Description:
Because of its enlarged image circle of 62 mm, this lens can be shifted from the optical axis by up to 11 mm. Its special mount permits rotation in 45° steps to permit perspective corrections in vertical and horizontal formats. In this specially designed lens mount the aperture is set in accordance with the classic working aperture method. A preset lever facilitates stopping down the aperture to the pre-selected value. A floating element ensures high imaging performance into the 30 cm (12 in) near-focusing range. This special lens is unsurpassed for architectural photography because it eliminates the converging lines of conventional lenses (left illustration). Shifting its optical axis permits a stepless perspective correction until a pleasant natural overall image is achieved.
