Calculations to have equivalent-to-500mm F.O.V. in binoculars?
Feb 21, 2010

What calculations would be required to determine if a 500mm (or other) lens on a DX camera is equivalent to the view through my zoom binoculars at some zoom setting?

It would be nice to try and walk around with my binoculars for a while to get a feel for what I would see and be able to capture with the 500mm f/4 AF-S VR lens, or also the 300 f/2.8 VR lens.

I am used to zooms (70-200), and want something bigger (300 VR or 500 VR lens). I would like to get a better feel for what their fixed focal lengths will provide in terms of reach ... so it would be great if I could set my binocular zoom to achieve this.
