Sony LYTIA 610: 64MP Sensor With Hybrid Pixel Architecture That Could Fix Smartphone Telephoto Cameras

Sony Semiconductor Solutions announced the LYTIA 610 on June 24, 2026, positioning it as a specialized sensor for telephoto cameras in smartphones rather than primary wide cameras . It is a 1/2-type CMOS image sensor with approximately 64 effective megapixels and a pixel size of 0.7μm, with mass-production shipments scheduled to begin at the end of June 2026 .

The RB2×2 On-Chip Lens (OCL) Pixel Architecture

The defining feature of the LYTIA 610 is the RB2×2 OCL pixel structure, which Sony describes as the industry's first mass-produced sensor with this design . The architecture addresses a long-standing trade-off in compact sensors: the conflict between maintaining high spatial resolution and achieving fast, reliable phase-detection autofocus.

Rather than using a single lens structure for all pixels, Sony splits the job:

• Green pixels use a 1×1 OCL structure, where each green pixel has its own microlens. This helps preserve spatial resolution and fine detail in the luminance channel .
• Red and blue pixels use a 2×2 OCL structure, with four pixels sharing one microlens. This arrangement provides phase-detection autofocus data with higher signal strength and faster focusing performance .

Sony developed dedicated array conversion processing (remosaicing) to reconstruct the final image output from this hybrid layout . The company says this approach reduces the resolution penalty associated with conventional 2×2 OCL layouts while retaining strong autofocus performance .

Improvements Over the LYTIA 601

Sony directly compares the LYTIA 610 with its earlier 0.7μm-pixel design, the LYTIA 601. The company states that the LYTIA 610 delivers more than a 20% improvement in spatial resolution compared with the LYTIA 601 . This improvement comes from the hybrid OCL design, which is intended to reduce the resolution penalty associated with conventional 2×2 OCL layouts while retaining strong autofocus performance .

Video and Still Capture Capabilities

The LYTIA 610 supports 4K video at 120fps, enabled by improved readout performance . Sony achieved the readout speed increase through finer process technology for the logic circuit and parallel optimization of the AD converter, resulting in a data readout speed approximately twice that of the previous generation . This makes it Sony's first 1/2-inch sensor to support 4K 120fps recording .

For still capture, its approximately 64MP resolution is intended to support higher-detail image capture in compact mobile camera modules . The sensor also supports 4K 60fps HDR video for high-contrast scenes . Hardware interfaces include both MIPI C-PHY and D-PHY for high-speed image data transmission .

Target Smartphone Segment: Telephoto Cameras

The LYTIA 610 is specifically aimed at telephoto cameras in smartphones rather than primary wide cameras . Reports consistently describe it as a telephoto-oriented sensor designed to improve zoom-camera image quality and autofocus . Its high resolution is especially relevant for telephoto use, where cropping and detail retention are important . Sony's goal with the sensor is to narrow the quality gap between main and telephoto cameras .

Market Positioning Alongside the LYTIA L910

The LYTIA 610 and the LYTIA L910, announced one week apart in June 2026, occupy different roles in Sony's mobile imaging lineup based on their specifications and stated imaging priorities .

Feature	LYTIA 610	LYTIA L910
Announced	June 24, 2026	June 17, 2026
Target role	Telephoto / zoom camera	High-dynamic-range mobile image sensor
Format	1/2-type	1/1.28-type
Resolution	Approximately 64 MP	Approximately 50 MP
Pixel size	0.7μm	1.22μm
Key tech	RB2×2 OCL pixel structure	LOFIC structure + Triple Conversion Gain HDR
Dynamic range	Not specified as headline feature	100 dB single-exposure HDR
Video	4K 120fps	4K 60fps
Shipment	End of June 2026	Summer 2026
Positioning	Compact telephoto sub-camera sensor	Larger high-dynamic-range mobile sensor

The LYTIA L910 is a larger-format 1/1.28-type mobile image sensor with approximately 50 effective megapixels . It features LOFIC technology and Triple Conversion Gain HDR to achieve 100 dB dynamic range in a single exposure .

The LYTIA 610, by contrast, is a smaller 1/2-type sensor optimized for telephoto sub-cameras in smartphones . Its key selling point is delivering higher resolution and improved autofocus in a compact format .

Together, the pair suggests a two-pronged Sony mobile imaging strategy for 2026: the LYTIA L910 emphasizes high dynamic range for larger mobile camera modules, while the LYTIA 610 brings a novel pixel architecture to telephoto cameras .
