Canon 5D MkIII gets clean 8-bit HDMI out in new firmware update

Yep, that’s right: Canon are finally accepting the fact that the still and video camera markets are slowly merging, and will add clean HDMI output to the 5D MkIII in a firmware update. Due in April, the update will also bring improved AF functionality, and there’s even 25p support coming to the 1D-C.

“When shooting video, HDMI Output makes possible the recording of high-definition uncompressed video data (YCbCr 4:2:2, 8 bit) from the EOS 5D MkIII to an external recorder via the camera’s HDMI terminal,” Canon’s press team inform us. “This, in turn, facilitates the editing of video data with minimal image degradation for greater onsite workflow efficiency during motion picture and video productions. Additionally, video being captured can be displayed on an external monitor, enabling real-time, on-site monitoring of high-definition video during shooting.”

All of which we think is pretty awesome. “It’s good to see the 5D return to the top of the pile,” says James Graham, our camera expert and resident 5D enthusiast. “The 5D handles high ISO shooting far better than the Nikon D800 and, although I haven’t got the chance to try out the Sony A99 yet, the 5D has the better sensor.”

AF to work up to f/8
Leading us further down the dark road that ends with cameras becoming sentient robots whose operators exist purely to give them the occasional light dusting, Canon are also enabling autofocus up to f/8. “Even when the EOS 5D MkIII is equipped with an extender and lens making possible a maximum aperture of f/8, the firmware update supports AF employing the camera’s central cross-type points (currently compatible with maximum apertures up to f/5.6). Accordingly, the update will allow users to take advantage of AF when shooting distant subjects, benefitting sports and nature photographers, particularly when using telephoto lenses.”

25p (and possibly 8K) for the EOS-1DC

Also due in an April firmware update is 25p support for the 4K-capable EOS 1D-C, meaning you’ll be able to use it to shoot content at the UK broadcast standard. Huzzah! There are also rumours that Canon plan to use the 1D-C’s super fast buffer to allow you to record short bursts of 8K footage. Admittedly, not many filmmakers will be interested in shooting six seconds of 8K, but if you’re using the 1D-C primarily as a stills camera, having the flexibility to capture those incredibly detailed video clips will be fantastic. Here’s hoping Canon confirm soon…
