SmartAlign Drop-In Lens Mount for iPhone, M-Series / iPhone 16 / 16 Plus

Moment SmartAlign Drop-In Mount (M-Series, iPhone 16/16 Plus) — The Budget Lens Mount, With a Real Trade-Off

The gist: The cheaper M-Series lens mount fitted for the iPhone 16 and 16 Plus, worth knowing that Moment itself flags this older-generation mount as capable of softness or vignetting on newer phones — a real trade-off against the pricier T-Series option.

• SmartAlign bayonet: a glass-filled polymer mount built for precise, repeatable optical alignment when swapping lenses on the go.
• M-Series generation: designed for the iPhone 13-and-older lens lineup, sold here specifically fitted for the 16/16 Plus body.
• Known image-quality caveat: Moment's own spec notes M-Series mounts "may produce softness or vignetting" when paired with newer iPhones like the 16.
• Requires a Moment Case: it replaces the bezel on a Moment Case for the 16/16 Plus and does nothing on its own.

PetaPixel's coverage of Moment's lens lineup confirms the ecosystem is proprietary — lenses only mount through Moment's own case and bayonet system, regardless of generation.

Best for: budget-conscious travelers who already own older M-Series Moment lenses and want to keep using them on a 16/16 Plus. Skip it if: image sharpness matters most to you — the T-Series mount avoids the vignetting risk. Runs ~$5 — check the current price before buying.
