Canon is poised to add 24 and 25 frames per second movie recording to its EOS 5D Mark II in a bid to deliver the ?optimum frame rate for cinematic video?.

The move reflect a growing market for high quality movie recording in DSLRs.

Firmware update 2.0.3, available for download from ‘mid-March’, was developed following calls from photographers and cinematographers, according to Canon.

?The addition of the new frame rate expands the camera?s video potential, providing filmmakers with the ability to shoot 1080p Full HD footage at 24fps (actual 23.976fps) ? the optimum frame rate for cinematic video.?

The firm adds: ?25fps support at both 1920×1080 and 640×480 resolutions will allow users to film at the frame rate required for the PAL broadcast standard, while the new firmware will also change the 30fps option to the NTSC video standard of 29.97fps.?

The firmware update also adds a new histogram display for shooting movies in manual exposure, shutter priority and aperture priority.

Exposure modes will also be available when the movie option is chosen, plus manually-controllable sound levels using a sound level meter.

The firmware will be available at
