The Rodenstock 105mm f/5.6 Apo-Sironar digital Lens is a standard view large format lens specifically designed for use with digital backs, which require a smaller image circle with extreme resolution, color correction, and maximum performance at a large aperture. This lens is recommended for use with backs having a maximum image area of 72 x 96mm, providing a view similar to that of a 38mm lens on a 35mm format camera.

In many cases, digital photography is superior to conventional photography if the desired end product is a printed image. To achieve this ideal, however, a much higher demand is made upon the image reproduction quality of the lens. This is because of a digital image chip's smaller area, which means finer details in a scene are squeezed into a smaller image recording area, as well as their sensitivity to color fringes.

But Rodenstock's digitally-specific lenses such as this Apo-Sironar digital provide image quality which allows the maximum capacity of a digital back to be realized. The lens utilizes every technological possibility to get as close as possible to the absolute limits of diffraction-determined resolution, even accounting for the properties and thickness of a CCD's protective glass. With the Apo-Sironar digital, you can use digital backs with a pixel pitch as small as 5µ.

This lens is recommended for use at apertures of f/8-11; you should primarily use your camera's movements to control the depth of field. Given its 105mm focal length (which allows plenty of space) and because it benefits from superior optical design without any needed concessions for an SLR camera's mirror box, this 105mm Sironar's commonly adapted for use with DSLR cameras. Its remarkable resolution can produce results impossible to achieve with an SLR system lens.

        Comments about Rodenstock 105mm f/5.6 Apo-Sironar digital Lens:

        I use this lens in combination with a Horseman LD and Canon 5D for tilt/shift panoramas.

        I have limited experience with this combination, but it appears that even with tilts (1 degree), I can back shift my 5D the full 30mm the Horseman allows (using up to 48mm of the image circle radius of 62.5mm) and see essentially no light fall off, details as sharp as the center, and no chromatic aberration (no red fringing of bright objects, no blue fringing either). Of course the vignetting due to the deeply recessed Canon sensor (40mm down in a straight sided box) needs to be covered up during stitching (use Photoshop), but the match will be essentially perfect, requiring only a minimal amount of blending.

        Trying to focus using the Canon view finder and the Horseman focus rack and pinion is a real challenge, in part b/c the Horseman could be a little more sensitive, and in part b/c f/5.6 is a little dark. f/4 would be easier for us 35mm folks.
