Nikon's 2011 touchscreen compact — 14MP CCD, 5x 26-130mm zoom, 3in 460k touch LCD, 720p video.
The Nikon Coolpix S4150 was a touchscreen-operated compact in Nikon's S (Style) series, released in August 2011 for European markets. Its selling point at a budget price was a large touch-driven interface in place of conventional button-heavy controls, aimed at buyers used to smartphone-style operation.
It built a 14-megapixel CCD sensor into a slim body with a 5x optical zoom NIKKOR lens covering a 26-130mm equivalent range. Nearly all operation runs through the 3.0-inch, 460k-dot touchscreen LCD, including touch shutter and touch AF with subject tracking. Nikon's EXPEED C2 processor drives the camera, video records in 720p HD, and the Smart Portrait System bundles smile timer, blink proof and skin softening. Power comes from the rechargeable EN-EL19 lithium-ion battery and images store to SD, SDHC or SDXC cards.
The S4150 suits casual users who prefer tapping a screen to pressing buttons — framing, focusing and firing can all be done by touch, and the big screen makes reviewing shots pleasant. As with most touch compacts of the period, the resistive-feeling interface is slower than physical controls for changing settings, and small-sensor CCD image quality is best in good light; there is no optical viewfinder.
When buying used, the touchscreen is the critical item: test every corner of the screen for dead zones and check for deep scratches, since the camera is nearly unusable if touch fails. The EN-EL19 battery remains cheap and widely available, so a missing battery is no dealbreaker, but confirm charging works. SDXC support means modern cards are fine; also cycle the 5x zoom and check the flash fires.
