Nikon D60 Viewfinder & LCD
Nikon D60 Viewfinder
Nikon says D60's viewfinder provides a magnification of 0.8x and a coverage of about 95% (coverage was actually a little higher than that in our tests). The D60's dioptric correction adjustment (for eyeglass wearers) has a range from -1.7 to +0.5 diopter. Some of us had a hard time reaching the dioptric adjustment, a slider on the right side of the viewfinder eyepiece housing. Those of us with fingernails on our thumbs found that they worked quite well as dioptric actuators though. :-) The viewfinder has an eyepoint height of 18mm at -1 diopter. This is enough that most eyeglass wearers should be able to see the full viewfinder area without having to mash their glasses against the viewfinder bezel. The D60's viewfinder is a pentamirror design, rather than the more costly, but brighter pentaprism.
The viewfinder is actually one of the bigger distinguishing features between the D60 and D80: The D80 uses a pentaprism design, has a magnification factor of 0.94x, a higher eyepoint of 19.5mm, and a diopter adjustment range of -2.0 to +1.0. While the D60's viewfinder is every bit as capable as those on many competing DSLRs, the D80 clearly wins on size, brightness, comfort, and flexibility.
The Nikon D60's viewfinder readouts do a good job of communicating camera status and exposure settings: They're a slightly trimmed-down list of information from that found on the D80, making for a simple and relatively uncluttered display. The readout display is identical to that of the D40x, except Nikon has added a very nice focusing rangefinder readout using the analog scale, to assist in more accurately focusing lenses that do not autofocus on the D60. (As mentioned in the Optics section, the D60 will not autofocus with lenses that do not have a built-in focus motor.) Off by default, you can turn on the focusing rangefinder display via custom settings menu option 19. Because it uses the camera's AF sensor, the rangefinder will only work with lenses having a maximum aperture of f/5.6 or wider.
Viewfinder Test Results
Good accuracy from the optical viewfinder.
The Nikon D60's optical viewfinder proved quite accurate, showing about 98% coverage at wide angle, and about 97% coverage at telephoto zoom settings. This is above average coverage for a consumer digital SLR, especially an entry-level model, though there is a slight tilt and vertical offset with respect to the imaging sensor.
Nikon D60 LCD Display
As is the case with other entry-level Nikon digital SLRs, the LCD panel on the D60 can't be used as a viewfinder. It does, however, provide a great deal of information about your pictures after you've shot them. A variety of playback options are offered, including image-only, four flavors of overlaid information, a 4- or 9-image thumbnail display, and a zoomed playback mode with variable information. The screenshots below show several of the information displays that are available.

Of the various screens, one of the more interesting options on the Nikon D60 is the histogram screen. Histogram displays are common on professional digital cameras (and many amateur models now as well), regarded as almost mandatory by many pros for evaluating exposure levels. A histogram is simply a graph of how many pixels there are in the image at each brightness level. The brightness is the horizontal axis, running from black at the left to white at the right. The height of the graph shows the relative number of pixels having each brightness level. This sort of display is very handy for determining under- or overexposure. Ideally, the histogram would stretch across the entire width of the display, using the full range of brightness values available. An underexposed image will have a histogram with all the data lumped on the left-hand side, with nothing reaching all the way to the right. Likewise, an overexposed image will have all the data lumped on the right hand side.
A histogram display is very helpful in telling whether you've got the exposure right, but to my mind isn't adequate by itself. With digital cameras, it's very important not to blow-out the highlights in a picture (they're similar to color positive film in that respect), since once you hit the maximum brightness, the image just saturates, and any highlight detail will be lost. A histogram display does a pretty good job of telling you how the image as a whole is doing, but what if there are just a few critical areas that you're worried about for the highlights? If only a small percentage of the total frame is involved, it won't account for many pixels. That means any peak at the "white" end of the histogram graph would be pretty small, and easy to miss (or just plain invisible). What to do? The folks at Nikon recognized this problem some time ago, and so have provided another special display mode on the D60 (as on most of their dSLRs) that they simply call "highlights," accessible via the Playback settings menu, under "Display Mode." This mode blinks any highlights that are saturated in any of the color channels. It does this by taking the nearly-white areas on the LCD and toggling them between white and black. The shot above left shows the blown highlights blinking on an otherwise uninteresting shot.
