Panasonic · Micro 4/3 System · 2.00× crop

The Panasonic DMC-GF8 uses the Micro 4/3 System mount with a 2.00× crop factor (about 17.3 × 13.0 mm sensor). 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 3.3 µm (typical for this format — exact resolution not in our database). 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.

How to check the Panasonic DMC-GF8 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.
