In its most recent iteration, the EOS C300 Mark II, the C300 has been subjected to a comprehensive redesign. The C300 Mark II appears to be identical to the original C300 at first glance; yet, appearances may be misleading. This is, in fact, an entirely brand-new camera. The C300 was the inaugural model in Canon’s Cinema EOS lineup, which it debuted with.
It recorded HD MPEG-2 at a rate of 50 Mb/s and 8 bits to CF cards. Because of its innovative new form factor, it was well suited for handheld use in a run-and-gun fashion. The 300 was succeeded by the higher-performing C500, however in order to take full benefit of high bit rate 2K and 4K recordings, an external recorder was required because the CF card continued to place limitations on the capabilities of the onboard recorder. The entry-level C100, which records in AVCHD to SD cards, was recently added to the lineup of products.
The first generation of the Canon C300 was designed with the creation of long-form television, such as documentaries, in mind. On the other hand, the codec restricted the possibilities in situations when the shots required intensive color grading and post-production effects.
Over the course of those intervening years, formats have evolved, most notably the standardization of ultra-high definition (UHD), which features a broader color gamut and an expanded dynamic range. The C300 Mark II adapts to the changes that have been made to standards, most notably Rec. 2020.
By switching from MPEG-2 to AVC level 5.2 compression, the camera is now able to handle the greater bit depths required for high dynamic range (HDR) recording, as well as 4:4:4 RGB, which is perfect for color matte shots.
The camera is capable of capturing a color range that is quite broad, including Canon Cinema, which is a wide color space that emulates film stock. The output can be generated as DCI-P3 (digital cinema), BT 2020 (ultra-high definition), or BT 709 while staying within the confines of this area (HD).
- Memory cards with the CFast format This allows for an internal recording rate of over 400Mb/s, which also supports 4K capture
- a new 4096 x 2160 sensor that supports 4K/2K film resolutions as well as UHD/HD (the original camera had a 3840 x 2160 sensor)
- a Canon Log2 transfer curve to assist HDR recording, with Canon claiming a dynamic range of 15 stops
- a battery that can record for up to 40 hours on a single charge.
- And brand new dual DIGIC DV5 processors to back up all of these functions.
