Its an f3.5 lens, that can't focus reasonably close and costs $450.

Not at all, the lens is a f/2.8. The aperture is a mathematical formula: F divided by D

  • F: focal length
  • D: diameter of the entrance pupil

That's it. The f/stop has nothing to do with the camera. If it was a Canon or Nikon and you would mount it on an iPhone 4S it would still be a f/2.8. The field of view would be different.
