OM System TG-7 has a
12.0MP (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features TruePic VIII processor. On the other hand, Fujifilm S9800 has a
16.0MP 1/2.3 (6.17 x 4.55 mm ) sized CMOS sensor .
Below you can see the TG-7 and S9800 sensor size comparison.
Sensor Size and Resolution Comparison image of OM System TG-7 and Fujifilm S9800 Cameras
OM System TG-7 and Fujifilm S9800 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 OM System TG-7 has 32% larger pixel area compared to Fujifilm S9800, 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
OM System TG-7
or the
Fujifilm S9800 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
( 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.
