D700 buffer test -video-

rookieshooter

The D700 is rated to hold 100 JPEG files in its buffer, but I don't know what planet this measurement is based upon. Unhappy with the smallish number of files it could hold with a Sandisk Extreme III card I bought a UDMA card. Here are videos comparing both cards. I have wasted my money I think.

The UDMA card transfers a bit quicker but it's not enough to justify the cost IMO.

Let me know if you have experienced something different. I thought UDMA was the bomb but it doesn't seem much better than fast CF.

Disclaimer: I am using a USB reader, not firewire.

The camera buffer is what holds the files straight from the imager and image processer. The image files are then transfered from the camera buffer onto the flash memory card. The card transfer speed will not have a major impact on the number of images you can shoot in continuous mode, but it will have a minor impact in that the faster files can be cleared from the buffer, the faster you can add new images.

Double check your camera settings. I suspect that you are set to capture RAW files. The D700 buffer will hold 17 RAW files, so it seems more like what you are achieving.

The 100 JPG rating is probably images of nothing, a blank white background or black background for instance, and then optimal ISO since sensor noise is recorded as data and would result in larger file sizes, which occupy more buffer space. A "nothing" image should compress easily and to the smallest file size, resulting in the largest number of files in the buffer.

Also, you cannot learn much from manufacturer card ratings. Card transfer speeds are dependent upon many factors and are best judged empirically. Rob Galbraith has a very nice site that rates card speeds according to camera, card, JPG files and RAW files. The D700 tests are here:

Thanks Ziggy. The videos above are JPEG fine.

Check Custom Settings Menu: d:Shooting/Display, menu item 5, "Max continuous release".

Make sure it is set to 100.

Yep, set to 100.

FWIW I put it on manual focus, pointed it at a white wall and it took about 15 frames before slowing down. Same as before basically. This is with the UDMA 16GB card.

Maybe it's set to NEF+JPG? It sure sounds like a big files problem.

Keep looking for something like that. Stuff like this drives me crazy until I hit the "doh" moment of discovery.

The manual is located online at:

On page 423 you can find a listing of how many images the buffer will hold and under what circumstances.

I have never shot in RAW or NEF. This is it JPEG BASIC, low resolution:

Set it to "Basic" and try it again. "FINE" is the largest resolution JPG. Then, set it to RAW and leave it. That's too good a camera to be shooting stuff at the low-res setting!

I think "Fine" is a compression setting, that doesn't effect resolution. The least amount of compression would suggest fastest thruoghput.

The Fine setting on the Nikon camera is in reference to the resolution. Fine is high jpeg resolution. Set it to Basic.

Wrong. Fine, Normal, and Basic are the compression settings. Large, Medium, and Small are the resolutions.
