Parallel Shift

¡1

The lens is shifted perpendicular to the optical axis relative to the bayonet mount and so also relative to the taking format by rotating a knurled shift- ing knob at a shaft which is elastically flexible to protect against its damage or injury to the user.. The lens tube can be rotated continuously to the left or the right in a rotary mount so that the parallel shift can be made in any desired direction.. It is best to grip the lens at the flattened part with the millimeter scales for this purpose.. 45° latch steps ensure a precise vertical or horizontal parallel shift as required..

The maximum path of ¡1 mm at both sides can be utilized to the full in the shift direction of the short image edge (vertical in landscape format and horizontal in portrait format) if the camera is stopped down to at least f/8.. On a shift in the direction of the long image edge (horizontally in landscape and perpendicular in portrait), low vignetting of the image corners oppo- site to the shift (= of objects on the same side of the shift because of the upside-down image) may occur over the last half millimeter.. It is therefore recommended only to utilize the shift path up to 10..5 mm here and to stop down to f/¡1 with more than 9 mm to avoid this vignetting in critical motifs..

The noticeable latch step at 9..5 mm should not be exceeded diagonally even at f/¡1 with parallel shifts since then the image corner decentered the most will contact the image circle edge (see image on page 9)..

PC-SUPER-ANGULON 28 mm f/2.8 specifications

The Schneider Optics PC-Super-Angulon 28 mm f/2.8 is a remarkable wide-angle lens designed specifically for large format cameras, making it a favorite among landscape and architectural photographers. Renowned for its exceptional sharpness and striking image quality, this lens embodies the precision and craftsmanship associated with Schneider optics.

One of the standout features of the PC-Super-Angulon is its perspective control capabilities. The tilt and shift function enables photographers to manipulate the plane of focus and alter perspective, effectively reducing distortion in architectural photography. With a tilt of ±8° and a shift of ±12 mm, users can achieve remarkable control over their imagery, allowing for the creation of natural-looking images without the typical converging lines seen when photographing tall structures. This feature is particularly advantageous in minimizing the effects of perspective distortion and maximizing depth of field.

The lens offers a fast maximum aperture of f/2.8, providing excellent low-light performance and allowing for more creative depth of field control. The optical design comprises high-quality glass elements that ensure outstanding sharpness across the entire frame while delivering rich color rendition and contrast. The lens features a multi-coating technology that significantly reduces flare and ghosting, making it ideal for shooting in challenging lighting conditions.

Measuring 80 mm in diameter, the PC-Super-Angulon is compact for its class, making it relatively easy to transport while offering superb performance. Its robust construction ensures durability, which is essential for photographers working in various environmental conditions. The lens is compatible with a range of large format camera systems, emphasizing its versatility.

Additionally, the Schneider Optics PC-Super-Angulon employs a circular diaphragm, which enhances bokeh quality and contributes to the aesthetic appeal of out-of-focus areas. This characteristic is essential for achieving beautiful, soft backgrounds in portrait photography, setting it apart from traditional wide-angle lenses.

In summary, the Schneider Optics PC-Super-Angulon 28 mm f/2.8 distinguishes itself through its combination of advanced perspective control, exceptional optical performance, and a user-friendly design tailored for large format photography. Whether capturing sweeping landscapes or intricate architectural details, this lens delivers an unparalleled photographic experience, making it a valuable addition to any serious photographer's toolkit.
