Both Samsung TL350 and Samsung HZ10W have 1/2.3-inch sized 10.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the TL350 and HZ10W sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung TL350 and Samsung HZ10W Cameras
Samsung TL350 and Samsung HZ10W 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 Samsung HZ10W has 12% larger pixel area (3.13µm 2 vs 2.78µm 2 ) compared to Samsung TL350, it has larger pixel area to collect light hence potential to 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
Samsung TL350
or the
Samsung HZ10W ,
including hyperfocal distance.
