Canon 1D MII N has a
8.0MP APS-H (28.7 x 19.1 mm ) sized CMOS sensor . On the other hand, Canon 7D has a
18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Dual Digic 4 processor.
Canon 7D's sensor provides 10MP more than Canon 1D MII N's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the 1D MII N and 7D sensor size comparison.
As seen above, Canon 1D MII N has a 1.6x Larger sensor area than Canon 7D. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
