    A useful tutorial that picks up a somewhat misleading statement from Hasselblad and propagates it:

    Because the calculation is carried out in image space, not object space, focus position and focal length of the lens don't affect the image plane step size.

    This is soooooooooooooooooooooo slow 200 secs for a stack 🙄 im shooting my stacks at 10 frames per sec using mechanical systems. electronic is
    just to slow.

    The time it takes depends on the selected settings (start delay, delay between shots, shutter speed).
    Sony has finally also implemented focus bracketing (a7rV). They are getting there, very slowly 😉.
