Canon release C300 mkII firmware version v.1.0.4.1.00 with Canon Log3, viewfinder magnification during recording and Dual Pixel CMOS AF for CN7x17 and CN-E18-80mm lenses

Canon have just released new firmware that unlocks a lot of new features on the C300 mkII. The release, which was announced at NAB earlier in the year, brings the much anticipated Canon Log3 to the camera. There is an excellent write-up of how it works on the Abelcine website. In addition the new firmware also offers a reduction in noise levels of the existing Canon Log2.

A major fix is the ability to magnify the image in the viewfinder while recording – a serious omission in the original camera firmware and something that practically every competing 4K cinema camera could do.

Users of the EF mount version of the CN7x17 KAS cine servo zoom gain Dual Pixel CMOS AF with the firmware. This uses the servo motor on the lens grip to control the focussing (there are no internal motors in the lens). I haven’t yet seen how fast and accurate this. The same AF system is also implemented for the as yet unreleased CN-E18-80mm T4.4 which we looked at recently.

Another useful new feature is the ability to control the zoom of compatible Canon servo zoom lenses by using the jog controller on the camera handgrip.

Push auto iris and fully automatic aperture have also been added. There firmware is also supposed to alleviate the ‘black sun’ issue that some users have encountered.

These improvements will certainly be welcomed by users of the camera. Combined with the recent price drop they make the C300 mkII a much more attractive proposition than before. Whether this is enough to win over Sony or original C300 users in numbers remains to be seen.

You can download the firmware now from the Canon website.
