Sony A35 has a
16.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz processor. On the other hand, Sony A33 has a
14.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz processor.
Below you can see the A35 and A33 sensor size comparison.
Sony A35 and Sony A33 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 Sony A33 has 14% larger pixel area (26.13µm2 vs 22.87µm2) compared to Sony A35, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
