EOS 7D Firmware 1.2.5 REMOVED

Today Canon UK has removed firmware version 1.2.5 for the EOS 7D from their website.

Yesterday we wrote an article about this new release available for download. Pretty weird it was only available at Canon UK. But even more strange that it was removed less than 1 day after we posted about it!

As we mentioned earlier, there was another weird thing: version 1.2.5 referred to a previous version (1.2.4) that was not widely (if officially) released.

We wonder… was a bug found on it?

Did Canon change their mind and are willing to add new features like disabling AGC to give manual audio control? (very unlikely to happen even when it’s so easy, but we all hope so)

Still no answers. So far, the “new” firmware version 1.2.5 is not available anymore.

EOS 7D Firmware Update 1.2.5

UPDATE: April 20, 2011 – Firmware version 1.2.5 for EOS 7D was removed from Canon UK. Check this article to know more.

Canon has released a new firmware update for the EOS 7D . It includes some fixes and improvements, but there is still no option to disable AGC (auto gain control).

Weird indeed, this firmware refers to a previous version (1.2.4) that was not widely announced. Moreover, this new version 1.2.5 still doesn’t appear on Canon USA website at the time of writing this article.

EOS 7D Firmware Update 1.2.3


Today Canon has released a new firmware update for the Canon EOS 7D.

Firmware changes:

Firmware version 1.2.3 incorporates the following fixes.

  1. Fixes a phenomenon in which the settings of the Speedlite Transmitter ST-E2 revert to the default settings when both the camera and the ST-E2 are set to auto power off.
  2. Fixes a phenomenon in which the Macro Ring Lite (MR-14EX, MT24-EX) and slave flashes do not sync while shooting wirelessly.

Firmware version 1.2.3 is for cameras with firmware up to Version 1.2.2. If the camera’s firmware is already Version 1.2.3, it is not necessary to update the firmware.

Note that cameras with the version 1.2.3 firmware (and also versions 1.2.0 through 1.2.2) cannot be downgraded to a previous firmware version (such as version 1.1.0 or earlier).

Important: Before downloading the firmware update, please be sure to read the entire contents of Canon’s page.

Official Download: http://web.canon.jp/imaging/eosd/firm-e/eos7d/firmware.html


This update is aimed to fix some issues, which is great and always very much appreciated for all Canon users, especially those ones suffering the issues.

But we can’t give up on asking Canon: why don’t they also IMPROVE some of the functions of their current expensive cameras?

This not only applies to Canon EOS 7D, but also to the rest even more expensive models like EOS 1D Mark IV and EOS 5D Mark II.

We don’t only want to see new cameras “replacing old” models (which in fact are not really “old”, that’s mainly a marketing crazy race) then “forcing” customers to buy new ones, but also firmware updates that give to the users and customers the HUGE potential these cameras ALREADY have inside.

We always like new cameras, of course, but we do not like the crippling that is applied to them, at all. Stop crippling cameras and “free” the current ones!. We are all customers and consumers, but not fools.

As a reminder we mention very few examples of features that CAN be improved on many current Canon DSLR cameras via Firmware Update (without hardware change):

  • “Clean” HDMI / AV output (function to enable/disable the white focus square in Live View mode. So easy to do)
  • Auto ISO Limiters, essential for M mode (in normal & Live View mode) (*)
  • Manual Audio gain control (*)
  • More frames available on Bracketing mode (for HDR photography)
  • Capability to “Edit” movie/video clip in camera (*)
  • Movie “Crop” mode (*)
  • etc.

(*) Notes: Some of these features are already available on specific models, while not in others sometimes much more expensive. Also, some of them are even available on P&S cameras under $500, but NOT in muti-thousand dollaras DSLR cameras!. This inconsistency and incoherence should be fixed by Canon.

Please check the article Zoom H4N – Firmware Update 1.70 (which indeed implements improvements) for more details, and also check the List of Fixes & Improvements to know more possible enhancements. It’s even smart from a business point of view (as commented on the previous link).


We have received LOT of messages from 5D Mark II and 7D users asking if there is a hope for such improvements. We couldn’t tell for sure. It all depends if Canon is willing to implement them or not (even when they actually CAN).

We sincerely hope Canon will “listent to customers” once again, and fix this inconsistency and incoherence, and improve the higher level DSLR cameras’ features to match the entry and mid-level ones.

Feel free to spread this link and support this “reminder” to Canon (of course, feel free to send it to Canon too using the contact information on the main page or your own personal way).

60D Features Request


  • Update #1 – Canon 60D Manual
  • Canon EOS 60D Features Request
  • Additional Comments



The english user manual for the new Canon EOS 60D is now available for download. You will notice that there is no AF microadjust in the manual.

Download it from here:  Canon EOS 60D Manual (.PDF)

This camera looks very promising indeed, and great to use as a second body or complementary to the 5D Mark II (keeping in mind the 60D is a crop sensor HDSLR).

Despite the AF micro adjustment is not necessary at all for movie recording, we hope a firmware update will add this feature for still shooters.


The new Canon EOS 60D seems to be a very promising camera for the entry-level segment, and even as a second body for many serious amateurs or professionals.

Canon Rumors has posted today an article about something we do also support and want to share with the Canon community:

The 60D Needs AF Microadjustment

No Microadjustment in the 60D

I just learned today that there is no AF microadjustment in the 60D. There is a great thread on the forum about it.



Read more here.


As with every Canon DSLR we encourage all users to request to Canon to give the full potential of their cameras to their customers.

You will find the Canon contact information on the sticky post at the main page of this blog.

We support all possible improvements that CAN be achieved via Firmware Updates, like lot more that are still possible to the Canon 5D Mark II and the rest of the HDSLR line (check Canon Firmware Updates). Some features are essential, and many are even very easy to implement.

Soon we’ll publish an article based on a very interesting comment posted by a reader. Stay tuned.

Malfunction in Firmware 2.0.4 UPDATE


  • Introduction
  • Video Tests
  • Additional Feedbacks
  • Considerations


For a full detailed report, please read our previous article.

We have been receiving additional reports from other users regarding the malfunction we found on Firmware 2.0.4: the “IRIS jitter”

Not all lenses are affected. This phenomenon occurs much more often with Macro lenses, but it is NOT limited to Macro lenses.

Please note that this is a firmware issue, not a lens issue.

How to reproduce the issue

As we explained in the previous report, it is very easy:

Set camera to M mode, Live View to “Stills+Movie – Movie Display“, which is the correct mode to get “full manual control” on movie mode. Then turn ON Live View mode and rotate the focus ring, and you will notice the iris jitter watching it directly or watching the image on the camera’s LCD, also hearing the noise of the iris.

Remember the camera is now in “full manual mode” for movie/video mode, so the iris should not change “at all” unless the user intentionally does change it.

Clarification of the issue: It is not the iris/diaphragm is closing or opening a step and remaining there. It is a jitter: a fast open/close or close/open movement of the IRIS, mostly depending on the direction the focus ring is being rotated. It usually occurs in small values (1/3 f-stops), with the consequence that the image is also suffering that “jitter” when recording a video clip (or even when not recording), making the footage unusable.

Important note: the IRIS jitter is NOT related to the amount of light being gathered by the sensor, nor being metered by the camera, because the same issue occurs in a dark room or with the lens cap on.


Thanks to the users who made their video tests and sent the links to us.

▪ With a Canon EF 100mm f/2.8 Macro USM lens:
Image jitter can be seen on the camera’s LCD monitor lot of times
It’s also recorded on the footage, making it unusable. It is much easier to see whilst testing or recording than in this video test. The most evident ones at 0:48, 0:57, 1:01, 1:03:

▪ With a Canon EF 300mm f/4L IS USM lens:

▪ With a Sigma 150mm f/2.8 Apo Macro:

▪ With a Canon EF 100mm f/2.8 Macro USM in a dark room:

For obvious reasons we can’t post a video showing the issue, but those users who own this lens can do the test in complete darkness, following the instructions, and then hear the iris jitter lot of times.

Note: this test can also be done with the lens cap on with the same results.


Some feedbacks from readers regarding this issue with other lenses:

Canon 300mm 2.8L IS USM:

“Canon 300 2.8 IS + 1.4x TC – does it pretty much every time you cycle focusing from around 20m to infinity position
Canon 300 2.8 IS – does it at times, a bit randomly, not every time, seems to occur a bit more toward the near focus end”

Tamron SP Di  90mm 1:2.8 Macro:

“Firmware 2.0.4 iris jitter malfunction on Canon 5D Mark II tested also with the following lens in FULL manual mode (iris jitter appears nearly EVERY time when rotating the focusring, so it is totally unusable):

Tamron SP Di  90mm 1:2.8 Macro”


We are only reporting a malfunction with the sincere hope it will be fixed at some point.

We do understand the HUGE efforts made by Canon engineers with the latest firmware update, and we are really grateful for that.

This is a great chance for Canon, not only to fix this issue, but also to add some of the features improvements hugely requested by thousands of 5D Mark II users around the world. We have already mentioned them in our previous report (click here).

We love this extraordinary camera and we want the best for it, that’s why we put very big efforts on everything related to the 5D Mark II, because we know its huge potential.

We are confident this issue will be fixed and possibly some features added too on a new update, for the benefit of all Canon users.

We sincerely thank Canon for listening to customers and being steps ahead far of competition.

Malfunction in Firmware 2.0.4


  • Malfunction in 2.0.4 – IRIS issue
  • Video Tests
  • Test Update
  • Additional Reports – UPDATED
  • Considerations

Note: please also check the update to this report.


Firmware 2.0.4 is really a GREAT update, an extraordinary effort made by Canon engineers. But after some deep tests we have found and confirmed a bug/malfunction in this firmware.

▪ Description of the problem:

When a Canon EF 100mm f/2.8 Macro USM lens is mounted on the camera and the user manually changes focus (rotates focus ring), the lens suffer from an “IRIS jitter”, even when the camera is in full manual mode.

It is not normal, and should not happen. The tests were made by several users with many copies on many camera bodies, so it’s not an isolated lens problem.

This malfunction always occurs in this situation:

When the camera is set to M (Manual) mode and in Live View mode (set to Still+Movie – Movie Display), which is the correct mode for “full manual control” in movie mode.

Additional details:

. It does NOT happen with Firmware version 1.1.0
. It happens WHEN recording video and also when NOT recording video
. It happens with ISO and every possible automatic setting fixed to a value, or turned off
. It happens in C1/C2/C3 too (if they are registered as “M” modes for movie recording)
. It happens in PAL and NTSC modes
. It happens in  both lens modes: MF and AF mode
. The camera does NOT tell any change in aperture setting (it keeps showing the same value) nor give any kind of advice either
. The iris shifting can be heard (and seen)
. The brightness shifting of the image is visible on the camera’s LCD monitor when the iris/aperture shift occurs
. The iris/aperture usually changes in small values, but enough to make a footage unusable, so using this great lens for movie/video purpose may result impossible


These two videos clearly show the problem when the Canon EF 100mm F/2.8 Macro USM is mounted on the 5D Mark II in the full manual mode for movie mode, and the focus ring is rotated from macro to infinity and vice versa. Remember that this does not happen with firmware 1.1.0.

Iris “jitter” when changing focus:

▪ Image jitter can be seen on the camera’s LCD monitor lot of times
It’s also recorded on the footage, making it unusable. It is much easier to see whilst testing or recording than in this video test. The most evident ones at 0:48, 0:57, 1:01, 1:03:

Please read full descriptions on each video for further details.


We made another simple test to prove this issue is not related to the light entering the lens/sensor/camera: If you reproduce the test, with everything set to Manual as described but in a dark room, the same issue occurs (you can hear the iris jitter when changing focus).

Conclusion: the IRIS jitter is not related to light metering or any kind of “compensation” being done by the camera due the different amount of light entering the lens when focusing, nor any other light/sensor related matter.

Since the test is done in complete darkness we cannot post a video to show it, but every user can reproduce and verify it by their own with ease.


We received some additional reports from many users.

Some of them:

– Regarding the malfunction of the Canon EF 100mm 2.8 Macro USM:

“By observing the IRIS as I adjusted the aperture I noticed that sometimes it doesn’t go correctly to the right size. I even noticed that sometimes as I stopped down the aperture for a step the IRIS would actually open a bit instead.”

– Other reports: We also received reports regarding 3rd party lenses experiencing “weird noises” coming from the iris, or iris/aperture inconsistencies when mounted on 5D Mark II with firmware 2.0.4 that weren’t present on firmware 1.1.0.

It seems very possible that these issues also occur with some 3rd party lenses and maybe other Canon lenses as well.


– We received a video test from a user reporting this iris “jitter” on a Canon EF 300 F/4L IS USM
Check it here: http://www.youtube.com/watch?v=APgK5gdM69M

The user confirmed the camera was set to M and Live View mode to “Sills+Movie-Movie Display”, which is the correct “full manual mode” for video, where “the camera shouldn’t be moving the iris *at all* unless the user is changing it”.

This confirms that this malfunction also affects other Canon lenses when using firmware 2.0.4 on the 5D Mark II.

It might sound weird, but we wonder if this issue could be related to the supposed fix:
“Fixes a phenomenon where communication between the camera and the attached lens is sometimes interrupted after manual sensor cleaning. (This phenomenon only affects units with Firmware Version 1.2.4.)”.


We understand that this firmware update is a VERY hard work. But maybe there weren’t given enough resources to support this extraordinary effort made by Canon engineers.

That may explain the initial undetected bug/malfunction on version 2.0.3 (that was reported just 1 day after its official release by many professionals and by this team who use 5D Mark II for serious movie/video purposes).

We use Canon gear and we love this camera. That’s why we try to do our best in the most constructive possible way to encourage Canon to give the best features and results to their customers.

We want the best from this extraordinary camera, for every user, and also the best for Canon as company for making it possible.

We request Canon to fix this problem. That’s the priority.

But we also request Canon to carefully read and consider what so many customers are asking: to include some additional functions that are really possible and even easy in many cases.

The 5D Mark II has been a huge success since its release. This could be a great opportunity for Canon to add these features and keep it as a best seller for even longer time.


AutoISO limiters, so much requested by photographers (like the much cheaper Canon T2i/550D)
More frames in Bracketing mode
Movie Crop function, to allow video recording at 1:1 of the central area of the sensor (at the highest possible resolution: Full HD, HD or at least in SD like the much cheaper Canon T2i/550D)
▪ “EDIT” function in playback menu, allowing to Cut and Save part of a video clip (available in most cheaper cameras)
An OPTION to display Audio meters bars in Live View mode and when recording video
An OPTION to disable the “white square” when using HDMI output, to get a “clean” video output (so easy and so requested), and keep that signal at the maximum possible resolution when recording video
More flexibility for the “Info” button in Live View mode (more display options: current Live Histogram is great but it’s only displayed with extra information, reducing the overall frame visibility)

These are hugely requested functions that CAN be implemented via firmware. They don’t require hardware changes.

For a longer and more detailed list, please check this article.

We sincerely want to thank Canon for listening to their customers and being steps ahead of the competition.
