No sinister plot. Just unjustified crippling of a fine product. The Canon way

Proof? You want proof that people aren't lying?

asking for further proof,different methodology isnt implying a lie...the Manual does say a slowdown in FPS may occur which implies NOT always occur
in certian lighting conditions..

Obviously many people don't care to read a thread before posting. I guess that is human nature.

Well, at least it's a lot better than the competition... Nikon claim 8 fps for the D300/D300s, but they actually top out at 2.5 fps.

p.8 #5 · 7D, 8FPS? only in good light!

I had really considered a 7D but the frame rate issue is a problem for me. I shoot in gyms where no flash is allowed at ISO 6400. F2.0, at 1/500s or less. I often have to push the exposure a stop in post but I need to keep the shutter speed up. It would seem the 7D will not give the 8fps I would like to have in the lighting I often have to shoot.

now how do you know that...this is as silly assertion that Canon screwed PRO photogs with the 1dmk3 A/F issues of which Canon did their best to fix
simpily an outragous belief

Mate, please, check the thread again. Read it. Read it well. The subject is 7D, not 1D3.

Hi Atsi,

Just got my 7D few days ago and while testing the 8fps in low light last night, I noticed this dropped bursts problem. I can easily duplicate the problem as described here although It only drops the speed in Ai Servo mode. Using Ai One shot in low light doesn't have this.

I was a bit surprised that nowhere in the web forums noticed this problem except here.

more likely it gives it a better shot to not just toss a mess of OOF frames at you

and certainly sports will usually be shot at better than ISO3200, f/2.8, 1/100th so it won't ever hurt there, 1/100th is FAR too slow

IF you guys post the settings you want me to set on my 7D, I'll make a video tonight! I guess I'll start shooting and place the lens cap back on and we can watch it drop to 4fps

digitalbug30d, you should visit a shop selling 7Ds, an try shooting with lens cap on. I think you'll be convinced.
why would I do that

It's easy. Lens cap on, M mode, 4fps.

I've only had it happen 1 time in real world use.

Metering was ISO 5000 f/2.8, 1/40

I just want to say that I read all 7 pages of this subject, and all I can say is, shame on Canon, 8 FPS means 8 FPS, not 8 FPS unless......, now Im thinking twice if I should even bother with this camera....
I really hope Canon is in the process of a firmware upgrade with a fix for this silly complication they have produced.

Tested this on mine...

C-Fn-II: 1-3, all disabled
C-Fn-III: AI Servo 1st/2nd image priority set to 2 (normally set to 0)
C-Fn-III: Lens drive when AF impossible set to 1

Manual 1/2000, f/1.8, ISO 100, lens cap on: 4-5 fps. Lens cap off, normal 8 fps.

Damn. This sucks.

Although, I did test it at 3200ISO, 1/100 and f2.8 and it was churning out 8fps no problem.

Lance, when I first read this, I was pissed, but in practice it's meaningless.

Think about this, when are you going to need the 8fps at that light level?

You have to read the white papers on the new autofocus design for the 7D/1D4.

You have to have enough light to utilize the minimum shutter speed for maximum high frame rate of the Digic 4 system. This operates the same way on the 1D3 (Digic 3) and 1D4. The frame rate will slow if you cannot obtain exposure at a high enough shutter speed.

For example and directly out of the 1D4 (same for 7D) white paper:

11-2 Continuous Shooting Speed:

- Maximum 10 frames per second
- For all image recording quality setting in both One-Shot AF and AI-Servo AF at
1/500 second and higher shutter speeds

Therefore on a 7D/1D4 if your exposure is below 1/500 the frame rate begins to drop off. This has been discussed here in FM and other forums. You only get the 8(7D) and 10 (1D4) frames per second is you have enough light for the minimum high frame rate shutter speed. Obviously and logically your not going to get maximum frame rate if the shutter speed is 1/60 of a second. Gosh people it's really logical, think about it.

Reading fail Dave! That is not the case! Go back and read the thread please. Even if you want black frames with no light in manual mode and set your shutter speed at 1/500s it will still drop down to 4fps. And no, all digic 3 and 4 cameras do not do it. 40D and 50D don't do it, nor does the 1D mkiii.

@droopy1592: +1

@davenfl: it's not so obvious and logical; all things set to manual (exposure, focus), at shutter speeds of 1/60s there should be no drop in frame rate; in an ideal scenario, at shutter speeds of 1/40s you could still reach 8fps (the math is based on a viewfinder blackout time of 100ms)
