Mirrorless

Panasonic DC-G100D

The Panasonic DC-G100D is a mirrorless with a Four Thirds / Micro Four Thirds sensor measuring 17.3 × 13.0 mm. Its crop factor is 2.00×, so a 50 mm lens frames like 100 mm on full frame. Every number below is calculated for this exact sensor.

Focal length equivalents & field of view#

Multiply any focal length by 2.00 to get the full-frame field of view. Angles are for a rectilinear lens focused at infinity.

Equivalent aperture#

Exposure is identical at the same f-number on any format; equivalence only describes depth of field and total light.

Night-sky exposure limits#

Longest exposure before stars trail. The NPF rule accounts for pixel pitch and is stricter than the classic 500 rule — use it for pin-sharp stars on high-resolution sensors. (NPF needs a known resolution and is omitted here.)

Handheld shutter speed guide#

The reciprocal rule uses the equivalent focal length. High-resolution sensors may need one stop faster than this for pixel-sharp results.
