- Description:
- The Adon Telephotographic Lens, (Patent). This differs from all previous types, inasmuch as it may be fixed in front of the ordinary lens without removing it from the camera. It can be adjusted to work at the same "infinity focus," thus obviating the necessity for focussing, and it very slightly reduces the intensity of the positive lens. When used alone, i.e., without the ordinary lens, greater magnification is obtained, and with moderate magnification shutter exposures may be made. An improved cabinet attachment (Patent) for studio cameras permitting of exposures being made within a fraction of a second after focussing in the ordinary way. Stigmatic Lenses. Telephotographic Attachments. Various Cameras fitted with Dallmeyer Lenses. The Dallmeyer-Bergheim Lens.
