EDITING CHANGES
Page 6: “low signal-to-noise ratio” was changed to “high signal-to-noise ratio.”
Page 11: (EOS 5D Mark II vs. EOS-1Ds Mark III) “EOS-1Ds Mark II” was changed to “EOS-1Ds Mark III.”
Page 15: “…the narrow depth of field of the EF85mm f/1.2L II USM lens…” was changed to “…the narrow depth of field that’s possible with the
EF85mm f/1.2L II USM lens…”
Page 18: “Video are recorded…” was changed to “Video clips are recorded…”
CLARIFICATION
This White Paper document includes the following statements in reference to depth of field control in movie mode with the EOS 5D Mark II:
Page 6: “With [movie mode] activated, photographers and videographers can capture high definition video with depth of field control found only
in professional models.”
Page 14: “[The EOS 5D Mark II] is lighter, smaller and lower priced than most professional HD camcorders, yet provides amazing depth of field
control…Until now, there were no affordable 1080p HD video camcorders…that had the depth of field control found in the EOS 5D Mark II.”
Page 22: “The full-frame, 35mm ‘film’ size of the EOS 5D Mark II’s sensor…improves depth of field control with normal lenses compared to
APS-C sensor cameras, with dramatic DOF control when shooting HD video.”
Page 77: “Alternatively, professional videographers will be drawn to the EOS 5D Mark II’s unique depth of field control [in movie mode]…”
This White Paper document also includes the following statements:
Page 18: “When shooting videos…[e]xposure is controlled using Program AE…”
Page 19: “Program AE is used for exposure control with all video recording.”
The White Paper’s references to “depth of field control” may have inadvertently confused some readers who equate that term with manual aperture
control. However, the EOS 5D Mark II does not provide manual aperture control in movie mode. As noted above, the White Paper states that
“Program AE is used for exposure control with all video recording.” Program AE is a fully automatic exposure mode that does not allow manual
aperture adjustment. Even without manual aperture control, depth of field in movie mode with the EOS 5D Mark II can be controlled, in the sense
that it can be made narrow or deep depending on the user’s choice of focal length and subject distance. These two factors apply just as well to the
EOS 5D Mark II as they do to any other camera or camcorder. Another way that EOS 5D Mark II users can control depth of field in movie mode is
through the camera’s AE lock function, which can prevent the aperture value from changing.
Perhaps more importantly, with the EOS 5D Mark II’s large image sensor and its ability to use very fast lenses, users can obtain shallow, selective
depth of field that is difficult or impossible to achieve with regular camcorders with smaller image sensors. This sensor size difference means that,
for any given combination of aperture value, subject distance and angle of view, images from the EOS 5D Mark II will have shallower depth of field
than images from a conventional HD device. EOS 5D Mark II users can take advantage of this feature to produce high quality HD movies.
Canon is gratified at the overwhelmingly positive market response to the EOS 5D Mark II camera. Based on this success, it’s only natural that
advanced users are looking for manual aperture control in movie mode, and Canon is listening to constructive comments and feature suggestions.
In the meantime, we hope that our comments here will help to clarify the White Paper’s statements on depth of field control in movie mode.
