p.11 #17D, 8FPS? only in good light!
Try locking exposure (e.g., hold down * button) while machine-gunning in Tv. I don't have my camera with me at the moment, but I'm pretty sure this is how I got the 7D to shoot 8fps (or thereabouts) for low light shooting.
Of course, I would prefer that Canon do it right, and allow 8 fps in full-manual (w/manual ISO selection).

I can not achieve any where near 8 fps in any thing other than bright light in any mode. The other thing I can't do is get my 7D to AF track the way Canon states that it will in all of their 7D promo videos on the Canon web site or at B+H. There's an awful lot I like about the 7D but there are a few things (IMO) that Canon stretched the truth on a bit. Any one can opine all they wan't...Show more →

Paulfeng, Yes that works! Thanks for the tip!

Excellent! And your avatar inspired me to change mine... Bragging rights to the first person to correctly identify my alter-ego.
P.S. I think I got the tip from someone else's post earlier in this thread... just reboosting it.

Everyone who is concerned about this problem should call, write, or email Canon about it and bug them every few weeks until we get an answer. I have already made a number of calls but obviously one person complaining gets us no where.

no changes with any of the firmware updates. I guess that Canon doesn't care to fix things that are easy to fix.

I would call Canon to confirn this is a feature, not a malfunction.
Canon phone support is pretty good and fast to answer the phone and available almsot 24/7.
locking exposure is a good idea to try too.

Locking exposure DOES stop this unwanted behavior in other modes, but one cannot lock exposure in manual mode.
I have called Canon, and when I did they didn't know of the issue or pretended to not know. The fix is simple, turn off the exposure system when the camera is in manual mode and the shutter button is depressed. It is possible because with exposure locked in other modes it fires full 8FPS.
And I will say it again. This did not occur with the 300D, the 20D, 30D, 40D nor the 50D. This is a small step backwards on a superior model.

You can modify the shutter button to not do exposure.
that will turn it off in manual.

No you can't.\, you can have it do an exposure Meter Start/AF, Meter Start only, or Exposure Lock. None of these settings affect the problem.

Someone else said some of this already but I'll say I found more on it too:
---------
On page 93 in the manual there is a note:
*In the AI Servo AF mode, the continuous shooting speed may become slightly slower depending on the subject and the lens used.
*In low-light areas or indoors, the continuous shooting speed may become slower even if a fast shutter speed is set.
----------
In the Troubleshooting Guide Section of the Manual - On page 245
Max burst during continuous shooting is slower:
*If you shoot a subject which has fine detail (field of grass, etc.) the file size will be larger and
the actual maximum burst will be lower than the number mentioned in the tables on page 59.
*High ISO speed noise reduction setting can cause this C.Fn II -2 [Standard/Low/Disable].
If set to [Strong], the max burst during continuous shooting will decrease. (page.208)
*When I use AV mode with flash, the shutter speed becomes slow.
-if you shoot at night when the background is dark, the shutter speed becomes slow automatically (slow-sync shooting) so that
both the subject and background are properly exposed.
If you do not want slow shutter speeds to be set,
then set C.Fn I-7: Flash sync. speed in AV mode to 1 or 2 (page 207)
----------
So, I wonder if the auto assist beam might help compensate and keep speeds up.
Can you test that and also the other custom function settings I mentioned?
Also, check out the -Function Availability Table- on page 237.
That table shows AE lock won’t work in Manual, but it works in P mode.
So, just configure P the way you would on Manual mode,
then test out the low light continuous shooting rate while holding AE lock!

But the point is that the problem is in MANUAL mode and that is what needs to be fixed. I know I can shoot in other modes with the AE locked, which is also proof that the bug is solely a software problem that could be corrected very easily.
I understand fully the other functions, in fact all of the functions of the camera. The problem is a simple one and Canon ignores the simple fix for some reason.

it is not a bug, it is by design.
Canon alwasy find a way to limit the non 1D cameras in some way like this.
That way they dont compete with the 1D's sales too much.
The Rebel XT only has 2 metering modes, but has all the same guts as the XSi, for example.

Let me repeat, the 300D, 20D, 30D, 40D, and 50D all do not have this problem. It is not by design IMHO but a overlooked bug. There is absolutely no reason the slow down the camera in low light conditions in Manual mode, there is nothing to meter. The metering is what is holding things back. Anyway, this is getting circular. I appreciate your interaction on the subject, but it is a problem for me, and for some others. If it is not a problem for other people that is fine but that should not negate the existence of the problem.

Let me repeat, why would there be a reason to buy a 1D if the 7D was perfect?
Marketing rules Canon's reason, and always has.

It is by design in both the 7D and 1D4. Read the white papers.

The canon 1D IV manual says you can use AE lock in Manual mode, but not in movie mode.
Also the 1D IV does not lower the FPS when in low light, as the 7D manual states it does do.

I also read the manual slowly, and the other whitepapers, there is a chart that is mis-undeerstood, that says it is not available normaly,
but then you read on that it is available via custom menu setting to turn AE lock on while in Manual mose as well as
during auto exposure video shooting, exposure compensation and AE lock are available.
The 1D IV is not limited in the same ways the 7D was discussed in this thread.
Quote:
9-8 AE lock:
(1) Auto AE lock
• In the One-Shot AF mode with evaluative metering, AE lock takes effect when
focus is achieved.
(2) Manual AE lock
• In the M, P, Tv and Av modes, enabled with the AE lock button (press again to update).
• Enabled in all metering modes.
14-16 AE lock:
• During movie shooting, press AEL button for AE lock or the AF point selection
button to cancel AE lock (no automatic cancellation).
• With AE lock set before movie shooting, movie shooting can start.

I must regress a moment - wait up -
Isn't AEL (Auto Exposure Lock) only useful in the program modes, in Manual mode what would it even do?
In manual mode the EC is still active for + - adjsutments, but there is no Auto exposing durring manual mode.
The exposure is set by the user in manual mode.
The OP only pointed out that he wanted to use it to possibly compensate for the 7D delaying shutter release in dark lighting conditions.
The 1D IV has no delay, when it is dark it keeps 10FPS going.
The 7D does not, but AE Lock isnt the issue at all, not is it possibly active in Manual mode.
