Panasonic LX100 has a
13.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor and features Venus Engine processor. On the other hand, Leica D-Lux 7 has a
17.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor .
Below you can see the LX100 and D-Lux 7 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic LX100 and Leica D-Lux 7 Cameras
Panasonic LX100 and Leica D-Lux 7 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 Panasonic LX100 has 32% larger pixel area compared to Leica D-Lux 7, 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
Panasonic LX100
or the
Leica D-Lux 7 ,
including hyperfocal distance.
