Sony A350 has a
14.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor . On the other hand, Fujifilm X100T has a
16.0MP APS-C (23.6 x 15.8 mm ) sized CMOS X-TRANS II sensor and features EXR Processor II processor.
Below you can see the A350 and X100T sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A350 and Fujifilm X100T Cameras
Sony A350 and Fujifilm X100T 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 A350 has 13% larger pixel area compared to Fujifilm X100T, 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
Sony A350
or the
Fujifilm X100T ,
including hyperfocal distance.
