Panasonic · Leica L · 1.00× crop

The Panasonic DC-S1 uses the Leica L mount with a 1.00× crop factor (about 36.0 × 24.0 mm sensor), 24.2 megapixels, announced in 2019. 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 5.98 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.

Focus at the hyperfocal distance and everything from half that distance to infinity is acceptably sharp (circle of confusion 0.03 mm). Use the hyperfocal calculator for other settings.

How to check the Panasonic DC-S1 shutter count

Panasonic Lumix cameras show a shutter counter in a hidden service menu on many models; EXIF tools rarely expose it.

ExifTool tag: (service menu). Always test an original, unedited file straight from the card.
