What is the shooting angle of sirui 24 mm lens?

The diagonal viewing angle of sirui 24 mm lens on a full frame camera is approximately 84 degrees, and the specific value may vary slightly due to sensor size. ‌
detailed description:
Sensor impact
Full frame (35mm): diagonal viewing angle of approximately 84 degrees, horizontal viewing angle of approximately 74 degrees.
APS-C format: Due to the smaller sensor size, the actual equivalent focal length is longer (such as Canon APS-C equivalent of about 38mm), and the diagonal viewing angle is reduced to about 61 degrees.
Compared to other wide-angle lenses
24mm is between ultra wide angle (such as 16mm) and standard wide angle (such as 35mm), with a viewing angle about 9 ° wider than 28mm, suitable for scenes that balance environment and characters.
For example, when shooting indoor portraits, 24mm can incorporate more background, but attention should be paid to edge distortion control.
