Weighing a mere 6.1 lbs., and folding to a compact 4.2" x 7.4"x 8.2", it combines modern alloy durability with classic design. It performs with the precision and convenience of a refined camera system for demanding pros as well as discriminating fine art photographers. Using handcraftsmanship, and over forty years of manufacturing expertise, Toyo achieves unparalleled precision and stability for rock-solid performance with the45AII. It offers a full range of camera movements, and unique features such as polymer coated parts for precision smoothness and Toyo's 360degree revolving back. The 45AII shares many versatile accessories with the complete line of Toyo modular studio monorail cameras. Movements for Creative Image Control The 45AII offers creative image control ideal for field use, as well as many studio applications. The front standard offers rise, swing, tilt and shift. The rear offers tilt and swing. With these controls, correction of distortion, adjustment of depth of field, and manipulation of selective focus are all possible. Drop Bed Design for Wide Angle Lenses Convenient operation is an essential advantage when considering a field camera. The 45AII offers a unique design combining compact frame, tapered bellows and drop bed displacement. This combination allows convenient use of wide angle lenses with a full range of movement. Unlike many other view cameras, the popular 90mm wide angle focal length can be used on a flat lens board offering easy access to all lens controls. The built-in tapered bellows eliminates the need for interchanging with wide angle bellows -an operation that can be a nuisance in the field, inviting dust and dirt inside the camera. The drop bed design allows unrestricted use of all wide angle lenses down to 45mm without unsightly obstruction of the camera's front edge in the picture. Telephoto and Macro Extension The 45AII's double extension bed and track are polymer coated for smooth, precise action and long-life regardless of shooting conditions. The micro-fine rack and pinion focusing front bed provides silky smooth focusing even with a heavy lens. The rear extension rides on two rails that can be easily adjusted to maintain a stable position for use with telephotos or long extensions. Control knobs are all-metal with rubber covering for easy grip with or without gloves. The camera's full 324mm extension allows use of 150mm lenses for1:1 life size macro work, or wide angle lenses for greater than 2x life size. A standard 210mm lens can be focused to 3.5 feet (1/2x life-size) for exceptional portraits and close-ups. Even a telephoto design 360mm,or standard design 300mm can be focused to ten feet for complete versatility in landscape work. When extreme close-ups are required, or an extreme telephoto lens is used, an optional 100mm extension back is available. It offers rock-solid extension and comfortable balance with heavier telephoto lenses. Revolving Back for Function and Convenience Changing from vertical to horizontal framing is a breeze with Toyo's 360郢evolving back. No worry of dropping a conventional reversible back, or allowing outside elements to enter the camera when changing position. An easy-lift bail arm allows fast and secure insertion of sheet film, Polaroid Rand many roll film holders without disturbance of camera settings or removal of the ground glass frame. For complete versatility, the 45AII back also features Graflok fittings for use with any type of film holder. Toyo's own acid-etched ground glass reveals translucent centimeter grid lines and discreet reference markings for 6x7cm and 6x9cm roll film formats. This permits critical composition and freedom from distracting black lines common on most 4x5screens. The grids and markings even simplify composition with creative 6x12cm panoramic format. The 45AII revolving back includes a precision factory-installed Toyo Super-Brite Fresnel lens in front of the ground glass. This enable seven illumination and consistent precision focusing. This combination also allows full corner-to-corner viewing, unlike most other camera screens that cut out the corners of the picture area.

The amount of extension needed would be: 1 x 150 + 150 = 300mm
