The lens decides the zoom story
Suppose the camera is fixed beside a miniature scene and the operator wants a tighter view without reaching over the display. RMT-P1BT has a zoom control, but Sony’s Help Guide makes its boundary explicit: optical zoom requires a camera or lens with electronic power zoom. If the camera’s digital zoom is enabled, the remote can operate digital zoom instead. It cannot turn a mechanically operated zoom ring into a powered lens.
A switch changes the same pair of buttons
The ZOOM/FOCUS switch assigns the plus/minus buttons to the intended task. That can be a useful physical arrangement for someone moving between supported zoom and focus control; it also means the switch position matters whenever the buttons appear to do the wrong job. Sony notes that zoom speed depends on the camera or lens. Do not choose it on the assumption of one universal smooth zoom rate.
A remote rather than another receiver
The connection is Bluetooth, with no separate receiver to place on the camera. The product also provides shutter/record control, AF-ON and C1 functions and a lock switch. These features make more sense for a camera already configured for the session than for someone expecting a miniature menu screen in their hand.
Who should put it on the shortlist
RMT-P1BT is a relevant candidate for a supported Sony camera whose operator repeatedly needs those controls away from the body. Confirm the exact camera and any required firmware before choosing it.
For a manual-zoom lens and a session needing only an occasional still photograph, its zoom buttons are not a reason to add it. The camera’s existing supported trigger method may already do that smaller job. Buy the remote for a control you can name, not for a lens function the camera does not have.
