Focus Bracketing Example @ 16mm: Failure to Reach INF, Aspen
Firmware version 2.00.
This focus stacking example looks at how the Sony A7R V focus bracketing feature fails to reach infinity focus (INF), which is engineering incompetence.
And thus requiring the photographer to manually focus and shoot a frame focused at INF, so that sharpness of the stacked image is excellent, instead of the badly blurred failure that the A7R V would have delivered. If one remembers to do so. Well, it’s a requirement with Sony.
Camera configured to shoot from starting position to INF, allowing up to 12 frames with the tightest spacing ("step width").
