Guest Ebrahim Saadawi Posted February 2, 2016 Share Posted February 2, 2016 We already have a crowded topic for it so a listing of how the camera is in comparison to the market is essential. There are a few missing details in what's publicly announced but thankfully we have a dear Canon contact and as of last night the NDA has been lifted on the 1DX II information. -Camera shoots 4K video. 24p to 60p with full quality & sound. -It's only DCI 4096 x 2160. Canon reasoning is that users can crop to UHD but not vice versa.-It's not a full sensor readout. It's like the 1DC in 4K mode crop wise. -All HD modes even 120p are a FF sensor readout.-Up to HD 60P, is regular frame rate menu option. 120p is a dedicated slow-motion function activated in the menu, at which you get no sound recording and the conforming occurs internally.-4K modes are used with CFast slot activated. -4k 24p is Motion JPEG at 4:2:2 500mbps 8bit-4k 60p is Motion JPEG at 4:2:2 800mbps 8bit -How does the camera downsample to HD? Non-disclosed information. You can expect remarkable FF HD quality at all modes. -Are there aliasing/moire artefacts in 4K/HD modes?No. -Why MJPEG? Because while it requires large data pipeline it delivers class-leading compression quality. -Why not Canon's new XFAVC? Because the 1Dx line is built or absolute reliability and the XFAVC codec caused occasional overheating without the use of active fan cooling, which is not an option for weather resistance. -Why not normal H.264 100mbps like the rivals? Because it doesn't meet the 4K quality requirement for the camera's target user. H.264 4:2:0 All-i/IB-P only available in normal HD modes, as well as even lower bitrate options for instant sharing. Another reason why MJPEG was chosen is the identical image compression to Canon's normal JPEG engine, with the same quality for 8.8mp image extraction (available in-camera) to normal Jpegs in stills mode. -Sensor quality/image improvements? The sensor uses and entirely new on-chip ADC design, as well as micro-lens gapless design. The new chip offers marked improvement over the predecessor in high-iso performance and dynamic range that's applicable to still images and video mode. The sensor was designed for speed in-mind therefore allowed the 4k60/HD120 plus vastly improved rolling shutter performance on the video side.I can definitely confirm the 4K video image off the new sensor is the highest quality video of any Canon DSLR camera, in terms of resolution, dynamic range, lack of compression artefacts, and striking lowlight ability. The image reproaches that of current highest-end cinema cameras in a DSLR body, with AF and phenomenal stills performance. And a major point is that the 1DXII quality allows it to go places even the Cx00 cameras simply cannot due to the environment insistent body. Does it output 4K HDMI? No. HDMI output is HD 4:2:2 uncompressed. Exceptional quality is especially sen when the camera is set to shoot 4K with the corresponding cop. Capture of high quality HD back-ups during internal 4K recording is the achieved goal. -Dual-pixel AF same as 70D? No. Dual-pixel AF here is vastly improved. Its our first FF size image sensor to incorporate the technology. Over the 70D, the 1DXII offers full control over auto-focus behavior in terms of shifting speed (10 increments, 1 being slowest and suitable for on-film use, while 10 is much faster ad suitable for acquiring focus prior to recording),the speed of DPAF can be set separately for stills and video modes. In video-modes,AF can be set to manual subject choice (using the newly developed touchscreen) or face-tracking and the system will accurately follow the subject smoothly with zero failure rate as the AF is using more than 16 million points in DPAF as opposed to a few on-chip points .Dual-pixel auto-focus works in all video modes including 4K capture modes. What's the Canon view on the 1DC since the 1DXII has all these newer features at lower price? The EOS 1DC is still a part of the Canon EOS line-up. Why?Because some users can find C-Log a necessary function for easier matching of footage to other EOS Cinema line cameras (XC10, C100, C300 and C500). The 1DC does not have the 30 minute limitation which can be essential for a number of users. The 1DC also offers a slight wider FOV in 4K mode (1.3x vs 1.4x) and a unique S35 HD crop mode that inter-cuts with HD images from the C100/C300 in C-log with no effort. -The live-view mode is vastly improved, and with DPAF and 16fps speed, with the mirror locked-up the camera is a fully functional mirrorless camera.-Touch-screen functionality is only used in live-view mode to acquire focus points and not activated ANYWHERE else in the camera. -The LCD is markedly improved in quality with emphasis on easier manual focus and accurate exposure over the 1Dx/1Dc. No zebras/peaking.-The camera receives a headphone jack for audio monitoring & clean HDMI over the 1DX. The audio quality has been improved.-Canon is aiming the 1DXII at high-end cinema applications. ------------------------------------------------------------------------------------- Ebrahim: This is quite an exciting camera, and Canon rarely excites. A 1DC with major additions at 2000$ less.Please give the 5D a FF/APS-H 4K (MJPEG 500mbps 422 not a crappy h.264 100mbps 420 mode). Or will they keep the lovely 1DC/1DXII 4K to the +6000$ cameras? I sadly think so. Quote Link to comment Share on other sites More sharing options...
