NOTE: This image is a focus stacked image of "Sony Alpha 7R IV elevated front view with exposed sensor.jpg" consisting of 9 images that were merged using Zerene Stacker Version 1.04 Build T2021-02-16-2045 (licensed). As a result, this image underwent digital manipulation which may have included blending, blurring, cloning, and colour and perspective adjustments. As a result of these adjustments, the image content may be slightly different than reality at the points where the images were combined. This manipulation is often required due to lens, perspective, and parallax distortions.

[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. |
