Jonhock, for what it is worth, I appreciate you taking the time to calculate and post this.
While in college, I tutored someone in Calculus without ever having taken Calculus, yet I cannot do math in my head.
Thanks for this!

Does it ? Or does it act like a 18 - 55 mm lens would except that APS sensor camera only records the middle bit of what a 35mm film would ?
