Nikon S9700 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Canon SX270 HS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Digic 6 processor.
Below you can see the S9700 and SX270 HS sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon S9700 and Canon SX270 HS Cameras
Nikon S9700 and Canon SX270 HS 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 Canon SX270 HS has 32% larger pixel area (2.34µm 2 vs 1.76µm 2 ) compared to Nikon S9700, it has larger pixel area to collect light hence potential to 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
Nikon S9700
or the
Canon SX270 HS ,
including hyperfocal distance.
