This page discusses how the Nikon Z7 behaves with respect to aperture behavior when viewing vs when focusing vs when shooting.
There are several relevant camera behaviors that a photographer must know in order to achieve optimal sharpness, particularly when the placement of the zone of focus relative to the desired point of focus get sloppy.
- At which aperture does the camera show the live image in the viewfinder? It might be wide open, it might be the shooting aperture, it might vary by scene brightness, it might have a fixed limit, e.g., f/5.6.
- At which aperture does the camera focus? For example in an f/1.8 lens with the camera set to shoot at f/8, does the camera focus at f/1.8 or or f/8 or something else?
- Does the foregoing change under different conditions, such as very dim light or very bright light?
- Are there any camera settings which control or affect the behavior?
