Leica CL (Typ 7323)

Leica · Leica L · 1.53× crop

The Leica CL (Typ 7323) uses the Leica L mount with a 1.53× crop factor (about 23.5 × 15.7 mm sensor), 24.2 megapixels, announced in 2017. Below: equivalent focal lengths, maximum shutter speeds for sharp stars, a hyperfocal distance chart, compatible lenses and how to check the shutter count.

NPF = (35 × f-number + 30 × pixel pitch) ÷ focal length, with a pixel pitch of 3.9 µm (from 24.2 MP). The strict version (Michaud's detailed NPF for the galactic core) gives pin-point stars at 100% view; the 500 rule is a loose rule of thumb that shows trailing on modern sensors.
