The same view on every common format:

• Medium format (44 x 33): 20-45mm
• Full frame: 16-35mm
• APS-C: 11-23mm
• APS-C (Canon) (yours): 10-22mm

• 1/2.3-inch: 2.9-6.3mm

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.
