The Canon EOS 5D Mark II is a 21.1-megapixel full-frame CMOS digital single-lens reflex camera made by Canon. It succeeds the EOS 5D and was announced on September 17, 2008.[1] The 5D Mark II was the first digital camera used for an official U.S. Presidential portrait.[2][3]

Improvements compared to original EOS 5D

  • 21.1 megapixel (5,616 x 3,744 pixels), compared to 12.8 megapixels (4,368 x 2,912 pixels)
  • DIGIC 4 image processor, compared to DIGIC II
  • 100-6400 ISO (expandable to L (50), H1 (12800), H2 (25600)), compared to 100-1600 (expandable to L (50), H (3200))
  • 3.9 frames per second continuous shooting (78 JPEG or 13 Raw in a single burst), compared to 3 fps (60 JPEG or 17 Raw)
  • Small Raw modes: sRAW1 mode (10 megapixel/3861 x 2574 pixels), sRAW2 mode (5.2 megapixel/2784 x 1856 pixels)
  • 98% viewfinder coverage with 0.71x magnification, compared to 96% coverage
  • Larger 3.0-inch (76 mm) LCD display with 640 x 480 VGA resolution (307,200 pixels/921,600 dots), compared to 2.5-inch (64 mm)
  • 1800mAh LP-E6 battery, compared to 1390mAh BP-511A

New features

  • Movie recording with 12 minutes of full HD at 1920x1080, or 30 minutes of SDTV at 640x480 resolution, up to 4 GB, 30 frames/s (due to FAT32's limitations)
  • Monaural microphone for audio during video recording, speaker for playback and microphone jack for external stereo microphone
  • Live preview with contrast-detect autofocus
  • HDMI video output for live preview or playing clips and images on an external monitor via Type C MiniHDMI port
  • Dust reduction system to perform automatic sensor cleaning
  • Battery management software

The 5D Mark II is the first camera in the EOS line to provide video recording functions.[4] Still photography during video recording is possible, but the camera suspends recording video until the final still frame is captured.[5]

The Li-Ion battery for the 5D Mark II (LP-E6) has a 1800mAh capacity. Each battery contains a microchip with a unique identifier for reporting charge status and battery health for display on the camera. The 5D Mark II's 'Battery Info' screen can track battery health and shooting history for up to six LP-E6 batteries.[6]

Video recording

The 5D Mark II is the first DSLR to feature 1080p video recording.[7] The Canon PowerShot SX 1 IS followed with full HD in a bridge digital camera soon after.[8] The 16:9 aspect ratio portion of the sensor used in video mode is equivalent in sensitive area to a VistaVision 8/35 frame, even larger than the Super 35 frame of the much more expensive Red One camera. This large sensor allows videos to be recorded with very shallow depth of field for a "film look". The 21 megapixel sensor is downsampled to HD resolution by only using every third line and 4:2:0 chroma subsampling[9], leading to concern about Moiré patterns in recorded video.[citation needed]

Movie clips can be up to 4 GB in size, approximately 12 minutes of 16:9 HD (1920x1080) or 24 minutes of 4:3 SD (640x480) footage (depending on scene complexity). These limits stem from the 4 GB maximum file size supported by the FAT32 filesystem format used on Compact Flash cards. The camera also imposes a hard maximum clip length of 29 minutes 59 seconds if the 4 GB limit has not already been reached.[10] Video clips are recorded as Quicktime MOV files with H.264/MPEG-4 (Base Profile @ L5) compressed video and uncompressed PCM audio at 48 kHz. HD and SD bitrates are approximately 38 and 17 mbps respectively.[11] Although the internal microphone is mono, stereo audio is supported through the audio input jack. When recording for long periods, especially in warmer climates, increased video noise may occur due to CMOS overheating.[12]

Video functionality

The EOS 5D Mark II is capable of video recording in low-light situations and it is sold for a relatively low price. For the first eighteen months of its release, the camera only had a 30 frame per second video mode. On March 15 2010, Canon released a firmware upgrade to add a 25p mode for PAL format compatibility and a 24p mode for compatibility with motion picture film cameras.[13] The firmware update also modified the 30p mode to record 29.97 fps and the new 24p mode actually records 23.976 fps to have the same frame rate as drop frame timecode. Lastly, the update added manual control of the audio record levels and an official way to disable the AGC.

There is third party firmware for the 5D Mark II, similar to CHDK, that provides many additional video and cinematography related functions such as zebra stripes for exposure control, depth of field estimates, audio VU meters and disables the automatic gain control on the microphone input.[14][15]

Software

The included software package contains following software: [16]

Problems

Early buyers of the camera reported black pixels appearing in high contrast situations.[17] In late 2008, Canon officially acknowledged that there was an issue with black dots and vertical banding noise in certain circumstances.[18] On January 7, 2009, Canon released firmware update 1.0.7 to address these two problems.[19]

Originally the camera lacked manual control when filming video. On 2 June 2009 version 1.1.0 of the firmware was released which provided control over aperture, shutter speed and ISO while recording video [20].

On 17 December 2009 Firmware Version 1.2.4 was released to support the WFT-E4 II wireless file transmitter and to correct an issue where visible noise may appear in photos taken in continuous Bulb shooting.[21]

On 16 March 2010 Firmware Version 2.0.3 was released to support 1080p at NTSC 29.97fps, 1080p at PAL 25.00fps and 1080p at cinematography fps 23.976fps. It also added a function for manually adjusting the sound recording level (64 levels), an histogram display (brightness or RGB) for shooting movies in manual exposure, shutter-priority AE mode (Tv) and aperture-priority AE (Av) mode to the exposure modes for shooting movies and changed the audio sampling frequency from 44.1 KHz to 48 KHz. On 17 March 2010 the firmware was found to have some bugs with the audio functions and thus retired.[22][23] On 19 March 2010 Firmware Version 2.0.4 was released to solve 2.0.3 bugs.[24][25]
