Ricoh's 360-degree camera — the Theta Z1 with dual 1-inch sensors for premium VR content.
The Ricoh Theta Z1 is the flagship model in Ricoh's Theta 360-degree camera line, introduced in 2019 as a professional-grade spherical imaging device. The 19GB variant specifies the internal storage capacity. It uses larger sensors than any previous Theta model to achieve significantly improved image quality for professional 360-degree photography and virtual tour applications.
The Z1 uses a dual 1/2.3-inch CMOS sensor system with four-lens optics to capture complete 360-degree spherical images at approximately 23 megapixels equivalent resolution, supports RAW+JPEG capture, records 4K 360-degree video, and connects via WiFi, Bluetooth, and USB-C. The 19GB internal storage accommodates extended shooting sessions.
The 1/2.3-inch sensors represent a significant upgrade over the smaller sensors in consumer Theta models, delivering meaningfully improved dynamic range and low-light performance. RAW capture enables professional post-processing of spherical imagery. The Z1 is a preferred choice for real estate, architectural visualisation, and immersive content production requiring 360-degree documentation.
Carefully inspect both lens domes for scratches — the protruding front elements are extremely vulnerable and any damage will appear prominently in the final 360-degree output. Test stitching seam accuracy by checking the horizon seam on a flat test surface. Verify WiFi and Bluetooth connectivity with the Ricoh Theta app. Check battery condition and charge acceptance.
