Canon 350D has a
8.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor . On the other hand, Pentax Efina has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Pentax Efina's sensor provides 6MP more than Canon 350D'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 350D and Efina sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 350D and Pentax Efina Cameras
As seen above, Canon 350D has a 11.7x Larger sensor area than Pentax Efina. 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.
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
Canon 350D
or the
Pentax Efina ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C versus 1/2.3-inch),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
