Camera

Epically
equipped

We've packed Galaxy's biggest sensor, light-absorbing pixels and video stabilisation technology into one Pro-Grade Camera, all resulting in the ultimate question: "Can you send me that?"

Camera Lens

Wow-worthy resolution

Resolution on the 200MP Wide-angle Camera has nearly doubled, delivering strikingly clear photos⁵. Zoom and crop your shots for a whole new view – or leave it intact for brilliant detail, corner to corner.

Nightography

Can you send
me that?

A Pro-Grade Camera grabs brighter photos and video, dusk to dawn⁶. The intelligent pixel sensor adapts to low light with Nightography and the camera lens tones down flare for clearer captures.

S Pen

Perfect precision

Have the power of an editing suite in the palm of your hand. The fine nib lets you create complex selection in your photos, trim videos with extreme accuracy and when you need to get in the frame too, control the camera remotely using the S Pen's button.
