Resolution

At its lowest setting of ISO 100 and in the 4:3 aspect ratio, the LX100 II resolves close to 3,500 lines per picture height, which is essentially as much as it could theoretically achieve. Some aliasing is visible at higher frequencies owing to the lack of an optical low-pass filter. Resolution reduces gradually as the sensitivity is raised, with around 3200l/ph measured at ISO 800. However images are still reasonably clean at ISO 6400, which offers 2700l/ph. At the top setting of ISO 25,600 resolution falls to around 2400l/ph.
