Zenzanon PS50-100mm F/4.5
for Bronica SQ - 6 x 6 - Cameras
Tamron announced at PMA 2002 the release of the much-anticipated zoom lens for the Bronica SQ-Ai (6x6) camera system. The ZENZANON PS50-100mm F/4-5.6 is the first zoom lens developed for the Bronica 6 X 6 Format. Tamron went to work on developing this lens after the success of two zoom lenses for the Bronica ETR-Si (6 x 4.5 Format) that were introduced several years ago. The ZENZANON PS50-100mm covers a wide range (27.5mm - 55mm corresponding 35mm SLR focal length) frequently used in landscape and event photography.
While the Zenzanon PS50-100mm is designed for the 6 x 6 format, the engineers developed the lens with the size of the 6 x 4.5 zoom lens in mind. Usually, lens size will be directly proportional to film size; however, this Zenzanon PS 50-100mm lens was successfully downsized to almost the same size as the 45-90mm for the 6x4.5 format by devising a new mechanism. This new zoom lens will become a versatile standard lens for the Bronica 6x6 format system due to its compact size and focal range.
Image quality is improved from center to side; distortion is thoroughly compensated for throughout the zoom range and relative illumination is increased by the use of 2 large-size hybrid aspherical lenses.
The lens is ruggedly built to endure professional use. For convenience, the engineers adapted a shell mechanism for the front frame so that it does not rotate the way a 2 group zooming system usually rotates. This allows the use of our Flower-shaped hood (included) and PL Filter frequently used in landscape photography. The large flower shaped hood provides the maximum shading effect at all focal lengths.
The Zenzanon PS50-100mm F/4.5 is scheduled for April delivery.
