What is 50mm on the panasonic lumix g100d in full frame?

50mm on the Panasonic Lumix G100D (Micro Four Thirds) gives the view of 100mm on full frame.

The same view on every common format:

• Medium format (44 x 33): 127mm
• Full frame: 100mm
• APS-C: 67mm
• APS-C (Canon): 62mm
• Micro Four Thirds (yours): 50mm
• 1-inch: 37mm
• 1/1.3-inch: 28mm
• 1/1.7-inch: 22mm
• 1/2.3-inch: 18mm

Crop factors are by the sensor diagonal, rounded as they're usually quoted; a format with a different shape (4:3 against 3:2) frames a little differently across the width. More in the focal length converter.

Computed from the sensor sizes, not written by a model.
