14.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor .
Below you can see the A700 and A350 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A700 and Sony A350 Cameras
Sony A700 and Sony A350 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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 A700
or the
Sony A350 ,
including hyperfocal distance.
