I'm trying to get my D300s to fire more than 15 shots before it slows down but I'm not geting a great deal of luck. I'm using an Extreme 16GB 60MB/s card so that should not be the issue can you guys tell me what I may have done to the camera?

PS it's te same in JPEG and RAW
 
I think the buffer can only hold 15 RAW shots on the D300 and D700. Even with a 600X card it doesn't change much, just allows the camera to empty the buffer to CF quicker.

The limiting factor are the RAW file sizes and the size of the buffer. 12.1 mp shots are rougly 15meg each in NEF, so it looks like the camera has 256MB of internal buffer. If you shoot in JPEG only you will get far more shots before it starts slowing down as the file sizes are smaller, so the buffer takes longer to fill up.

Have a really fast card may help you get one or possibly two more shot but I don't think you can expect much more than that unfortunately.

It's the same in RAW and JPEG no matter what the size that's why I think it's odd.

Have you set it for 12-bit or 14-bit raw files?

12bit for the test

you can set it to a limit the shots,
page 282 of manual.d5 in the menu.
hope this helps

That only work on the CL setting...

lost me if you want to shot as many shots as poss it has to be in ch mode and d5 in the menu set to 100. then you should be able to shot 100 shots if the card is fast enought to clear the buffer, if not it should manage fine large jpegs 43 shots before buffer fills.
and 12bit raw uncompressed 17 shots. and large tiffs 16 shots same as 14bit raw.
 
The other way to keep you buffer working the best it can is to only allow the camera to take a pic when in focus. Stops it getting clogged up with OOF shots. There is a custom setting to only record in focus images somewhere.

well a fault with the crd maybe, where did you get it.

Jessops and with full cover, but I guess I need to establish if the error is with me first. The 7D shoots pretty much until the card runs out so the 300s should do the same and for a while it did. I had to reset the shooting functions after I let someone else use the camera and he decided to be "creative" with the settings.
 
Turn off Active-D lighting, shoot jpgs and it will shoot in continuous high for a stupid number of shots, possibly forever. You need a fast CF card though - I used Ultra III's.

With Active-D turned on, you will get about a dozen on so (maybe a few more on the 300S). Its because Active-D is processing the image and so it needs to be held, processed then written to the card, so the buffer fills up. Turn it off and all it has to do is jpeg compress and write to the card.

Definitive answer!......You beat me to it:thumbs:
 
when looking through your view finder and half pressing the shutter, you should get a number next to your iso setting in brackets. this is the number of shots your buffer can hold. hth mike if you change your settings and refer back to this you,ll know if you,ve changed it correctly.

this is very interesting, i am using sandisk 30mb and its coming up at r21

I can not believe I did not know that... :cuckoo:

Ok the main route of my problem was the ISO noise reduction how i missed that I have no idea.

With a 60mb/s SD Extreme card the following speeds can be achieved by the buffer according to the buffer guide with all the crap turned off (big nod to Mike :clap: )

RAW 12 bit r17

TIFF L r14
JPEG L Fine r21
JPEG L Norm r28
JPEG L Basic r45

TIFF M r17
JPEG M Fine r28
JPEG M Norm r45
JPEG M Basic r46

TIFF S r23
JPEG S Fine r45
JPEG S Norm r46
JPEG S Basic r46

I hope this helps someone as much as you guys have helped me. I may even collate this all together and try and get a sticky post for reference. Perhaps with different cards and the actual shot vs the number on the "r" number?

Chris.
