Originally posted by roentarre The 55mm lens perspective remains the same at this focal length and the imagery is closer to our normal vision.
The FOV of the DA*55 is 28.6°. It is not even remotely similar to how we see.
Our stereoscopic field of view is 100°; including peripheral vision it is 120°. Outside this we see with one eye or the other for a complete field of view up to 180°. The binocular field, within which both eyes observe an object simultaneously, has been defined as between 50 and 60°. That's a closer approximation to what looks "natural".
Many great photographers preferred the unmediated look of 28 or 35mm on full-frame. Check out the history of Leica for examples. These focal lengths produce a FOV of 76° and 53° respectively.
On digital 20-24mm seems the sweet spot. We need a DA* 24 f/2.
