Im using a SenseFly SODA 3D camera, focal legnth 10.6mm, 1" sensor (5472 x 3648 pixel). Sensor dimensions are 13.2mm x 8.8mm. This calculates to a crop factlor of 2.7 therefore the 35mm equivalent should be 28mm. How come ContextCapture is reading this as 14.95mm equivalent (see attached screen shot)
