3.5 stars Very good

The Good Decent photo quality. Curvy body is different.

The Bad On-screen buttons disappear after six seconds. Default settings annoy. Too many quirks.

The Bottom Line The Nikon Coolpix S6400's curvy body is one of its few distinctions. It does a decent job of taking photos, but its interface and other quirks don't make it a particularly endearing camera to have and to hold.

Design and features

While many other compact camera makers churn out relatively boxy shapes that have lightly chamfered, rounded edges, the Nikon Coolpix S6400 tries to make a virtue of its roundness. We're not huge fans of the bulge required to house the lens mechanism, but the S6400 does look attractive in its choice of five colours (silver, black, red, light blue and light purple).

The aforementioned bulge hides a 12x optical zoom lens feeding into a 16-megapixel CMOS image sensor. The S6400's lens is equivalent to a 25-135mm in 35mm speak. Hiding under a flap to the right is the S6400's mini HDMI port (cable not included) and a proprietary connector that can function as either an A/V out or a USB and power jack. Lurking at the bottom is a tripod mount point, which, as is common practice, is not aligned with the centre of the lens barrel. Also on the underside is a door hiding the lithium-ion battery, and an SD/SDHC/SDXC/Eye-Fi card slot. There's 74MB of built-in memory available, and it should be good for around seven photos at maximum resolution and the highest picture quality.

The back of the camera is dominated by a 3-inch, 460,000-pixel resistive touchscreen. The S6400's screen exhibits more flex than other touchscreen cameras that we've used recently, and the amount of warping, especially around the edges, is quite noticeable. To emphasise the camera's touchscreen nature, physical controls are kept to a minimum. Along the top edge, there's a power button, as well as the combined zoom toggle and shutter button. A movie-record button is located to the top right of the screen, and Scene and Playback buttons are near the bottom-right corner.

Four shooting modes are offered via the Scene button: Auto, Scene (portrait, landscape, sports, night portrait, sunset and so forth, as well as auto-selection), Special Effects (a suite of Instagram-style filters, like monochrome, sepia and colour tinting) and Smart Portrait. The latter automatically snaps a pic when it detects a smiling face, and is the only time that face detection is used on the S6400.

On the main picture-taking screen, there are virtual buttons for exposure compensation (up to two stops), macro mode, self-timer (with a two-second or 10-second delay) and flash (auto, auto with red-eye reduction, fill flash, slow sync or off). Annoyingly, though, these on-screen buttons disappear after around six seconds, and if you want them to reappear you'll need to hit either the Display button, which pops up in their stead, or do a half press of the shutter.

One of the great things about touchscreen point-and-shoot cameras is the ability to tap on a focus point, thereby eliminating the usual fussing around with dials, switches and the like. Like many, the S6400 takes it one step further with its (easily switched off) tap-to-shoot function, which allows you to select a focus point and take a photo in one go.

(Longer bars indicate better performance)

According to Nikon, the Coolpix S6400 is able to capture seven shots at around 10 frames per second; we bettered that by some margin.

In Nikon's estimation, the S6400's lithium-ion battery should take 160 photos or record 20 minutes of video. In the S6400's best effort, at least in our presence, it managed to eke out 124 photos and seven minutes of footage before the battery gave up the ghost. Disappointingly, we never saw a flashing battery icon warning us that we were approaching empty; all ever we saw was a "battery exhausted" warning before the camera shut down. By default, the S6400's power-conservation settings are quite aggressive, heading into sleep mode after just a minute of inactivity, and shutting down a few minutes after that.

Image quality

Fresh from the factory, the S6400 isn't set up to make full use of its hardware, as the default photo resolution is 4608x2592. This resolution's 16:9 ratio ensures that the live image from the camera's sensor takes up the entire screen width. The downside, though, is that you lose almost 1000 pixels vertically from the maximum possible resolution (4608x3456). The black letterbox bars at max res, while jarring, are worth the 4 megapixels gained. When you're changing resolutions, don't forget to select the high-quality mode as denoted by the star.

While we're griping about defaults, in its out-of-the-box setting, the S6400 will ask if you wish to apply a filter after ever single photo taken. This setting may please those with a fondness for Instagram, but it's rather wearisome waiting for the message to disappear, or pressing the shutter down halfway.
