Shutter Priority
Hold shutter; the solver picks the matching aperture.
Where to find it
Viewfinder Priority Mode chip Shutter
Summary
Pick your shutter, let the meter pick the aperture. The motion-first workflow: you choose how to render movement (frozen action, motion blur, panning) and the app finds the f-stop that matches the scene EV.

How it works
What it does
Switch the priority chip to Shutter. Pick the shutter speed you want (e.g., 1/1000 to freeze a sprinter, 1/30 to pan a moving cyclist, 1/8 for handheld low light with deliberate blur). The meter holds that shutter and varies the aperture to match the scene's EV.
When to use it
Anytime motion rendering is the variable that matters most: sports and street where you need to freeze action, panning shots where deliberate horizontal blur is the goal, handheld in low light where you have a hard floor on shutter speed before camera shake takes over.
What the solver does
The solver computes the aperture from scene_EV and your fixed shutter, lands on the closest standard or custom f-stop, and warns if the answer is past your lens's actual range. With a fast lens (f/1.4) you get more headroom in low light; with a slow zoom (f/5.6) the solver may need to push ISO instead.
Long-shutter handling
If the chosen shutter is past your camera's slowest mechanical step, the solver hands off to Bulb mode (see 1.4a) and pairs the recommendation with the Bulb Timer (1.5) for the actual countdown.
