[QUOTE="480sparky, post: 210548, member: 15805"] Simple math will tell you the FOV across the long end of the sensor. The lens projects 180° from corner to corner. Now, what is the dimension of the sensor corner to corner? From Nikons website, the D600's sensor is 35.9 mm x 24.0 mm. So the Pythagorean Theorem (a² + b² = c²) means 35.9² + 24² = c². 1288.81 + 576 = 1864.81. Square root of 1864.81 is 42.183. That means there's 4.267° per mm. Since the sensor is 35.9mm wide, 35.9 X 4.267 = 153°. [/QUOTE]
