Nikon D7100 - MP choice?

[Chri5]

I was under the impression that my D7100 was set to 24 mp but when I was playing around with an image in Viveza it said I was set at 13 mp. How do I check/adjust my mp on the D7100? It might already be set a 24 and it could be that Viveza got it wrong but just in case. Thanks in advance.

It may be that your camera is set on 1.3 crop mode. If there is a black frame showing in the viewfinder that would indicate it is. You can go into the menu, to shooting menu, I think, and go through the menu options till you find one that says "shooting area" or something like that, then go into that menu and set it to DX mode, instead of 1.3 crop mode. Does that help?

If you are sure your camera is on dx mode, you could try taking another shot and putting it in the program to see what it does.
There must be an error somewhere.

You can simply check image dimensions in Windows file properties. If it is 6000 x 4000 pixels, that's 24Mp

Hi Chri5,

ye may have changed the image size without noticing... e.g. my Sony is L=12mp, M=6.3mp. Ah'd imagine ye have similar in the d7100.

Hi Chris,

Which do you mean?

MP (Mega Pixels) = image dimensional area
or
MB (Mega Bytes) = filesize

On the D7100, there are two settings that will affect image dimension area (MP) - as mentioned by others:

DX mode = "24 x 18" = 24 MP = 6000 x 4000 pixels
(typical 14 bit, lossless compressed, RAW file size = approx. 34 MB)
1.3X mode = "18 x 12" = 15 MP = 4800 x 3200 pixels
(typical 14 bit, lossless compressed, RAW file size = approx. 20 MB)

It really doesn't help that Nikon interchangeably use either: "18 x 12" and "24 x 18" in some areas of the menus, displays and manuals and "1.3X" or "DX" in other places, to describe the same setting.

That said, I love the 1.3X mode and very often use it for distant wildlife.

My Nikon D7100 manual's index says the topic is mentioned on pages 58, 63, 68 and 167.


There are many things that will affect the file sizes (MB);

RAW or JPG
JPG quality setting (Fine, Medium, Standard)
RAW compression settings (uncompressed, lossless compressed, lossy compressed)
RAW bit depth (12 or 14)

Using Nikon's ViewNX software will allow full disclosure of even a RAW file's settings for all the above.

Can't say what Vivenza makes of it as I don't have it.
Also, file size as reported in an editing programme can vastly differ from what the camera shot depending what image format it thinks you're going to save in.

HTH, Dave

Are you checking raw or JPEG? I guess you are looking at JPEG file. Make sure that JPEG file quality is set to high (I guess fine) as per the camera standards. Medium and low will have smaller files for higher burst rate.

Sound like its set to (M) medium and not large - from Nikon's site:

Image size (pixels)

DX (24x16) image area: 6000 x 4000 [L], 4496 x 3000 [M], 2992 x 2000 [S]

1.3x (18x12) image area: 4800 x 3200 [L], 3600 x 2400 [M], 2400 x 1600 [S]

4496 x 3000 [M] = 13488000

Here is a link to a guide as to where all the commands are.

Why not use CUSTOM Menu and save your most used settings.

Hi Chris,

Enter your shooting menu and scroll down until you find image quality. There is a selection of raw, raw plus jpeg fine for the largest size... If you shoot raw and jpeg, you may then scroll down one more level in the same menu to select image size and choose your preferred size/quality for your jpeg files.

Or just press the button marked QUAL and turn the sub dial - the one on the front.

L (24mp)
M (13mp)
S (6mp)
