit not 'true' almost up to the Nyquist limit of 4000lp/ph, which is the theoretical limit of the D3200's sensor resolution.
Sony SLT-A65 24Mp

neither the A65's JPEG nor raw output contains much meaningful detail beyond 3600 lp/ph.
Nikon D7000 16Mp
http://www.dpreview.com/reviews/nikond7000/13
JPEG files, the D7000 cannot accurately describe the 9 lines on our test chart much beyond 2600LPH (roughly), the RAW file still shows all nine lines distinctly at 2600LPH, and they only begin to merge at around 2800LPH.
Pentax K-5 16Mp
http://www.dpreview.com/reviews/pentaxk5/13
The K-5's default JPEG sharpening is conservative, but all nine lines of our test chart can be discerned up to around 2600LPH both horizontally and vertically. A lot more detail is apparent from our RAW samples, however, and vertical and horizontal detail is accurately described up to around 2800LPH,
