Sensor Dimensions

[TessTickle]

Hello,

I am trying to calculate a ground sampling distance for my Mavic 3 using its Hasselblad camera. The specs that I do know are:

focal length: 24mm
image width: 5280px
image height: 3956px

I am only missing the dimensions of the sensor (i.e. sensor height and width). Would anyone know these?

Note: I haven't decided on my altitude yet

Thanks

18mm x 13.5mm according to [https://en.wikipedia.org/wiki/Micro_Four_Thirds_system]Wikipedia[/url]. Actually imaging area is 17.3mm x 13mm.

A four third sensor is 17.3mm wide and 13mm high.

Great! Thank you to both of you.

Remember that there is actual and effective sensor size. The whole sensor is not used, the edges are cropped to avoid fringing. Actual 20.9 million, effective 20million pixels

The specs that I do know are:
focal length: 24mm

The lens has an angle of view equivalent to that of a 24mm lens on a full-frame 35mm SLR camera.
It's actual focal length is 12.29mm ... not 24mm.
