Source? Link, please. It's nonsense because 80D will force UHS-III cards into UHS-I mode and some cards (Sandisk ...) will be outperformed by fast UHS-I cards. See www.cameramemoryspeed.com

Just checked the video files from my 80D and it looks like the video bitrate peaks at about 92mbps, the 70D is about 42mbps. Would we have to take into account the buffer too?
Canon recommend using a UHS3 card for video to cope with the higher bitrates.
Based on this, I would hazard a guess that the 80D is twice (if not a bit more) as fast as the 70D in terms of writing to the card.

I can repeat the bug over and over on one SD card with both IS lenses but there is no bug for either lens when I use a different SD card. I switched to using the SD card without the bug even though its just a 8gb card.

Any news regarding the issue? Since there's been no replies for a good while I assume not, but as an EOS M owner myself too, I'd of course like to see this get solved. I would love to have focus peaking!

It seems weird that the bug appears also when TL is not loaded but the loader is used to fire up canon's code. The thing that with the 11-22mm objective fully extended always manifests the problem and fully retracted (storage position) doesn't, tells it very likely has something to do with the lens initialization and it might be very sensitive to timing at the first power on of the camera. I assume with the 11-22mm it's almost the same there was no lens installed if it's retracted.

How much does the configuration with minimal autoexec.bin add to the startup time? How long does it take from the power-on to the jump to canon code with TL versus without TL?

Could it be just that Canon's code works with pure chance, the code is just magically waiting at the correct location / done some required initializations if only clean Canon firmware is used? When TL adds a bit of code to the startup, the lens has done it's own stuff before Canon's code reaches some point it should've been at a few milliseconds before and thus won't work.

I might possibly find the answer to the next question by searching a bit, but I'm just going to ask.. Is the power to the objective hardwired or can it be controlled from the software? Could the objective power on command (or some other thing that tells the lens it is attached) be removed from the startup of Canon firmware and make TL command it after everything else has loaded properly?


Edit: Just an idea, if the above would be true, it could mean that with clean firmware, no TL, the bug could be reproduced by having the lens a bit loose, powering on, and very quickly (almost simultaneously) turning the lens so it gets contact. Could be almost impossible to get the timing right of course..

From testing it appears the bug is more to do with the SD Card.

I have been thinking about this bug. Why some have it and some dont. I am swayed to think its something to do with the SD card. Looking at the variables. The camera body is virtually the same between users, so we should see the same results across all EOS M bodies. The same applies for the lenses. However the version of TL we use can be different per user. However most of us test for the bug using the same version. Some folk having the bug and some not having the bug. The one big variable is the SD cards we are using. Ill put money on it that if we all did a poll most of us would be using different cards.

Now, in the light of the fact that I have had this bug from day one and no version of TL or ML has managed to stop it happening. I used a brand new 8gb sandisk card straight from the packet and blam. Bug is non existent. I would say that after all the testing the bug lies with something to do with the SD card. If you experience the bug with either the 18-55 or the 11-22 try a different SD card with the same build. See if the bug goes away.


on a side note i just spotted thi from here about the 11-22mm

Quote
With its existing firmware the EOS M can't recognise when the lens is in its retracted position, and will allow the shutter to release. Canon recommends updating the firmware to the co-announced Version 2.0.0 for full compatibility, which as a bonus promises faster autofocus with all lenses.

I know it has nothing to do with the bug but its an interesting fact that they had to fix something related to shutter release.

@1%

Does the bootflag running under firmware update do the exact same change/flag to SD cards as eoscard?

It appears the shutter bug may have something to do with the SD card.

No luck Gary. Now Ive had a good play with a new SD and a used SD could it be something to do with the EOS_DEVELOP and BOOTDISK flags on the SD cards. I have no bug with a brand new card and the bug with an older card, even after formatting etc.

Ok, i have some great news. Just tried the nov 01 build on a brand new sandisk 8gb card and have no shutter bug with the 18-55mm. However! I still get the shutter bug with the 32gb card I have in my camera with this build.
The only difference between the cards. The 32gb card did have eoscard run on it ages ago to allow tl to run on the older fw.

How can I format and remove all flags etc from the 32gb card that had eoscard run on it? This way I can check if its eoscard thats causing the problem.

Whoop. Possibly a step closer!

Malakai, I am just curious if you still have the shutter bug? I have not had it now for almost two weeks.

I havent tried a recent build but still have an older build with the bug. Ive been using the 22mm for a while so didnt need the 18-55mm but its still in my camera bag just in case. I will have a go with a new build in a bit, see how I get on.

I dont think its anything to do with EosCard.
I only used EosCard once on a 512mb SD card that I used to test TL on my EOS M on FW 1.0.6. After that it was all done in camera. I never used EosCard at all when fw 2.0.2 came out and still have the shutter bug. Even on brand new cards.

If you open raw images in canons Digital Photo Professional click the image and press Ctrl + I (on a windows machine) it will show you all the details attached to the raw image. Including the Picture Style you had chosen when the image was taken. You can also see this if you have the tool window open. Under the RAW tab below white balance adjustment.

Sensor clear does the fast power cycle at the end so clears the bug. Same as turning it off and back on again, but its slower to do sensor clean.

I meant over-complicating in how this bug occurs. I think everyone on this thread is trying to help find a solution to this bug. I have it bad, it effects all of my ef-m lenses and its only on a much older build of TL that I can use my 22mm with TL without having the bug.
Ive been testing many solutions with a!ex the past few weeks to try and narrow down where the bug is occuring but as he said this bug is like looking for a needle in a haystack and a similar bug on another camera took nearly a year to find.

I was trying to clarify that the bug only occurs when running ML/TL. It doesnt occur when ML/TL isnt running, great information for people who are reading this thread and trying to figure out if they should run TL or not.

IMHO you guys are over-complicating this bug.
It only occurs when ML/TL is installed or running.
When the bootflag is disabled ML/TL is not running unless you used the non-bootloading version.
If you dont have bootflag installed or have not run the non-bootloading version then you wont have the bug as you are running default canon firmware.

Here are the facts.

  • Installing any version of Magic or Tragic Lantern can cause the shutter bug to occur with any EF-M lens.
  • There have been no reports that the bug effects lenses using the EF-M adapter.
  • Running with the bootflag enabled means your camera will boot Magic/Tragic Lantern first then Canon firmware and can cause the bug with EF-M lenses
  • Running with the bootflag disabled means your camera only boots from the Canon firmware. As Magic/Tragic Lantern is no longer running the bug wont exist.
  • Enabling and Disabling the bootflag is as simple as runnng the firmware updater again and changing the mode dial to enable or disable the bootflag.
  • There are two ways to clear the bug when running Magic/Tragic Lantern. Do a quick power cycle or just rotate the lens while powered to break contact between the lens and body.
  • There are some people not experiencing the bug while running Magic/Tragic Lantern with different EF-M lenses. This could be due to many factors.

I tried your steps exactly three times, then variations on your steps. including low level format and using different cards. still no luck.

Alex and 1%,
You asked for ways to replicate the bug and I think I have found a way. I also figured out how to get rid of the bug. I mentioned here the other day I did not have the bug again. I added the modules one by one and I eventually had all the modules loaded and I still did not have the bug. Even after typical use of the camera recording raw and taking pics using the EFM 18-55mm lens.

I got the bug again last night when I used the USB cable to transfer files and load picture styles. When I unplug the USB, the camera would not shut off as I have mentioned here before. I have replicated that using the USB will always add the bug. 

I got rid of the bug by using Canon Clear All Settings and then Canon format, but, keep the ML files on the card option and do not use the low level format. After the format, reboot the camera and then the bug goes away. All the ML stuff was still loaded and working. I have replicated this procedure as well.

 I am using the latest Oct 15th version. The bad thing is I then lose the exfat format I had on the card. The Canon format always returns it to Fat32.

Gary

This clears the shutter bug?

Can you guys to a little test for me?

- Note down the "release shutter without lens" setting (under custom functions)
- Try to take a picture. If it fails change the setting to a different value

Repeat a couple of times. The question is wheter that setting does somehow re-initialize the lens communication or not

This makes no difference, tried this many times.

Ok, some new news, i now also have shutter bug with the 22mm efm using the latest build that a1ex sent me. I installed TL with this lens on the camera this morning and got the shutter bug. Very strange.
Ive tried it a few times, its repeatable every time. Rotating the lens removes the bug. The bug doesnt appear if i use the efm adapter and an efs lens or M42 lens.

 I guess this shows the bug isnt related to IS or even the lens. Possibly more to do with lens activation. Does the running of the fir make any changes to lens FW as now neither my 22mm or 18-55mm will take shots with TL installed.

Log is here

Process.
Camera on. Run EOSM_202.fir (new from a1ex with no autoexec.bin). Check shutterbug is still occurring by trying to take a shot. After confirming bug is there I went into TL and enabled DM.log and quickly tried to take a shot but the bug prevents shutter. I then rotated lens on camera to eliminate the bug and took another shot, this time the shutter activated and quickly went into TL and stopped the log.

This log should therefore contain one shutter press with no activation, some kind of lens disconnect and reconnect and another shutter press with shutter activation.

Good luck.

Hi Malakai, since one can't shoot decent RAW with any of those cards it's hard (for me at least) to get worried about a bug I can't seem to replicate. You need to get a recent UHS 1 40MBS or greater card (like Sandisk).  Maybe borrow one?  Maybe it's complete wrong, but the two people with outstanding shutter bug problems are not using what I would consider the rights SD cards.  Shouldn't we factor that out?

I tried it yesterday with a brand new SanDisk SD Card, this one to be exact and it has the same bug.

I think you might find that the type of SD card has no effect on RAW capture. The sensor data will be exactly the same wether you use a cheap nasty card or a high priced top of the range card. All it will effect is the time it takes to write the data to the card.

As for the bug. I use my 18-55mm a lot and its a pain to use ML/TL with this bug. We shouldnt just factor this out just because you dont have it and a few of us do. I can see it not being an issue for those who dont use this lens or the 11-22mm. But there are some that do. Bearing in mind that ML/TL for the EOS M is still in alpha state. For it to ever progress out of alpha these bugs need ironing out.
