Owners and purchasers of the Canon EOS C300 Mark II can now benefit from a new lens mount service option which offers the capability to change the 4K Digital Cinema Camera’s original EF mount to EF Mount with Cinema Lock or to a PL mount and back again.

The Lens Mount Replacement service can be booked in at the Canon Regional Competence Centers (RCC) in France, Germany, Italy, Sweden or the UK. Alternatively, the PL lens mount and SHIM kit are also available for direct sale.

The recording coder bit-rates (up to 410Mb/s) and bit-depths (10 and 12) would qualify the camera for R.118 Tier 1, for both HD and UHD. The sensor size qualifies it for Tier 1 but UHD requires full resolution (3840×2160) in each of RG and B. Therefore the camera can qualify for Tier 1 in HD but only for Tier 2 in UHD.

Noise levels are good, the camera easily qualifies for Tier 1 in HD, and for Tier 2 in UHD provided the Canon Log 2 setting is used. With noise reduction set at not more than 5, the qualification holds up to ISO6400 (30dB gain), and the levels of aliasing drop virtually to zero. Dynamic range is very good – the Canon Log 2 settings deliver up to 15 stops, Canon Log delivers about 13.5 stops, BT.709 delivers about 11 stops.

Although the correspondence between ISO and Gain settings sets the base level of 0dB gain at ISO 200, the specifications refer to ISO 800 when dealing with noise and sensitivity. At ISO 800 and 1/50 shutter, the sensitivity is between F/10 and F/11 when using BT.709 preset, F/10 for Canon Log and F/9 for Canon Log 2 – this is to produce 50% video level with 18% reflectance lit at 2000 lux.

Infra-red response is negligible.

Motion portrayal can be affected by the ‘rolling-shutter’ scanning, but is a problem only with very short shutter durations.

Overall, the camera qualifies for R.118 Tier 1 in HD and Tier 2 in UHD.
