Sony TX66 has a
18.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features BIONZ processor. On the other hand, Canon SX710 HS has a
20.0MP 1/2.3' (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features DIGIC 6 processor.
Below you can see the TX66 and SX710 HS sensor size comparison.
Sensor Size and Resolution Comparison image of Sony TX66 and Canon SX710 HS Cameras
Sony TX66 and Canon SX710 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.
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
Sony TX66
or the
Canon SX710 HS ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus 1/2.3' ),
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.
