Sony's new 64MP sensor wants to make your phone’s zoom camera as good as the main one

Sony has launched the LYTIA 610, a 64-megapixel image sensor built around a pixel design the company claims nobody has mass-produced until now. Sony calls it the RB2×2 On-Chip Lens structure, and the whole point is to fix the camera most phones treat as an afterthought: the telephoto.

Shipments start at the end of June 2026.The target here is specific. On almost every multi-camera phone, the zoom lens lags behind the main one in sharpness and video. Sony built this sensor to shrink that gap.

How the new pixel design sharpens zoom shots

The RB2×2 OCL layout runs two lens arrangements on one sensor at the same time. A 1×1 setup chases fine detail, while a 2×2 cluster handles phase-detection autofocus. Add a remosaicing algorithm tuned for this exact arrangement and Sony claims a 20% bump in spatial resolution over its older sensor with the same 0.7-micron pixels.That number matters because zoom sensors have long made you choose between crisp detail and dependable focus. Sony's claim is that you stop choosing.

4K 120fps lands on a Sony sensor this size for the first time

The LYTIA 610 is also Sony's first 1/2-type sensor to shoot 4K at 120fps, which opens up proper slow-motion on a lens that almost never gets it. The credit goes to redesigned logic circuits and a reworked analog-to-digital stage that, together, double the readout speed of Sony's previous sensor this size.

There's 4K 60fps HDR too, meant for tricky scenes where bright skies and deep shadows usually wreck one or the other. The bigger idea is continuity. Swing between a phone's main and zoom cameras and the colour and clarity shouldn't visibly jump, and faster readout helps keep that handoff clean.The sensor measures 1/2.0-type, uses Quad Bayer colour filtering, and pushes data out over MIPI C-PHY and D-PHY. Whether any of this lands depends entirely on which phones pick it up.
