EOS 5D Mark III Firmware 1.2.1 Available for Download

[leGreve]

Wauw... they really dropped the ball on this firmware upgrade. What a complete waste of time and hype.

I know it's mainly a still camera, but hey, those so-called video upgrades are worthless.

Magic Lantern is doing better things for the 5D than Canon themselves.
I guess that is just what Canon is about.

Well now someone else is insisting that the 1.4x TC III + 70-300L + 1DX doesn't report f/8 or AF well so maybe I got bogus info at first. Maybe there is no way to make that combo report f/8. A huge shame, but what can you do, sounds like you can't blame the firmware after all.

(Although they could add a custom function called force f/8 AF mode hint hint ). Not that I expect that to happen. Usually companies with more than 4 employees don't do that sort of stuff. But it would be awesome (and boost Canon TC sales vs Kenko hint hint ))

I guess I'll order the Kenko (apparently it has a chip inside that can spoof things or something and tricks it into reporting f/8 even though the 70-300L doesn't have TC pins) and hope the image quality it provides is enough to make it worthwhile.

To bad the Canon TC III didn't have some fancier logic in it to spoof things when needed or a force f/8 mode custom function is unlikely.

Anyway guess they didn't remove stuff from the f/8 addition so it's all good on their part. Glad we have f/8 ability for what it does handle .

Unless I hear otherwise yet again.

Correct me if I'm wrong, but I thought a phenomenon was something amazing and hard to explain, rather than simply being a software bug or a hardware shortcoming.

Magic Lantern is working on a true RAW and 14 bit video recording along with 4:2:2 to the card, something we'll never see from Canon.

And they've already said it will never be something that will work for video people...best they've gotten so far is 720 at 24fps for 2s...the reality is you'll never get long recording times because the camera has a buffer to deal with. 1080p wont happen.

Really, it's an upgrade for time lapsers and may have some cool other uses.

If this is the case, the soft output of the 5DmkIII compared to other cameras, as documented on many of his tests, may in fact be impossible to fix with a firmware update, at least one from canon.

That said, what they did find interesting was that the resolution of the DNGs they got from their RAW mode were way higher resolution than just the traditional h.264 video stream from Canon. Not sure if that means that Canon intentionally is crippling it, or if the h.264 encoding loses a lot of resolution, but, that could be useful for some purposes.

Of course, if you want Raw video at 2k, you'd just spend the same amount on a BMCC instead and get a much nicer workflow.

I wonder if they can feed that 'raw' DNG stuff into the h.264 compressor and get better quality out? Or if they can push it out frame by frame over the HDMI and delete each frame from the buffer afterwards so nothing would ever overflow and you could at least get an 8bit or maybe 10bit crisper image out over HDMI? It seems like it should be possible but it's hard to know the internal Canon subsystem, it might not be, or even if it is, it quite likely might require all sorts of knowledge far beyond what they have been able to hack out so far and might only be reasonably doable by Canon people with full docs and access?

I checked out the DNG file posted on eoshd.com. Each file is about 5MB. Therefore, to get 30fps, you need a sustained write bandwidth of 150MByte/s (that is 1.2Gbits/s). That will be quite challenging even for the fastest notebook SSD. A 64GB CF card, even if it were fast enough, would only store about 7 minutes of video.

Therefore your suggestion to use the HDMI out is potentially the solution. HDMI 1.0/1.2 supports a bandwidth of 4.95Gbit/s and HDMI 1.3 supports about 10Gbit/s. BTW, does anyone know which version of HDMI is supported by 5D3?

Ofcourse, I am no camera engineer. These are just rough calculations that I came up with.

Lastly, pardon my ignorance in video, doesn't the 'uncompressed HDMI' output as provided by firmware v1.2.1 mean raw? Is the ML DNG just a higher resolution raw compared to the one provided by firmware v1.2.1?

Actually neither are truly RAW since they are debayered and binned in either case and somewhat processed. The 'raw' DNG ML found does retain 14bits though and 4:4:4 I believe, so it's sort of raw in that sense and seems to have had no NR or anything done and seems crisp.

1.2.1 send ucompressed out over HDMI but it is not RAW, it has been debayered, scaled to 1920x1080 and clipped to 8bits and 4:2:2 color information.

1.2.1 appears to retain more detail in shadows and is crisper (worse AA and artifacts are a question mark) whether recorded internally or externally.

That definition is phenomenal!! ;-)

NEWSFLASH: Canon fixed all observable occurences!!!

I guess my standards for "phenomena" are too high. :-(

[eyeland]

agreed
Too damn high

For those of us who use Canon batteries and don't care about video (the minority here I guess  ), the f/8 autofocus on a non-1D body is amazing and I couldn't be happier!  I can't believe that the AF is still so snappy at f/8 and can't wait to get out to shoot some wildlife

[Danack]

Went out shooting today with my 5DmkIII, 100-400 + 1.4 TC.

Works so much better with the new firmware compared with taping up the pins. It's actually even about the same speed as a 1DmkIII - but the focus spot seems so small, which is probably more due to the lack of crop factor rather than it actually being a smaller focus zone.

[Lee Jay]

Enables the center AF point to autofocus when the camera is used with Canon EF lens/extender combinations whose combined maximum aperture is f/8.

Question for owners.

Has anyone tried the f/8 AF system with f/2.8 lenses with stacked teleconverters?

Anyone?

[Zlatko]

Was hoping they were going to fix the black AF points to illuminate them. Had a really, really hard time a couple of nights ago doing some nighttime street photography. Frequently impossible to find the active AF point unless you turn the camera toward a light colored background.

AF Oneshot is a lot more accurate in low light...plus one can see which AF point is illuminated.
There's a vast array of different ways of using the AF system on the 5DIII, I'm sure with a little exerimentation a workable solution can be found for your style and genre of photography.

Someone please clarify:  does this firmware update change anything with the problem of AF points not being illuminated as they are on other Canon cameras?  It's not mentioned in the list of improvements.

I don't have full support on 3rd party batteries, but I still get accurate charge percentage...

Is the CF formatting after the firmware update really necessary, or removing the firmware file is enough?

Wondering about the same thing.

It isn't strictly necessary to format the CF (or SD) card after updating the firmware; you could just as easily remove the card from the camera, insert it into your PC's card reader, and there delete the firmware update file from the card.

I think Canon stipulates this instruction, as it's the simplest, safest and most straightforward method for ensuring that the firmware update file is removed from the card, and that the card is made ready for capturing more images / video, all without needing to remove the card from the camera.

When I put one of my cards into a card reader after capturing images to it, it has two folders, one containing images and a second named CANON_MISC (or something similar). I don't know if these folders are created during the format process, or when the first image is captured; I've never taken the time to check. But if they are created during the format process, it would be another reason for following Canon's recommended procedure, rather than, say, putting the card into your PC's card reader and formatting it there.

...
15. Removed "support" for 3rd party batteries...

16. Removed the unofficial support that was apparently left in the f/8 firmware improvement for the 1DX that let the 1.4x TC III work with the 70-300L (if you keep it at 300mm).    (Kinda ironic that they force you to sell your Canon TC and go buy a Kenko it seems or spend an extra $250 for a Kenko and, assuming it is not as sharp, not get the full performance you should be able to and need to get out of the 70-300L. Still hoping that they will put out a 1.2.2 with 'various minor fixes' and they will support this combo unofficially.) I don't have the 1DX but two people are telling me that they see it report as f/8 and work on their 1DX after they put in the f/8 firmware for that body. Canon removed it from the officially reported list (maybe since the TC only fits if you use it on the long end at 300mm) but apparently left the support code in on the 1DX and seemingly removed it when they took six months to otherwise perhaps copy and paste the code over the 5D3.

Although now 1DX users are telling me it doesn't work in that combo and, even worse, now a 5D3 user says it does't report or work with the Kenko either (hopefully this user was using a different Kenko). I don't know. Maybe I got bad info from people at first. I will try the Kenko myself and see what the real deal is. (if someone gives me a 1dx a will test that too and give a definitive answer )

Hi all,

I've been reading this forum for a while and finally decided to post something today... something weird :
Yesterday, right after the 1.2.1 firmware update, my 5D III set the micro adjustments to -8 (in the option for all the lenses). It was set to 0 before.
By the way, I'm not using the general MA option. I'm using specific MA per lens, which are set between +7 and  +10 depending on the lens mounted on the body.

That sounded weird to me so I made a couple of tests with my 50L. And it seems that my +10 MA settings lead constantly to out of focus pictures.
I made tests with MA set to 0 and even to -8 and it appeared to be much better !

So now I'm wondering what Canon meant by "Fixes a phenomenon in which the camera changes the AF microadjustment value to -8." ?

I'm testing my other lenses today...

Thanks for reading.
Bruno
