The PCS ARSAT H(K) 2,8/35 (PCS = Perspective Correction by Shifting) camera lens is a wide-angle, eleven element large
aperture optical system, suited for producing extremely high quality photographs.
The PCS ARSAT H 2,8/35 (NIKON MOUNT) lens is designed for KIEV-19 and NIKON type cameras; The PCS ARSAT K 2,8/35
lens is for PENTAX cameras.
In terms of structure the optical block shifting mechanism is designed to provide the photographer with the power correct the image
distortions encountered during shooting architecture, panoramas, and products.
The optical elements of the lens have a special multi-layer coating (МС), they improve image quality and increase contrast range
by enhancing integral transmission and decreasing the dispersion.
The camera lens operates in the temperature range from minus 15 to 45° С.

- Page 2 4. OPERATIONS INSTRUCTIONS 4.1. Lens installation on the camera and its removal While superposing the indexes on the lens’ bayonet and the camera’s body install the lens on the body and turn it in the direction recommended in the camera’s operation manual, securing it in the usual fashion. To remove the lens take the bayonet’s knurled ring, press the camera’s latch and turn the lens up to the stop.
- Page 3 4.5. Distortion correction When photographing high buildings from ground level, the distances from the lens from the top and bottom of the subject are radically different. As a result of this, the distortion in this case appears as a convergence of the parallel lines upwards (Fig. 4), and vice versa: when photographing from above downwards, the parallel sides of the building will be converging downwards.
- Page 4 4.7. Panoramas While using a lens with shift capability you can produce panoramic photographs. For that, make two exposures from one camera angle: first one – with maximum shift of the lens to the right, and a second one – with maximum shift to the left. Combining both images will provide you with a single panoramic photograph (Fig.
