Record mode display

Here you can see an example of the live preview image on the LCD (or EVF) just prior to taking a shot, note the wide focus bracket in the center of the frame. Various settings information is displayed around the edges of the display (detailed earlier in this review). Settings in this example: 2560 x 1920, FINE JPEG, Contrast -1, Exposure compensation +1.3, Sunny White balance, ISO 100, Programme exposure, Multi-segment metering, Single drive, 148 frames remaining.


Half-pressing the shutter release starts the cameras autofocus, once complete it locks along with metering system. In wide-AF mode (as above) the red rectangle indicates one of three positions (between the two black brackets, top image) which the AF system has automatically selected as the focus point. If the camera can't focus it will show a red dot. If the shot could suffer from blur due to hand shake (based on shutter speed and focal length) the hand icon is shown.

After fully depressing the shutter release a brief review (instant playback) is shown (this can be set to 2, 10 seconds or disabled). Press the QV/Delete button to cancel this image (do not save) or carry on shooting by quickly tapping the shutter release (half way).

RAW and TIFF formats do not allow you to return to shooting until the image have been written away, the EVF and LCD are blank during this process.


Pressing the Display information button (i+) removes all overlaid information for a 'clean display' preview. Pressing the Display information button again returns the AF brackets (or spot AF point) to the display.
Pressing the QV button gives a quick review playback of the last image shot, you can browse through images on the CF card by pressing the 4-way controller left or right. Once in QV mode pressing the 4-way controller up switches to this detailed exposure information and histogram. One bug-bear here is that you can't browse in this mode, you have to return to full screen display first.
An example of spot AF mode, you can move the cross-hair to any one of 285 possible locations (a 15 x 19 grid). Once the cross-hair is in the required position a half-press of the shutter release will trigger AF, or if you have AF set to continuous it will focus automatically. Example of the center metering circle displayed when metering is switched to spot.
 
After shooting in continuous drive mode all of the images in the sequence are shown as thumbnails, at this stage you can choose to delete before they are written away or continue shooting.  

It would have been nice to see the option to have a histogram display for the record review image, as it is it's a little slow to press QV then the up arrow to display the histogram.


Manual focus

Pressing the AF/MF button switches the camera to manual focus. This is indicated on-screen by the MF icon and the focus distance readout directly below (0.56m in this case). Rotate the focus-by-wire ring at the back of the lens to adjust focus. Minimum focus distance is 0.50m in normal focus range, 0.25m with the lens engaged into macro focus range. The D7 features an very useful magnification mode which provides a 4x magnified view of the center of the frame which enables you to confirm the accuracy of the focus point.
 
During testing I found a bug (probably just in this firmware - Japan shipping version) which turned the magnified screen almost black when any exposure compensation is set.  


Play display

Switching to play mode immediately displays the last image taken. The D7 must use a low resolution 'thumbnail' image in the file header because it displays images very quickly. Press the 4-way controller left or right to browse through images. Pushing the 4-way controller up displays a histogram of the image along with detailed exposure information.
Pressing the QV/delete button in play mode displays this delete confirmation prompt. Pressing the magnify button magnifies the image in three steps: x2.0, x2.5, x4.0. Once magnified you can pan around the image using the 4-way controller.
Pressing the Display information button (i+) twice switches to a thumbnail display which can be configured to either 4 (2x2) or 9 (3x3) images. A similar thumbnail view is also used to mark images for protection / deletion / print order.
