I might have missed it in the manual or Thom Hogan's book but I can't seem to find this one little tidbit of information.

When I want to check sharpness of an image I zoom in to view on the camera's LCD but I'm curious as to what the levels of magnification are.

From the full view thumbnail I can use the zoom button to go up 7 levels of magnification. What are they? It would seem that 5 or 6 levels is actually 100% and the last 1 or 2 levels is beyond 100%. Is that correct?

Can someone chime in with this information?

Six presses would be 100%. There are two beyond the sixth press so those would be over 100%. I've not compared the other levels of magnification to see what magnification they are though.

I have 8 clicks on mine.

This was posted on DPReview forums by Jerry Jongerius:

The monitor on the back of the D300 is a VGA resolution (640x480) LCD computer monitor. This means that are are 640x480x3 (921,600) dots comprising the monitor (each pixel is three RGB dots).

When you review photos on the back of the D300, each time you press the 'Playback Zoom In' button, you zoom in one "level". For purposes of the table below, zoom level zero is when you see your photo fill the entire width of the monitor, with two lines of text underneath it. Each time you press the 'Playback Zoom In' button, you go to the next level:

Level / Window Size / Zoom
0 / 4288 x 2848 / 16.85%
1 / 3413 x 2560 / 18.75%
2 / 2560 x 1920 / 25%
3 / 1920 x 1440 / 33%
4 / 1280 x 960 / 50%
5 / 960 x 720 / 66%
6 / 640 x 480 / 100%
7 / 320 x 240 / 200%
8 / 160 x 120 / 400%


As you zoom in/out and move around your photo, you will see the window size highlighted in a yellow box outline over a small iconic representation of your entire photo. Please note that the zoom percentage in the table above refers to the relationship between the 'window size' and the D300 monitor (and not a relationship between the photo size to the 'window size').

So, if you are reviewing a photo on the back of the D300 monitor at level 0 and you press the zoom button 4 times (now at level 4), you are now seeing a 1280x960 window into your photo. Since that window needs to be mapped onto the 640x480 monitor, the window pixels are reduced 50% in each direction (every 2x2 pixel block in your photo is mapped to one monitor pixel).

Press the zoom button two more times (now at level six), and you are seeing a 640x480 (or 100%) window into your photo (one pixel in your photo maps to one pixel on the monitor).

Press the zoom button two more times (now at level eight), and you are seeing a 400% blowup (every one pixel in your photo maps to a 4x4 pixel block on the monitor) of your photo.

This article applies to a large (4288x2848) photo sizes.

I'm confused. I'm sitting here right now with my D300 and I'm not going crazy.

From 0 (default thumbnail image) I can go 7 levels. There absolutely are not 8 levels above 0. There are 8 levels including 0.

So how do you explain this? I checked it a few times to make sure I had my info correct. either my D300 is different from all others or someone has the wrong information.

No matter what I do I only have 7 clicks from 0. Explanations?
Can someone else actually check their D300?

Here is an alternative that I am using:

In "Custom Setting Menu"
In "f Controls"
In "f1 Multi selector center button"
In "Playback Mode"
I choose "Zoom On/Off"
after the OK, I select "Medium Magnification"

That gives me a 100% view by pressing the center of the Multi selector button while reviewing a photo. One push to 100%, one push back to normal.

That's the same with mine. I wonder why yours is different, Robert. Which step does medium magnification give you? For mine, it's 6th step on medium, 4th step on low, and 8th step on high. By default thumbnail, you do mean the one with the file name, time, date, quality and resolution right? The step above default thumbnail has the yellow box showing and that is step one.

There are 8 clicks. The 6th is 100%

"Level / Window Size / Zoom
0 / 4288 x 2848 / 16.85%
1 / 3413 x 2560 / 18.75%
2 / 2560 x 1920 / 25%
3 / 1920 x 1440 / 33%
4 / 1280 x 960 / 50%
5 / 960 x 720 / 66%
6 / 640 x 480 / 100%

Hi Jonathan and others that chimed in on this one.

I figured it out.

Aparently, my camera had glitched at some point so that it would only zoom in 7 levels. When I changed the settings in f1 it corrected the glitch and Voila! 8 levels of magnification. I knew I was not losing my mind :biggrin:

I never knew about the zoom control in the f1 menu so I just played around and now it is working as it should and as others have suggested.

This is now how it works.

There are in fact 8 levels of magnification.
On the Low setting, pressing the center of the controller zooms up 4 levels. On the medium setting, it goes up 6 levels to 100%.
On the high setting, it zooms up 8 levels to 400%.

Now it makes sense and so do the previous responses to my question.

Thanks All.

Yeah you were, you had 8 clicks all along, you're just too embarrassed to admit it :biggrin:

Jonathan, for clarification, in my post the "100% view" is level 6 and "normal" view is level 0.
