Olympus SZ-11 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features TruePic III+ processor. On the other hand, Sony H400 has a
20.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor and features Bionz(R) processor.
Sony H400's sensor provides 6MP more than Olympus SZ-11'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 SZ-11 and H400 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus SZ-11 and Sony H400 Cameras
Olympus SZ-11 and Sony H400 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Olympus SZ-11 has 44% larger pixel area compared to Sony H400, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Olympus SZ-11
or the
Sony H400 ,
including hyperfocal distance.
