I personally am not swayed by the joke.  ML is still the best option to expand a supported stock camera.  I always keep a backup non-ML camera just because as another reader pointed out, s___ happens.  Fortunately I've never had a situation where ML has failed to deliver what I completely intended.  I currently use it on a 5diii and an M.  I have used it on a 60d for time lapse and had no issues.

I still will use it on my 5d3 as the single most useful feature for me is dual ISO. It has saved the day on a number of wildlife excursions and sports events where lighting was not optimal.  I believe those that are trashing it before trying it, likely would never use it regardless.

I have full trust  in using it and I'm sure after this that Alex won't do that stunt again.

Just timed the bootup on 5D3-ML.

From power off, flip the power switch and half-press shutter. ~2.5 seconds until anything active on viewfinder (af starts).

From sleep,half-press shutter. ~2.5 seconds to AF start.

Wasn't non-ML something like 0.2 seconds on those?

Ugh, that's strange - maybe a problem with the Canon fw trying to load ML from either cf or sd. My 6d is *way* faster with ML installed, 2.5s is really tiresome. I suggest to ask on the ML forum if there's trick to speed this up on 5d3: http://www.magiclantern.fm/forum/index.php?topic=11017.0

Out of interest:  Does this time change...
* when you're using an empty card (i.e. not pictures)?
* with how many modules you load?

I looked onto this a while back and it has to do with the way ML attaches itself into memory.  In order to use ML, the camera has to use the boot from card setting which is "reserved" for canon bench testing.  Speed was not a priority at Canon for such testing modes.  Pulling the memory card does not "fix" it.  You must do a firmware uninstall to remove the boot flag.  The issue is with the Canon firmware and not ML (proven by removing the ML card and software leaving only the boot flag setting and still having the delay).
 
A workaround that I use is to lengthen the sleep timeout to a sufficiently large number.  Uses more battery (slightly) and it's a trade off.  In fact the boot and wake delay is the ONLY trade off with using it in the 5DIII. 

I deal with the power on delay and have mitigated the sleep delay by increasing the sleep timeout.

I don't think anyone is trashing it, or at least I'm not.  I have a lot of respect for Alex and everyone else who has worked hard to improve the firmware of Canon DSLRs.  ML has really pushed the capabilities and I believe that Canon's support (in terms of not voiding warranties) shows that they respect the work and the caution that goes into making sure it doesn't blow up cameras.

On the other hand, I think it depends on the work you do and whether the trade offs are or aren't a big deal to you.

Yes, I think East Wind is correct about the boot time, that's my understanding too. Nothing really can be done there I guess, without reflashing the whole camera into ML.

One feature I wish they could add is more flexible frame rate for video. I think I was able to go ~70fps at best, but I'd love option to lower resolution while increasing fps, e.g. 720p240 or such.

Then there's this - not a good thing if you intend to use your DSLR for paid work.  Marsu et al, sorry, but this one is going to hurt their reputation

I know, I saw the general idea it in the source commits and of course disabled it on my personal build, I didn't even look what it did exactly. Imho there's good and bad about it. The bad obviously is that people lost shots, but the good news is that there's no way 'round making clear what ML is or isn't ... basically I agree with http://www.magiclantern.fm/forum/index.php?topic=14779.msg143039#msg143039

* as for ML's target audience: "They" cannot cope with expectations anyway, because "they" is "he" and as it's developed by a single person with some expert help on video and some less expert help on specific cameras. I would never recommend running ML for critical pro work like a wedding (and I've never written as such), even though I find it rock stable. If you want pro, buy pro. This is an amateur project to un-cripple the budget to mid-range Canon cameras, they don't even accept donations.

* As for "sorry for me": That's just it, I'm sorry for everyone not using ML because it has features that really make a difference (dual_iso, raw histogram, un-broken auto iso, the lot). It's not like I gain anything from promoting it, actually that's the very reason I stopped contributing source code as it's more hassle than fun.

I just hope the bad rep won't drive ML into stubbornness as so many oss projects who adopt a "take it or leave it" stance and are too quick to say "if you don't contribute (source or bug reports), you have no say in this". But the main dev is a really nice guy, he's doing it for personal fun, and ML's site is very clear on what to expect or not.

Marsu, as I said a few posts above, I have nothing but respect for Alex and what he and the rest of the community are doing.  I mean no disrespect to you, ML or anyone else, and I like April Fool's jokes, but I thought that going a bit too far.  That's just my opinion.

Hi Folks.
It seems pretty dumb to do the April Fools Joke, yes we all know ML is free, excellent, and NOT for mission critical work! But when is it not mission critical, ok we'll discount weddings and other professional uses, but what about shooting the relatives 81st birthday, ok they may not be here for the 82nd so I can't use it for that, Jimmy's 10th, that should be ok but he might step in front of a bus larking about on the way home from school, better not use it for that, oh well that landscape but what if the sun and clouds never look like Jesus again, ok when can I use it without worrying that some other joke will cause me to miss a shot?

Cheers, Graham.

I didn't think you meant any disrespect to anyone! And, as the fact shows that he took the joke back asap, shows that he himself had doubts.

I just wrote the above yadayada because I'd think such occurrences are quickly taken out of context and people might confuse ML with a commercial software - often posts appear as if ML would be desperately try to sell their "hack" to a reluctant Canon crowd and they'd have the convince the users of its worth... but it's the other way 'round.

That's probably true as ML has come so far and does so much.
