1. GENERAL GUDIELINES 

 
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°
