Editing Rangefinder camera (section)

=== Difficulty integrating zoom lenses ===
The rangefinder design is not readily adapted for use with [[zoom lenses]], which have a continuously variable field of view. The only true zoom lens for rangefinder cameras is the Contax G2 Carl Zeiss 35–70&nbsp;mm Vario-Sonnar T* Lens with built-in zoom viewfinder.<ref name="Contax G2 Vario Sonnar T">{{cite web | url = https://www.casualphotophile.com/2018/01/19/contax-g2-camera-review-the-anti-rangefinder-thats-in-a-class-of-its-own/ | publisher = Casual Photophile | title = Contax G2 Camera Review – The Anti-Rangefinder That's in a Class of Its Own |author=James Tocchio|date=January 19, 2018|website=www.casualphotophile.com|access-date=October 11, 2018}}</ref> A very few lenses, such as the Konica M-Hexanon Dual or Leica Tri-Elmar, let the user select among two or three focal lengths; the viewfinder must be designed to work with all focal lengths of any lens used. The rangefinder may become misaligned, leading to incorrect focusing.
