Veteran digital shooters waxing nostalgic for the Nikon Coolpix 900 series will cheer for the Coolpix S4's resurrection of the swivel lens after nearly three years. The S4 comes in a more compact package, with 6-megapixel resolution, a 10x zoom lens, a 2.5-inch LCD, and Nikon's signature ease-of-use features. But a lack of manual controls makes this compact snapshot camera a poor choice for shooting indoors or on the soccer field.

Design
Although the Coolpix S4's shape is reminiscent of earlier Nikon swivel-lens designs, it looks positively Lilliputian next to a classic Coolpix 995. At 115 x 68.5 x 37mm and 205g, the silver-toned Nikon Coolpix S4 is smaller than the 990 by a full inch in every dimension and weighs a little more than half what its digital Dark Ages ancestor did.

Family resemblance aside, this newest swivel Coolpix is an ultramodern implementation of the design. You compose and review on the 2.5-inch LCD; there's no optical viewfinder at all. And, instead of using a flip-up flash, Nikon places a tiny speedlight on the swivel section, immediately adjacent to the lens.

The lens-swiveling action is a big plus for those who hanker for a self-portrait or want to shoot from waist level or overhead. The lens module rotates while the LCD remains facing you. In reverse-view mode, the image flips vertically so that the display remains correctly oriented. The LCD is large enough that you can mount the camera on a tripod and preview the image while photographing yourself using the self-timer.

The Nikon Coolpix S4 requires two-handed shooting. The most comfortable one-handed grip causes the right thumb to obscure the right two-thirds of the LCD; using two hands makes it possible to poise an index finger over the top-mounted shutter release and still manipulate the concentric zoom lever. Nikon also crams a microphone, a speaker, an on/off switch with power light, and a sliding mode switch (recording, scene selection, and movie) atop the right-hand section.

The back panel, not much larger than the LCD itself, has four buttons and a four-way rocker switch that navigates menus and controls the self-timer (left), the flash options (up), and the macro mode (down). The button array adjusts display-info options, deletes the current image, activates the menu system, and shifts into playback review. With this minimalist set of controls, you'll need to visit the menus to change exposure (plus or minus 2EV in 1/3EV increments), white balance, ISO sensitivity, and other settings. The well-designed menus are divided into a two-page shooting menu and a four-page setup menu, both with large, easy-to-read text and highlighting.

Features
The Nikon Coolpix S4's 10x zoom lens is its most compelling feature, as most superzoom cameras are a bit heftier. Nikon emphasizes telephoto with its 38mm-to-380mm (35mm-camera equivalent) range, sacrificing a wide-angle perspective. Still, the lens autofocuses as close as 4cm in macro mode, and you can choose from center, multipoint, or automatically selected focus zones.

Like other cameras in Nikon's S series, this one's features favor ambitious snapshooters who crave lots of options but want to make few major decisions. For example, you can take time-lapse photos, create panoramas, shoot close-ups, or select from 16 scene modes, letting the S4 handle the vexing details.

The scene modes take care of the most common shooting situations. There are five for night photography alone (Night Portrait, Sunset, Dusk/Dawn, Night Landscape, and Fireworks Show); others include Portrait, Landscape, Sports, Party/Indoors, Beach/Snow, Close-Up, Museum, Copy, Back Light, Panorama Assist, and full Auto. Several scene modes include onscreen overlays that help perfect compositions for portraits or landscapes.

The scene modes are the best way to customize your shots because the Nikon Coolpix S4 has no manual focus or exposure controls other than exposure compensation; manual ISO (ISO 50 to 400), white balance; and color options, including Vivid, Black and White, Sepia, and Cyanotype (blue). The 256-segment matrix metering system chooses from five F-stops between F3.5 and F13.5 and exposures between 2 seconds and 1/1,000 second.

Nikon's signature features include Face Priority focus, which is especially fun to use the first time you try it. In this mode, a square happy face appears on the LCD. When a human face comes into view, a set of brackets chases it around the screen, constantly maintaining focus on the facial features.

You'll also want to explore the Coolpix's in-camera fixes. These include Best Shot Selector, which takes a series of up to 10 pictures and saves only the sharpest or best-exposed version; an effective in-camera red-eye-removal tool; and D-lighting, which can brighten inky shadows in a murky or high-contrast shot and save a copy of the resulting image. You can set the Interval (time lapse) feature to take a shot every 30 seconds to 60 minutes.

The Nikon Coolpix S4 has 13.5MB of internal memory, good for just four full-resolution shots. Nikon positions this as an emergency feature, useful when your memory card fills--sort of like the backup gas tank on '50s-era cars without a fuel gauge. Plan on buying a Secure Digital (SD) memory card when you purchase this camera.

Despite the generous amount of power available from the AA cells this camera uses, the electronic flash is good out only to 3m (ISO unspecified). You can choose from flash off, fill flash, auto, auto with red-eye reduction, and slow sync. While you can choose between single and continuous autofocus for your image-stabilized 640 x 480 movie clips, you'll be shooting movies at a jerky 15fps.
