Can the Sony A7 lock an auto-set exposure in Manual mode?

On a Sony A7, is there a way in Manual exposure mode to meter once, automatically set the remaining exposure value, and then keep that setting locked until I choose to meter again?
For example, I want to work in Manual so shutter speed and aperture stay where I want them, but I’d like the camera to meter a scene, set ISO automatically, and hold that exposure rather than changing continuously as the framing changes. Is there a button or custom setting for this on the A7?

No. This is a function of some cameras, most notably those of Pentax, yet these are the exception rather than the norm.

Yes—on some A7 models, you can do this in Manual mode by using Auto ISO with AE lock.
Set the camera to Manual exposure mode and ISO to Auto. Then either:
- enable AEL w/ shutter so a half-press meters and locks the Auto ISO value, or
- use the AEL button/leverage to lock exposure manually.
In this setup, shutter speed and aperture remain where you set them, and the camera adjusts ISO to match the metered scene. Once AE lock is engaged, that ISO value is held until you meter/lock again.
Without Auto ISO, there is no general one-button “auto set exposure in M mode” feature like some other brands offer. The closest equivalent on the A7 is this Manual + Auto ISO + AE lock workflow.
