Will this card help the D7100 Buffer issue?

More than enough. I shoot using 90mb/s cards with no issue. So I am of the opinion anything faster than that exceeds what the camera is capable of.

The only help a fast card can be is to empty the buffer a bit quicker,i have a 95mb/s card and i can get quiet a long run on CL but it will not cure the problem.

You also have to think about the limitations of the camera it's self.

The brains of the camera can only work at a certain speed, saving continuous shots until it can't read and write fast enough,

yes, A faster card might help a little, but not that much.

Do you mean the physical limitation in how the camera was designed to work, or an 'issue'?

I took the OP to mean the small buffer size,in which case all you can do is have a card that will take the info as fast as the camera can send it,so a fast card may/will help.

If that's the case, one may be using the wrong card which cannot keep up with the camera. I'm not viewing that as a 'D7100 Buffer Issue' :)

I am speaking of an issue... I often shoot sports with my D7100. If it is set to CL or CH I usually get 8-12 shots before the "buffer" kicks in. This is with a 95mb/s card.

My thoughts are you will not improve on this,the D7100 does have a small buffer,its only weak point.

I belive the camera is working as designed. I encounter the same when shooting youth sports, I understood the limits when I bought the camera.

Sounds like you bought a Chevy Cruze and want to drive 200 MPH :)

Carguy, the D7100 has a small buffer. You can call it what you want but i call that an issue.
Maybe semantics, maybe not.

When a product works as advertised and designed, it is not an issue. An issue is when a product does NOT work as intended.
Nikon makes cameras with larger buffers, if that is what you need maybe you bought the wrong one?

Just my $.02 :)

I don't see that as an issue, as that is what the manufacturer intended to not compete with its more expensive models. I see it more as a misinformed customer assuming the buffer can magically change because its owner wants it to.
Need a larger buffer?
Shoot in jpg small.

Sorry Skene, I am far from misinformed. I knew about the buffer size when I purchased the camera. I simply found a faster SD card and was wondering would it decrease the lag. That is all.

Once again. There is no issue with the camera itself. The buffer size is not an issue. It is working the way it is supposed to work.

For arguments sake lets just call this "User Error", cause you are trying to address the factory set buffer as an issue. Which it is not, and no SD card in the world would fix that. SD cards do not automatically increase buffer size to allow you to take smaller pictures.
Once again if you need space in your buffer... Change your save file type and size.

Typically, 'card speed' is based on how fast the card can be read, not write. Yes, the faster it reads usually translates to a faster write speed. But the two are not interchangeable.

As I stated, I use 95mb/s cards. I tried a 45mb/s card and it slowed down just a bit, but not much. An 80mb/s card isn't any faster. So I'd say a 95mb/s card is either as fast as the camera can handle or is faster. A faster card won't speed the camera up any.

Looking at the specs of the D7100, it isn't capable of writing quicker than 95-100 mb/sec, so anything more than that is, at least on paper, wasted - However, if you look at the various test sites out there the camera doesn't hit the full capacity of the card. I believe the 95 MB/Sec SanDisks allow the D7100 to write to them at ~75MB/sec so faster card may go nearer 95 MB/Sec.... Then again, that is only 3/4 of a RAW file per second.

There was a thread not so long ago on this with reference sites with test data, I'll look it up for you to check out.

How exactly do you define, "small buffer"?

Does the buffer, in fact, buffer?

Yes it does.

Then the only "issue" is your opinion on the size of the buffer which is entirely different than there being an issue with the buffer itself.
