Canon Might Release A Cinema Camera With RF Mount, In The Distant Future [CW1]

Eos C100 Cinema Camera

Rumor has it that Canon may have a Cinema camera with RF mount in the works.

However, such a camera isn’t to be expected before 2021, or even later. I have no idea if the RF mount is anything that would make something special out of Canon’s Cinema cameras.

Honestly, I don’t think we will see such a camera anytime soon, if ever.

Canon EOS C300 Mark III (and other stuff) To Be Announced Ahead Of NAB 2019?

Canon EOS C300 Mark III

Canon might announced two new Cinema EOS cameras ahead of NAB Show 2019.

One of these new Cinema camera will most likely be the replacement for the Canon EOS C300 Mark II (we reported back in November 2018), while the other camera is rumored to be a high frame camera.

It’s also suggested that the Canon EOS C300 Mark III will might have sensor upgrade option for 8K video. This will most likely be a paid upgrade, apparently to keep the initial price competitive (we reported). 4.4.4 codec and electronic image stabilisation will likely be on board.

Along with these cameras Canon might also announce a CN-E 100mm cinema prime lens

Firmware Update for Canon Cinema EOS C200/C200 Cameras

Cinema EOS C200

Canon released firmware ver. 1.0.5.1.00 for the Canon Cinema EOS C200/C200B cameras. You can download the firmware here.

Firmware Version 1.0.5.1.00 incorporates the following enhancements and fixes:

  1. A Continuous Recording function has been added allowing for nonstop recording.*1
  2. Peripheral illumination / chromatic aberration correction has been added for the following lenses:
    – EF Cinema Lens: CN-E20mm T1.5 L F
    – EF Lens: EF 70-200mm f/4L IS II USM
  3. For LUTs that can be applied to output footage, official support for the ITU-R BT.2100 standard and ITU-R BT.2408 report have been added for the following terminals:.
    – SDI terminal
    – HDMI OUT terminal
    Changes have been made so that the [HDR: PQ] and [HDR: HLG] base luminance corresponds to Diffuse White (100%) being 203nits*2.
  4. Support for the [Reset] function that resets the clip number when the reel number is set, has been added.
  5. When using an assignable button, the White Balance setting will be maintained after the power has been turned off.
  6. Fixes a phenomenon that occurs on cameras with firmware versions 1.0.3.1.00 to 1.0.4.1.00 in which resolution appears to be reduced in SD card recordings and in external outputs when shooting with specific menu settings*3.

*1 When using the continuous recording function, only MP4 format / 1920×1080 resolution is possible.
*2 The HLG output is the brightness in the case of displaying on a 1000nits monitor.
*3 Specific menu settings:
– When [Resolution/Color Sampling] is set to [3840×2160 YCC420 8 bit].
– When [Resolution/Color Sampling] is set to [1920×1080 YCC420 8 bit], and [Slow Motion Recording] is activated.
– When [Resolution/Color Sampling] is set to [1920×1080 YCC420 8 bit], and the digital tele-converter and EF-S lens correction are activated.

For further information, please refer to the latest version of the unit’s Instruction Manual that is released with the firmware update.

Canon Patent Application for a 11-440mm f/2.1-4.1 Cinema Zoom lens

Canon Patent Application

Canon patent application (US 20180143412) for what looks like a 11-440mm f/2.1-4.1 Cinema Zoom lens.

From the patent literature:

Conventionally, four-unit zoom lenses are often used as zoom lenses for television cameras because it is relatively easy to achieve a wide angle of view, a high zoom ratio, and size and weight reduction. Such a four-unit zoom lens includes, in order from the object side, a first lens unit having a positive refractive power that does not move for zooming, a second lens unit having a negative refractive power that moves during zooming, a third lens unit for correcting variation in the image plane caused by zooming, and a fourth lens unit having a positive refractive power for imaging.

In recent years, there have been proposed zoom lenses for television cameras including three, four, or more movable units as zooming units with functions as a variator and a compensator.

[…]

Thus, the present invention has an objective to provide a zoom lens including three or more movable units as its zooming units and simultaneously achieving a wide angle of view, a high zooming ratio, size and weight reduction, and particularly high performance in the focal length range from the wide-angle end to the zoom middle position. The present invention also aims to provide an image pickup apparatus having such a zoom lens.

To attain the above objective, a zoom lens according to the present invention includes, in order from an object side to an image side, a first lens unit having a positive refractive power that does not move for zooming, a second lens unit having a negative refractive power that moves during zooming, a third lens unit having a negative refractive power that moves during zooming, a fourth lens unit having a negative refractive power that moves during zooming, and a relay lens unit having a positive refractive power and being located closest to the image side that does not move for zooming. The second lens unit moves to the image side from a wide-angle end to a telephoto end. When a focal length fx determined based on a focal length fw of the zoom lens at the wide-angle end and a zoom ratio Z is fx=fw×Z0.38, the zoom lens satisfies 0.05<L2min/L2w<0.98, where L2min is a minimum distance between the second lens unit and the third lens unit in a zoom range from the wide-angle end to the focal length fx, and L2w is a distance between the second lens unit and the third lens unit at the wide-angle end.
