I have recently received my D7500 (upgrading from an original D70!) and I am perplexed by one icon on the rear screen that I can't seem to locate information about.

It is at the left side at the top of the rear screen (above the line) and looks like a small, white rectangle with a black oval interior and the letter N next to it. I haven't been able to find it in the manual, but here is an out of focus picture (taken with my beloved Canon G15)

On the same level, and to the right of this icon is the Hand icon that indicates VR being switched on for the attached lens. This makes me think that it may be a lens related icon, but as all of my other lenses are genuine Nikon, I get the same icon no matter what lens is connected.

Can anyone enlighten me as to what this N icon means?

  • A picture is worth almost all of the words in your question. =) Can you upload a picture of the icon you're describing? – scottbb Jun 18 '17 at 17:53
  • @scottbb Make me get out my second camera why don't you! But see the image. – Peter M Jun 18 '17 at 18:05

What you are describing is the Vignette Control Indicator.

From page 203 of the D7500 User Manual, the area pointed to by "27":

From page 255 of the manual,

Vignette control (defaults to Normal)

High, Normal, Low, Off

Reduces the drop in brightness at the edges of photographs when using type G, E, and D lenses (PC lenses excluded). The effect is most noticeable at maximum aperture.

  • I have been through that damn manual twice already and with my camera in hand but I obviously missed it. And at 356 pages of small print, it is no light read. – Peter M Jun 18 '17 at 18:09

    What? You don't find it engaging and page-turning? – scottbb Jun 18 '17 at 18:10
  • Given the step up from my D70 I find it somewhat overwhelming! On the other hand this camera does have a tad more features. – Peter M Jun 18 '17 at 18:11

    You questions both inform and worry me! Anyway I just took 2 photos in RAW of the same blank wall. One with Vignette Control turned off and one with it on Full. Looking at the histogram on the back of the camera I can see a visible shift to the right for the full vignette control image. However I am not 100% sure if the histogram is of the RAW image or of the JPG construct displayed on the LCD. – Peter M Jun 19 '17 at 19:31

    Just opened both RAW images in Affinity Photo and I can see histogram differences there. So it look like it is a RAW modification. That plus me having access to the menu item when the camera is configured to shoot RAW only. Also the Picture Control menu items are also available in RAW mode and I had the understanding that they affected the RAW file – Peter M Jun 19 '17 at 19:39
