Buffer size D7100
Aug 31, 2013

According to Nikon specs http://imaging.nikon.com/lineup/dslr/d7100/spec.htm the buffer size should be (L12, L14, C12, C14 for DX and 1,3 resp.)

7, 6, 9, 8 and 12, 8, 14, 11, but I can get only

7, 6, 8, 7 and 9, 7, 10, 8

with all buffer-eating features off (distortion corr, HI iso corr, Long iso corr)

What else is there to set to off?

I have RAW only, sorry, should've mentioned... I know that +JPG reduces buffer size, so I am trying all I can to get to the paper values, but there must be something hidden, or the web is lying.

Anyone any real experience with setting D7100?

It came up before (just recently) and the answer is an obvious one and now I can't find it. Same thing happens with the D7K. I'll keep trying.

Few other things.

Have you set the shutter to release not focus?

Are you shooting at at a slow shutter speed?

Are you spot metering or using matrix.

Is autoiso off?

Are you using a 90MB/sec SD card?

Check Auto-ISO off...that was the other one folks reported changed R number

Shutter release/ focus - if you mean settings A1 and A2, doesn't matter what I set, doesn't influence buffer size.

Slow shutter speed? Doesn't matter what shutter speed you set on the camera, the buffer still shows the numbers I've already written. Either 1/1000 s or 1 ", no change.

AF mode doesn't influence the buffer size.

I am not using Auto-iso. I've just checked, Auto-Iso up to 6400 doesn't influence buffer, only HI modes reduce buffer, quite dramatically to only 4 or even 3 frames in both DX and 1,3.

I am using 95 MB/s Sandisk UHS-1 Extreme Pro, but I can imagine how the card speed can influence the buffer

One firmware glitch I know of...
In reply to chary zp, Aug 31, 2013

In lossless 12 bit and 1.3x crop mode, the camera indicates that there are 9 shots in the buffer. There are 12, and I've confirmed it.

As I posted below, Auto-Iso doesn't influence buffer size up to native 6400, only HI modes influence buffer size, drop down to 3-4. Definitely not the drop from 14 to 10 (1,3x lossy 12bit)

Oh my, is it really that simple? Just an info bug?

You are right,

12 lossless 1,3 - 12 shots at 7 fps (says 9)

12 lossy 1,3 - 15 shots at 7 fps(says 10)

Not too bad for birds and hockey, after all

Thanks man for the right kick in the head. I've already written to Nikon, so I wonder what they come up with.

I shot with Nikon since the D100 and the buffer count on the top LCD is only an estimate of what you may get. You will almost always get more or less shots depending on the amount of detail in the scene you are shooting. Not a bug just the coder's of the machine best guess based "average" picture detail.

Notice the first disclaimer at the bottom of the chart. Shoot some pictures of a clear blue sky and you might be able to hit you numbers or do even better. Also every Nikon camera that I have ever owned starts writing to the memory card after the first shot so faster cards do make a difference in buffer performance.

That is of course true. But if the same principle applies to the camera and to the specs sheet, why do they differ in numbers? I'd be happy to read "10 frames buffer, depends on the scene" and find r10 on my camera display. No confusion. But why does the specs sheet say 14 when camera says 10? That's the point at this moment.

The "r" number is based on worse case and predictive. Normally it should match the chart. A setting seems to be giving you one less than what others owners show. All the normal culprits don't seem to be the cause.

You are right,

You got a 95MB/s card. Maybe the buffer empties before running out. Test your buffer with slower card...

Assumptions Mako...
In reply to Mako2011, Sep 1, 2013

My assumption is that with 12 bit lossless and 1.3 crop mode everyone sees 9 in the buffer rather than 12. If anyone sees 12 I'd like to hear it.
