First, your equation makes no sense. Next, using the actual distance equation derived from the magnification equation:
D = f*H/h, and
f = D*h/H, where
D = 7000mm
H = 3500mm
h = 24mm
Therefore, f = 48mm, not 42mm.
HOWEVER, this distance equation is NOT applicable to nearby objects, ONLY for objects considered to be at infinity:

This equation was never used to calculate the UFO’s distance or size. It sounds to me as if you haven’t actually read Zahi’s WCUFO investigation. Have you?

Taro, Zahi posits that in WCUFO photo #800, the object is 3.5 meters at 7 meters away from the camera. Using the camera-object distance equation (D/d=f/h) which you lately have concerned yourself with, I found the size of object image on film as 24 mm. This gave me a focal length of 42 mm, which contradicts the 55 mm focal length value Meier asserts.Did I make any mistake?
Is that equation not applicable to cases when the camera is focused on nearby objects and not at infinity?
