Leica TL has a
16.0MP APS-C (23.6 x 15.7 mm ) sized CMOS sensor . On the other hand, Samsung Galaxy NX has a
20.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor and features DRIMe IV processor.
Below you can see the TL and Galaxy NX sensor size comparison.
Sensor Size and Resolution Comparison image of Leica TL and Samsung Galaxy NX Cameras
Leica TL and Samsung Galaxy NX 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
Leica TL
or the
Samsung Galaxy NX ,
including hyperfocal distance.
