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.[5] Still photography during video recording is possible, but the camera suspends recording video until the final still frame is captured.[6]

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.[7]

Video recording

The 5D Mark II is the first DSLR to feature 1080p video recording.[8] The Canon PowerShot SX 1 IS followed with full HD in a bridge digital camera soon after.[9] 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[10], leading to concern about Moiré patterns in recorded video.[11]

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.[12] Video clips are recorded as Quicktime MOV files with H.264/MPEG-4 compressed video and uncompressed PCM audio at 44.1 kHz. HD and SD bitrates are approximately 38 and 17 mbps respectively.[13] 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.[14]

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, but it currently only has a 30p video mode. PAL countries use a 25p mode and cinematic directors use a 24p mode. However, Canon does have plans for a firmware upgrade to add 25p and 24p capability.[15]

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.[16][17]

Problems

Early buyers of the camera reported black pixels appearing in high contrast situations.[18] In late 2008, Canon officially acknowledged that there was an issue with black dots and vertical banding noise in certain circumstances.[19] On January 7, 2009, Canon released firmware update 1.0.7 to address these two problems.[20]

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 [21].

Lettris

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.

boggle

Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
