Editing Rangefinder camera (section)

=== Field of view ===
Rangefinder viewfinders usually have a field of view slightly greater than the lens in use. This allows the photographer to be able to see what is going on outside of the frame, and therefore better anticipate the action, at the expense of a smaller image. In addition, with viewfinders with magnifications larger than 0.8x (e.g. some Leica cameras, the [[Epson]] [[Epson R-D1|RD-1/s]], [[Canon 7]], Nikon S, and in particular the [[Cosina Voigtländer|Voigtländer]] [[35mm Bessa|Bessa]] R3A and R3M with their 1:1 magnification), photographers can keep both eyes open and effectively see a floating viewfinder frame superimposed on their real world view. This kind of two-eyed viewing is also possible with an SLR, using a lens focal length that results in a net viewfinder magnification close to 1.0 (usually a focal length slightly longer than a [[normal lens]]); use of a much different focal length would result in a viewfinder with a different magnification than the open eye, making fusion of the images impossible. There is also the difference of the eye-level since the eye looking in the viewfinder actually sees the frame from slightly below the other eye. This means that the final image perceived by the viewer will not be totally even, but rather leaning on one side. This issue can be avoided by shooting in vertical (i.e. portrait) orientation, shooting style and framing allowing.
