Does shooting in Raw+ Jpeg low down the buffer more than shooting just RAW?

There's no need to shoot RAW+JPEG in camera, nor to batch convert in DPP. IJFR is so easy and fast to use. HERE'S THE LINK. Give it a try. you'll be glad that you did.

That does depend on the model. If you have older cameras, this really wouldn't be an option because in the past, the JPG in the raw was a smaller sized "thumbnail". It was perhaps the 7D/1D4 era where this changed so that a full sized JPG is contained inside the raw payload.

Yes, that's a good point. Good reason to buy a new camera too.

I guess the thread title says it all: Does shooting in Raw+ Jpeg low down the buffer more than shooting just RAW?

I never shoot Jpeg alone. I kind of wish I could (because the buffer rate is far less of an issue), but I'm not that brave. So I usually shoot RAW + Jpeg. That slows things down a bit, obviously.

Will shooting in only RAW be faster than shooting RAW + Jpeg or does it not matter?

Thanks

I just put my 6D through the buffer-drill. I use a Sandisk Extreme class 10 45mb/s card. Settings: iso 100, f/2, 1/4000. Listed number is shots at full speed; I stop counting when the buffer slows down the frame rate.

Raw: 23 frames (owner's manual says 17)
Raw+JPG (large/fine): 9 (manual says 8)
JPG (large/fine): I stopped at 50, seems unlimited (manual says unlimited)

In each case the buffer was clear by the time I could look for a red light. I usually use JPG (l/f) for action stuff. I had no idea the 6D could go 23 frames deep and be ready to shoot again in a second or two.

EDIT: Added data from user manual. I guess I can use my 6D for action stuff! I always default to the 60D for that.

For what it is worth a simple comparison with two other camera's.
I haven't shot and counted as GeoKras did but just looked at the camera info.

7D Raw -> 22 frames burst buffer according to the camera.
7D Raw+L -> 17 frames
7D Raw+M -> 18 frames
7D Raw+S -> 18 frames

50D Raw -> 15 frames
50D Raw+L -> 10 frames
50D Raw+M -> 10 frames
50D Raw+S -> 10 frames

While I do really like IJFR it does have one problem, the embedded jpegs are highly compressed, although still of fair quality.

Here's the file sizes of some image versions (all the same image)...

original raw - 31.3 MB
original jpeg - 8.0 MB
DPP jpeg - 10.4 MB
IJFR jpeg - 2.9 MB
FastStone jpeg - 3.2 MB

FastStone also extracts the embedded jpeg.

Hmmm, I wasn't aware of that. At a glance they seem to be very good copies, but perhaps I should do some comparisons. Thanks Frank.

I'm curious what the Large/Fine jpg buffer is on the 7D. I'm guessing until the card is full.

When shooting jpegs the 7D will write to the card and shoot simultaneously, so it depends a lot on how fast your card is.
If you shoot RAW+jpeg, it will not store images and shoot at the same time, thus card speed is only important for the time to recover from buffer full, not for how long you can shoot until the buffer is full.
