The Schneider 110mm f/5.6 Super-Symmar XL Lens is a professional wide angle lens for the 4x5 format, providing an angle of view on 4x5 which is similar to a 30mm lens in the 35mm format. For many, it is the ideal general use wide angle lens for large format, and this helps explain its scarcity in the secondhand market. The Super-Symmar XL lenses are the world's first aspherical lens design for large format, producing incredible peak sharpness with excellent correction for distortion and a small overall size. The 110mm f/5.6's very large image circle allows plenty of creative control for the photographer-in fact, it has the largest image circle of any 110mm large format lens. Beyond the coverage, the lens' large maximum aperture helps to ease the difficulty of focusing the camera in poor light.
The 110mm Super-Symmar XL's 105° angle of coverage permits a generous 76mm of all-direction shift on the 4x5 format, which is particularly beneficial when capturing a building from ground level. There are very few cameras, either field or view, which could offer enough displacement of the standards to challenge this lens' image circle limitations in 4x5. It can be mounted upon nearly view or field camera, thanks to its small 54mm diameter rear barrel which only extends 18.9mm behind the mount, allowing plenty of space between the rear of the barrel and the image plane for tilts and swings.
The 110mm Super-Symmar XL uses 67mm filters on the front, but can also use more compact 52mm filters upon the rear of the lens. For critical work with transparency film, it is recommended to use their dedicated #3b center filter.
