The history - SLV and T30

The production of the Silvestri cameras started in Florence, Italy, at the beginning of the eighties by the work of Vincenzo Silvestri who designed and developed the original project.
The intents were that of providing the photographers of architecture, indoor and outdoor, with a wide angle camera extremely compact and light-weight, compared to the large view cameras produced in that period, and with the essential movements for the perspective correction.

The first camera, the SLV, was born with the 6X7 / 6X9 format, with a rotating back with click stop each 90 degrees and the lens, a Super Angulon 5,6/47 mm in focusing helical mount by Schneider

 , was not interchangeable. The shift mechanism permitted a total rise or fall of 25 mm, it consisted in a control knob and two counter posed screws right/left and allowed a precise setting and locking of the shift.
The attachment of the roll film back was Graflex compatible that opened the system to the application of various backs like Mamiya, Horseman, Wista, etc. The image viewing and the focusing were made on the round glass by mean of a magnifying lens in a leather bellow.
The whole camera structure was made in anodized aluminium worked with CNC machineries, ensuring constructive exactness and reliability.

From a conceptual point of view the SLV camera allowed to shift in any direction by simply placing and levelling the back horizontally or vertically and by orienting the camera body leaning it to the right or left, or upwards or up side down.
Some samples of this first model were made in an almost handcraft way but meeting a good interest among the specialized photographers, Silvestri was pushed to develop a new and improved model of SLV.

This second model had a bayonet for attaching the lenses and an interchangeable system for the backs.
This gave the SLV a major extension and flexibility and the range of lenses grew to 3 Schneider Schneider

 lenses: Super Angulon 5,6/65 mm, Super Angulon 5,6/75 mm and Symmar 5,6/100 mm, beside the Super Angulon 5,6/47 mm, all lenses had a bayonet attachment and a focusing helical mount. The interchangeable backs allowed to insert the extension rings to compensate the difference in focal distance among the various lenses. The 4 points of 8° attachment, quick and precise to use, also accepted backs of different formats like the 6x12cm and the 4x5”.

These modifications opened to the SLV new fields of application and attracted other photographers from Italy and abroad. The SLV will be substituted by the T30 camera in 1997, The T30, having 30 mm of shift movement, was more suitable to the new lenses with lager image circle

 that were introduced on the market in that period. The T30 is still in production.

A further step towards the flexibility of use consists in the design and production of the shiftable viewfinder with interchangeable frames. The viewfinder is extremely useful for quick works and in difficult work situations compared to viewing the image on the round glass.

S4

The S4 camera was designed later to answer the need of full coverage of the 4x5 inches format, where the SLV camera could not give enough versatility with this format. Standard 4x5 inches back with format adapters for 6x9 and 6x12, interchangeable backs with short rotation attachment 8° and bayonet attachment or interchangeable lens boards for the lenses. Large in dimension, it is later on provided with a front bellow (Flexibellow) that performs the lens focusing, tilting and swinging. With this accessory the lenses can be used without focusing mount and permitted the focus extension on the two orthogonal axis by using the lens tilting and swinging. The S4 camera is still in production.

Bicam

With the arrival of digital photography and considering that it would substitute le film in a short time, Silvestri began to study a camera able to face the double need of working with film but at the same time can be converted back to digital applications. There were two possible solutions, the scan backs or the matrix ones. The choice selected the matrix backs, creating a compact, easy to carry, proportioned to the small size of the high resolution sensors. Two series of Rodenstock

The Bicam introduced in the late nineties was added with new accessories and components so to follow the continuous evolution of the sensors’ technology. Its main characteristics are the possibility to work with lenses mounted in helical focusing mount and bayonet, or with a bellow system which add to the camera all the necessary correction movements typical of view cameras; side shift, rise and fall, tilt and swing; all movements are extremely precise and micrometric.
The reversible and interchangeable backs have a large range of accessories, from the sliding adapters with viewing screen and drop-in plates to interface the most popular digital backs: Hasselblad

S5 Micron

Classical view camera.
Designed for studio photography, it has full micrometric movements. All the parts related to lenses and backs are interchangeable. The lenses are on board or on bayonet, le lens boards are flat or recessed, the lenses have no need of helical focusing mount. The backs and their accessories are in common with the Bicam system. The bellow is interchangeable. The peculiarity of the S5 micron is to be built on two separate shifting blocks that do not interfere between them allowing the two standards to get to touching. This characteristic make it possible to use extreme wide angle lenses and to perform adjustment movements otherwise impossible. The S5 camera was published in the ADI Index 2005 for the industrial design award the Compasso d'oro
