Canon's compact full-frame RF Cinema EOS — a 6K back-illuminated stacked sensor in a C70-style body.
The Canon EOS C80, announced in September 2024, slots the full-frame 6K back-illuminated stacked sensor from the EOS C400 into a compact body closely resembling the C70. It is an RF-mount cinema camera that launched at around £5,200-£5,500 body-only in the UK.
The 6K BSI stacked sensor brings a triple base ISO of 800/3200/12800 in Canon Log 2, internal 12-bit Cinema RAW Light up to 6K 60p, and 4K up to 120p, recorded to dual SD cards. Unlike the C70 it adds a 12G-SDI output alongside HDMI, retains the motorised built-in ND unit and twin mini-XLR inputs, and runs Dual Pixel CMOS AF II with subject tracking. Rolling shutter is markedly better than non-stacked rivals.
Its significance is bringing C400-grade full-frame image quality, triple base ISO and SDI into the owner-operator class, effectively replacing the C70 as Canon's mainstream single-shooter cinema body.
Used examples are recent, so prioritise ones with remaining warranty and an original receipt. Exercise the electronic ND across its range and check for banding or stuck stages, confirm the 12G-SDI BNC is tight and outputs cleanly (rack and OB use can wear it), and test both mini-XLR channels. Ask what the camera was used for: PTZ-style locked-off streaming duty can mean high power-on hours despite a mint shell. Verify triple base ISO switching behaves in Log 2 and that firmware is current, and check the SD slots pins since 6K RAW workflows see frequent card swaps.
