Canon Re-Releases 80,000 ISO Firmware for EF & PL C300 Cameras

C300Canon released a pretty hefty update for the C100 and C300 about two weeks ago, which included expanded ISO options all the way up to 80,000, as well as interface and button changes. Shortly after releasing the update for the C300, Canon pulled the download because of an issue with color balance after installing. They have now re-released that firmware with a fix for color balance on both the EF and PL C300 cameras:

Please note that we suspended download services for Firmware Version that was posted Tuesday November 12, 2013 due to a discrepancy in color balance. We would like to apologize for the inconvenience. Firmware Version corrects this color balance discrepancy. Any cameras that are running firmware version should be updated to firmware version

If you're wondering what the higher ISO settings look like on the C300:

And here's a great test on the C100 of the new ISO settings:

If you missed it, this is what’s new in the C300:

EOS C300 Cinema EOS Camera & EOS C300 PL Cinema EOS Camera

1. Ability to move the magnification viewing area around the LCD using the MAGN Function.

2. Support for a 1440×1080/35Mbps recording mode.

3. ISO up to 80,000 has been added.

4. Added functionality to support the optional Canon GPS Receiver GP-E1.

5. A Key Lock menu setting has been added which now makes it possible to lock all operations, including the START/STOP button.

6. Using the optional Canon WFT-E6 Wireless File Transmitter, the camera’s remote-control application allows two users to access the same unit via a Wi-Fi® link providing simultaneous camera operation and control and metadata input simultaneously.

7. [Lens Exchange] and [ND+/ND-] have been added as functions that can be allocated to any assignable button.

8. A new Wide DR gamma setting provides an expanded dynamic range of 800%.

9. Flicker Reduction has been improved.

EOS C300 Cinema EOS Camera only

10. Provides Push Auto Iris and One-Shot AF operation.

11. A new AE Shift function and the selection of various light-metering modes are now available when used with some Canon Cinema lenses (EF mount) and Canon EF Lenses.

12. Ability to assign the two control dials to operate either Iris or ISO sensitivity independently.

13. Peripheral Illumination Correction Data has been added for seven (7) Canon Cinema lenses (EF mount) and fifteen (15) Canon EF Lenses.

14. A function has been added to enable continuous focus and iris setting on a subject in the middle of the screen when one of the two EF STM lenses** is attached.

**[EF-S18-135mm f/3.5-5.6 IS STM], [EF-S18-55mm f/3.5-5.6 IS STM].

Apparently it was impossible to downgrade the firmware for the C300 if you'd already updated the camera, and it would have had to be sent in to camera to roll back the update. Now with the new firmware the issues should be solved, so if you've got a C300, head on over to the Canon site and grab version

It seems like Sony is really kicking Canikon's behinds in the mid-high camera range over the last year or so. For the Big 2, 2013 has been largely about updating the $300-$1000 market segment, whereas Sony came out with the RX 10 and A7 models, prosumer/pro 4K camcorders and the high end/pro 4K pieces. Under the normal circumstances, the two dominant players would have sat on their three year cycle concept but, these days, they have to respond or risk losing a tremendous percentage of their market share. Ideally, the entire Cinema series would have had a manufacturer type upgrade, similar to what has been offered by Sony for FS-700 or by Red for their Epic-Dragon switch. With smartphones already producing (highly compressed, yet still very sharp looking) 4K imaging, it'd be a shock not to see new 4K models from at least Canon in the sub-$5K territory. Supposedly, they will have at least one prior to the NAB'14 but, IMO, they need to update their entire line.
