Hi everyone,

I am trying to work out what the FOV in degrees would be for a Canon Mk2 and a Canon 17-40mm F4L USM lens combo, set at 17mm. Can someone please be able to help me?

I couldn't even find lenses on the Canon Aus. site :confused013 but the USA site has some specs (http://www.usa.canon.com/cusa/professional/products/professional_cameras/ef_lens_lineup/lens_uw_pro/ef_17_40mm_f_4l_usm#Specifications) and apparently at 17mm it has a 104 degree FOV.

A 17mm lens on a full frame sensor will give you a horizontal FOV of 91.6 degrees and a vertical FOV of 68.8 degrees. Which means you could do a 360 degree panorama in six shots with 25% overlap.
