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. On the other hand, Nikon S9700 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Below you can see the SX270 HS and S9700 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon SX270 HS and Nikon S9700 Cameras
Canon SX270 HS and Nikon S9700 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 compared to Nikon S9700, 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
Canon SX270 HS
or the
Nikon S9700 ,
including hyperfocal distance.
