Canon EOS 60D takes up to 30 seconds to load Dual-ISO module after wakup.

[BobbyBonsaimind]

I've got a Canon EOS 60D with Magic Lantern (Nightly.2018May01.60D111) and I've found myself using Dual-ISO a lot lately. However, *sometimes* the camera takes "normal" pictures without Dual-ISO even though it is enabled in the ML settings. I could not pinpoint when exactly that happens, but it seems to me like the module isn't loaded "fast enough" when the camera wakes up from standby. Though, that is only a hunch, sometimes it seems that if flings out after taking some pictures.

Has somebody seen something like that before? Or is there an automatic which disables Dual-ISO in certain conditions which I'm not aware of?

General recommendation: Use lua_fix build instead of nightly.
It is almost guaranteed nobody will look into nighty bulld issues now and in the future.

Try to reproduce your issue and come back if problem occurs again.

Oh, wasn't aware that that exists. Thank you, will give it a try.

I'm now using the latest lua_fix version, and the problem is there, too.

It seems like that the modules (all of them) are not loaded for up to 30 seconds after the camera wakes up.

• Camera is switched on.
• Dual-ISO is enabled
• Not having taken a photo for several minutes, camera has gone to sleep.
• Pressing the shutter button, camera wakes up, takes picture without Dual-ISO.
• ~10-30 seconds later the Dual-ISO module gets loaded and pictures are taken with Dual-ISO again.

When I wake the camera up and go into the Magic Lantern menu, the options for the modules do not appear there. The modules are visible as enabled in the module-list menu, though. If I wait in the Magic Lantern menu, the module options will pop-in when the module gets loaded "later".

Any ideas?

Works fine on 70D.  I can't think of many reasons why you'd see this behaviour, one possible is if you have multiple modules enabled and one is slow to initialise.

Do you see the problem if you:
- disable all modules
- enable only dual_iso
- restart cam
- wait for cam to sleep and test as before

Assuming that works okay, enable other modules *one at a time*, and re-test each time.  This should let you find which other module is causing the problem.

[BobbyBonsaimind]

Yes, I'm seeing that delay even with all other modules disabled, too.

The time until the module becomes available seems to vary, though, might be related to how "busy" the camera is with taking and storing photos, bu that is a wild guess of mine. Haven't had that much time to do thorough tests.

[Walter Schulz]

This is far from normal.

How it should work: As soon as Magic Lantern is loaded completely and ML menu system is accessible all modules should be up and running. A delayed start (by up to 30 seconds) is unheard until now.

Have you tried another card as well? Preferable something in Class 10?

[BobbyBonsaimind]

No I haven't, and the current card is a Class 10. But I already had thought that it might be related to the card, however, so far it hasn't given me any other troubles (no writing errors, no corrupted images, no read errors, no speed reduction that I would have noticed...).

I will test the card and then the behavior with another one. Thanks all for the comments so far.

Sounds strange.  How could it be busy with taking or storing photos, if it was asleep?  Are you doing something unusual before or after it goes to sleep?

Because I'm waking it up with the shutter button and I'm taking images, but those images that are being taken are without the Dual-ISO module being loaded. The module only gets loaded later. How much later seems to vary, which might or might not be related to how busy the camera and card is.

[names_are_hard]

Okay, so it's not busy before it sleeps, or during.

I tested 70D waking from sleep by holding full shutter until it took a pic, then immediately entering ML menu.  Dual ISO menu options were present.  Didn't time it, but less than 2s.
