Sony's broadcast-grade 4K camcorder with three 1/2-inch CMOS sensors, 17x optical zoom, and HDR recording.
The Sony PXW-Z280 was released in 2018 as a professional XDCAM ENG broadcast camcorder, featuring a three-chip design: three separate 1/2-inch back-illuminated Exmor R CMOS sensors, one per colour channel. This 3-chip architecture provides the colour accuracy and chromatic separation required for broadcast news and documentary production. 4K/60fps at 4:2:2 10-bit. Fixed 17x optical zoom lens (30.3-515mm equivalent). Approximate body weight 2.6kg.
Three 1/2-inch BSI Exmor R CMOS sensors (one per RGB channel). 4K/60fps at 4:2:2 10-bit; XAVC-Intra up to 600 Mbps and XAVC-Long up to 150 Mbps. Also records MPEG HD422 and DVCAM for legacy workflow compatibility. Dual SxS media slots. Fixed 17x optical zoom, 30.3-515mm equivalent, with independent focus/iris/zoom rings. Electronic variable ND filter. Dual XLR 4-channel audio inputs. 12G-SDI and HDMI outputs. Approximately 2.6kg body.
The 3-chip sensor architecture differentiates the PXW-Z280 from single-chip consumer and prosumer cameras: colour information is captured simultaneously on separate R, G, and B sensors via a prism block, eliminating the colour interpolation that single-chip Bayer sensors require. This provides the colour fidelity for broadcast chroma keying and colour critical applications. The electronic variable ND enables smooth aperture-maintained exposure transitions without the stepped ND rings of manual filter designs.
On the used market the Sony PXW-Z280 is available at professional broadcast camcorder pricing. Condition checks: 3-chip prism block integrity (critical — prism misalignment causes colour fringing), dual SxS card slot contacts, fixed lens zoom and focus ring operation, and 4-channel XLR input function. S-Log3 and HLG gammas are supported. Fixed 17x lens — no interchangeable mount.
