Or maybe it doesn't do 1/24. Since you can choose an aperture larger or smaller then the lens is capable of, it might not do as you tell it all the time. Even though my lens is f/2.8, it only changes the aperture two button presses after f/3.2,

So I is it possible to get more that 1/24 with the hardware on the T1i? I realize it would be at the cost of things appearing blurry but in low light and for certain projects (shots of water flowing) it would be quite helpful. Lens also has no bearing on shutter speed also as that is done in the camera body correct? and likewise shutter speed also shouldn't have any bearing on the depth of field as DOF is contingent on focal length correct?

I'm not an expert in filming, so I don't know if it's possible to have a longer shutterspeed than the amount of frames per second. Other canon cameras don't do that, at least.
After a quick test, I can't notice any brightness difference between 1/24 and 1/31. But something is happening, since I get some flickering when choosing under 1/31th second. The flicker is something like fluorescent bulbs, even without being close to fluorescent light.

Update: This is wrong, no flickering with shutter speeds lower tan 1/31 second :/ it might have been a fluorescent bulb...

You're right that the electronic shutter is lens independent, and depth of field is contingent upon focal length and aperture.  I don't know what the lower limit of shutter is for the 500d, but 24 gets pretty choppy as is.

With the manual aperture I can't seem to get it lower than 5.6, it never cycles back around.  Thoughts?  Am I missing something?

Everything I'm reading is saying shutter speed slower than frame rate is not possible.  So unlocking FPS is really what one would have to do to get longer than 1/30th of sec. shutter speed

Ok, sweet.  Got ML to drop my aperture, always good to read the manual (duh).  I can't seem to get ML to remember my manual exposure settings, or the auto exposure override.  Is this just not yet implemented?

Mine doesn't remember exposure settings eather, normally it's at 1/120 an f/5.6 when boot up, but every once in a while it remembers it :) like in this writing moment. Now I started in M, and switched over to a-dep(remapped to movie mode). It remembered shutter speed and aperture, but it's always ISO 400 while doing this.

Yeah, mine defaults to 400/120/5.6 also.  Even if I do a config save, ML defaults to these settings.

And I echo previous comments that all apertures showing.  I wish my Sigma 1.4 went lower, but it just stops stopping at 1.4  :D Correction: the aperture actually stops stopping at 1.6, it seems that the numbers are a tad off. 

I'm loving this new feature though, Alex.  Thanks so much for your efforts.  I'm not trying to complain, just beta test.  You know if you gave us a bag of gold we'd complaint that it was too heavy.

Didn't see any settings for it in magic.cfg after saving so I assume nothing gets logged.
