Nikon Coolpix S4 Overview

By: Stephanie Boozer
and Dave Etchells
Review Date: 11/03/05

The Nikon Coolpix S4 is the latest in a long line of Coolpix digital cameras whose popularity stretches back to the original Coolpix 900, Nikon's first "breakthrough" digital camera. The new Nikon S4 features one of the original Coolpix design elements, with a swiveling lens that faces a wide range of angles.

The Nikon S4's 6.0-megapixel imager means it can capture high resolution images, and its 10x zoom lens gives you quite a bit of flexibility. All in all, it's an excellent "take-with-you-everywhere" digital camera, with a compact size that travels well. With its range of user-friendly, point & shoot exposure modes, the Nikon Coolpix S4 can handle just about any photo opportunity you're likely to throw at it. Read on for all the details!

 

Nikon Coolpix S4 User Report

Returning to the tried-and-true swivel lens design that proved so popular in early Coolpix models, Nikon introduces the Coolpix S4. The new "twist" is that this twist packs a whopping 10x optical zoom into a small camera body. The Nikon S4 features the same swivel lens design that differentiated past Coolpix models from the digital camera pack, a design that lets you point the lens in almost any direction without losing your LCD monitor view. Though a little long for most average shirt pockets, the Nikon S4 is still fairly compact, especially considering the 10x lens it boasts. Measuring 4.4 x 2.7 x 1.4 inches (111.5 x 68.5 x 87 millimeters) with the lens in its storage position, the S4 weighs only 7.2 ounces (205 grams) without lens cap, batteries, or memory card. Since the Nikon S4 has only a tiny ridge on the front panel for a handgrip, I recommend keeping the included wrist strap securely around your wrist when shooting. The camera's plastic lens cover is actually hinged on the side of the lens, with a flip-open design. When opened, the cover itself can fold backward and out of the way, and its attachment to the lens barrel means you need not worry about losing it accidentally. The camera's silver body is smooth, attractive and fairly simple, housing a 6.0-megapixel CCD that captures high quality images. Other noteworthy features of the Nikon S4 include a macro mode capable of focusing as close 1.6 inches, and no fewer than 16 preset shooting modes. Since the camera operates mainly under automatic control, its control layout and menu display are very user friendly.

The Nikon S4 features no optical viewfinder, only a large, bright, 2.5-inch color LCD monitor for framing. The camera's 10x, 6.3-63mm zoom lens (equivalent to a 38-380mm lens on a 35mm camera, a conservative wide angle to very long telephoto) offers a maximum aperture of f/3.5. The camera uses contrast-detection autofocus in normal mode, which ranges from 1.0 feet (30 centimeters) to infinity. Auto Multi-point AF selects the closest object, though it doesn't report more than an AF confirmation dot. In Macro mode, the camera focuses as close as 1.6 inches (4.0 centimeters), and automatically switches to continuous AF mode, focusing constantly when the Shutter button is not half-pressed. (Note that closest focusing is possible only when the lens is set to a fairly narrow range of focal lengths toward the wide-angle end of its range. The zoom indicator that appears at the top of the LCD when zooming and the "tulip" macro icon both turn green when the zoom is set within the optimal range in Macro mode.) In addition to its 10x optical zoom, the Nikon Coolpix S4 offers a maximum 4x digital zoom, which lets you "zoom" in even closer (equivalent to a 1,520mm lens on 35mm camera). As always though, keep in mind that the digital zoom simply enlarges the center pixels of the CCD, resulting in lower image quality. The 6.0-megapixel CCD produces high-resolution images, good enough for printing to 11x17 inches with good detail, as well as lower-resolution images for sending via email or printing as 4x6-inch snapshots.

In keeping with the tradition of the entry-level end of the Coolpix line, the Nikon S4's exposure control is very straightforward. Operating mainly under automatic control, the Coolpix S4's user interface is easy to learn. Most of the exposure options are controlled through the multi-page LCD menu system, although a handful of external controls accesses basic features. A Mode switch on the top panel controls the operating mode, with three positions: Auto, Scene, and Movie. The Framing Assist modes are optional in Portrait, Landscape, Sports, and Night Portrait modes through the Scene menu, each offering a range of framing scenarios. For example, under Portrait mode, you can set up the framing for a centered single subject, a single subject off to the right or left, a close-up portrait, two subjects positioned side-by-side, and a figure shot with the camera held in portrait (tall) rather than landscape (wide) orientation. Once a specific setup is chosen, faint yellow subject outlines appear in the LCD monitor to help you line up the shot for the best focus, framing, and exposure. Face-priority AF is another option under portrait, where the camera analyses the scene and puts a square around each face it sees, choosing to focus on the face closest to the camera. (This is pretty interesting, because if you move the camera, or if the subject moves slowly enough, the square will actually move to follow the face.) Sports mode offers enhanced options for capturing fast-paced action, such as a rapid fire mode that captures 16 tiny images in two seconds that form a single 4x4 image mosaic. Other Scene modes are Party/Indoor, Beach/Snow, Sunset, Dusk/Dawn, Night Landscape, Close-Up, Museum, Fireworks Show, Copy, Back Light, Panorama Assist, and Voice Recording. Each scene mode sets multiple camera options to configure it for the specific type of subject and shooting condition chosen. In Voice Recording mode, you can get about 29 minutes of audio on the camera's internal memory.

The Nikon Coolpix S4 offers a few exposure options. Though no mode allows the user to control the aperture or shutter speed directly, the exposure compensation adjustment can be set in Auto mode to deal with high contrast, dark or light subjects. The Exposure Compensation adjustment optionally increases or decreases overall exposure from -2 to +2 exposure equivalents (EV) in one-third-step increments. It is not reported on the LCD display, but the Coolpix S4's shutter speeds range from 1/1,000 to 2 seconds. A White Balance adjustment offers five preset modes, an Auto setting, and a Custom setting for manually determining the color balance. The Nikon S4 uses a 256-Segment Matrix metering system to determine exposure, evaluating the contrast and brightness across the frame to determine the best exposure. ISO light sensitivity can be manually adjusted to 50, 100, 200, or 400 equivalents, or you can choose the Auto ISO setting. (Note though, that the camera doesn't report its automatically chosen ISO value to the user while shooting.) You can also access Nikon's Best Shot Selector mode, which automatically chooses the least blurry image in a series shot while the Shutter button remains pressed. (The Best Shot Selector feature is one of my all-time favorite digital camera features, as it makes it possible to hand hold even very long exposures by playing the odds that during one of those moments you're going to be still enough to get a sharp image.)

The Nikon Coolpix S4's built-in flash is rated as effective from approximately 1.25 to 10 feet (0.4 to 3.0 meters) depending on the lens zoom setting. The S4's flash operates in Auto, Red-Eye Reduction, Anytime (Fill) Flash, Flash Cancel, and Slow Sync (night) modes. An option in many modes, Slow Sync combines the flash with slower shutter speeds, letting more of the ambient light into the exposure, making for brighter, more natural-looking night shots. In some Assist and Scene modes though, the flash mode is automatically set for you. Portrait Assist, for example, defaults to Red-Eye Reduction mode but can be overridden, while in Night Portrait Assist the default Red-Eye Reduction can not be overridden. Night Portrait Assist and the Scene modes Night Landscape and Dusk/Dawn also enable an automatic Noise Reduction feature to eliminate excess image noise resulting from the higher ISO sensitivity and longer exposure. Flash is also not available in Sports or Landscape modes. While this panoply of default flash modes and constrained options may sound complicated, the net result is that the camera's scene modes let average users bring back good-looking photos from tricky shooting conditions, while enjoying point & shoot simplicity.

Most digital cameras these days have special red-eye reduction flash modes, which pop the flash (or blink a bright LED) a few times before the shot itself, to make the pupils of your subject's eyes contract a little. This reduces the likelihood that light from the flash will reflect off the insides of the subjects' eyes, causing the dreaded red-eye. The Nikon Coolpix S4 goes quite a bit beyond the simple pre-flash red-eye reduction approach though, as it also incorporates special software inside the camera that can look for and remove red-eye before it saves the images to the memory card. While I don't have a standardized anti-redeye test (for whatever reason, our eyes here at IR just don't seem very prone to redeye), I can attest that the S4's system does indeed seem to remove red-eye very well when it's enabled, vs when it's disabled. The one downside to the Nikon S4's approach though, is that the post-processing that the camera uses to search for and remove any remaining red-eye takes an appreciable amount of time, resulting in a rather long delay before you can capture the next shot.

Another really unique feature of the Nikon S4 is its innovative "D-Lighting" option. This is a Playback-mode option that could be thought of as a "virtual fill-flash," in that it brightens shadow areas. There are a couple of important differences between D-Lighting and on-camera flash though. First and foremost, it brightens all the shadowed areas in the image, regardless of how far they were from the camera (that is, there's no light falloff as you'd have with a flash). A second point is that this is a post-capture option, one that makes a copy of the image with the D-Lighting effect applied, so your original image is undisturbed. On the downside, a third key factor with D-Lighting is that it will make image noise more apparent in the areas that it's brightened.

D-Lighting Examples

With Without
(as-shot)

D-Lighting's effect on images is generally pretty subtle, as you can see from the two examples above (borrowed from my review of the Coolpix 7900 - The function works identically on the S4.) In the situations where you'd want to use D-Lighting though, subtle is good, you ideally want the image to look natural, as if nothing unusual was done to it.

Other camera features include a Self-Timer mode, which provides a 10-second delay between the time the Shutter button is pressed and when the image is actually captured. A Continuous Shooting mode captures a rapid series of images while the Shutter button is held down, with the actual number of images dependent on the size and quality settings, as well as the amount of memory card space. There's also a Multi-Shot 16 mode, which captures 16 thumbnail images in sequence, arranged in rows of four within a full-sized image. The Coolpix S4's Movie mode offers four options: TV Movie 640 (640 x 480, 15fps), Small size 320* (320 x 240 pixels, 15fps), and Smaller Size 160* (160 x 120, 15fps), plus a Time-lapse movie mode. The actual length of recording time depends only on the amount of available SD card space (there is no arbitrary limit set by the size of the S4's internal buffer memory), and appears in the LCD monitor. Movie mode also offers Electronic VR (vibration reduction), which attempts to reduce camera shake in the movie file due to normal handheld camera movement.

The Nikon Coolpix S4 stores images on SD memory cards, but the standard retail package in the US includes no memory card. There is enough onboard memory, however, to hold up to about four full resolution pictures according to the user manual. Files saved to internal memory can be easily copied to an SD card, and vice versa. Given the camera's large 2,816 x 2,112-pixel maximum image size, I strongly recommend picking up at least a 128 - 256MB memory card so you don't miss any important shots. Images are saved in JPEG format, with three compression levels available. A CD-ROM loaded with Picture Project software accompanies the camera, compatible with both Windows and Macintosh platforms (including Windows XP and Mac OS X). Nikon Picture Project provides organization and image editing tools for enhancing images. The camera comes with a set of AA-type Coolpix NiMH rechargeable batteries and a charger. (As always, I recommend picking up a spare battery and keeping it freshly charged at all times, to avoid dead-battery syndrome. - Murphy's law applies in spades to digital camera batteries - They invariably go dead when you can least afford it. Read my NiMH battery shootout page to see which batteries currently on the market are the best, and see my review of the Maha C-204W NiMH battery charger, my current favorite.) The optional AC adapter uses a "dummy battery" that slides into the battery compartment. This could be useful for offloading pictures after a long day of shooting, but really isn't necessary for the vast majority of users. Also included with the Coolpix S4 is a video cable for connecting to a television set for slide shows, and a USB cable for downloading images to a computer.

The Nikon S4 is a combination of a Nikkor 10x optical zoom lens, a 6.0-megapixel CCD, and a range of automatic, preset shooting modes in a fairly small and slim digital camera. Automatic exposure control lets the camera take charge of all the picky details, although a handful of exposure options provides creative tools when you need them. While it won't fit into most shirt pockets, the Nikon Coolpix S4 is still compact enough for travel as well as everyday carry, and the range of preset shooting and framing modes anticipates most common shooting conditions. The 2,816 x 2,112 pixel maximum resolution is high enough for making acceptable 11x17-inch photographic prints (or 8x10 prints with some cropping), while the 640 x 480-pixel resolution setting is perfect for sending email attachments over the Internet. The uncomplicated user interface means you won't spend much time learning the camera. Perfect for novice users or anyone looking for a point-and-shoot camera with a few extra features, great ease of use, and sharp, colorful photos, the Nikon Coolpix S4 could also serve as a great take-anywhere snapshot camera for more advanced shooters.

Nikon's Coolpix line of consumer digital cameras has always been well-received and greatly appreciated for its overall image quality and ease of use. The Nikon Coolpix S4 packs a lot of features, including a 6.0-megapixel CCD with 10x zoom lens, and a surprisingly large 2.5-inch LCD into a fairly compact package. For the average consumer willing to delve just slightly deeper than just pushing the button, its extensive scene modes and unique framing-assist options greatly extend its capabilities, making it easy to bring back good-looking shots of what might otherwise be difficult subjects. While it may be a matter of personal taste, we really like seeing the return of the swivel-body design that was so popular on Nikon's earlier Coolpix models. The Coolpix S4 delivers bright, saturated color that most consumers are likely to find very attractive, yet manages to produce very natural-looking skin tones as well. It handles a wide range of exposure conditions, so should be able to accommodate the shooting conditions encountered by average consumers fairly easily. Its low-light capability isn't best-in-class, is more than adequate for typical city night scenes. We were also surprised to find that its high-ISO capabilities were quite good, with ISO 400 shots usable to print sizes as large as 8x10 inches. Finally, the unique Nikon-only Best Shot Selector is a great help for capturing sharp images in dim lighting without a tripod, and the D-Lighting feature does a great job of opening up shadows, making for much more natural-looking images under difficult lighting conditions. We'd really like to see better shutter response at the telephoto end of its zoom range, as well as somewhat faster shot to shot cycle times, but the total package is nonetheless very appealing. All in all, a very capable and enjoyable little camera that snaps great-looking photos, deserving of its status as a Dave's Pick.
