[9] Dimensions: Width of image 180 mm, width of camera: approx. 138 mm. [10] NOTE: one should prefer aperture 10.0 or 11.0 to provide room for a slight focus overlap on this 42 Mpixel sensor even if the desired rotation value of 0.5 mm is sometimes involuntarily exceeded. A close scrutiny reveals that the combination of aperture 9.0 and a manageable 0.5 mm lens rotation doesn't quite suffice to establish an overlap if the desired rotation value is inadvertently exceeded (e.g. by 0.7 mm = 40%) over a slightly slanted area. |
