Nikon's 2006 wave-design Wi-Fi compact — 6MP CCD, internal 35-105mm equiv 3x ED zoom, 3" LCD, EN-EL8 battery.
The Nikon Coolpix S6 was a design-led slim compact announced on 21 February 2006, the Wi-Fi-equipped flagship of Nikon's first S-series generation and a sibling of the Coolpix S5. Its 'wave' body — a curved front rising into a slight grip — and rotating control disk made it one of the more distinctive compacts of its era.
It pairs a 6-megapixel 1/2.5-inch CCD with an internal 3x ED Zoom-Nikkor equivalent to 35-105mm; the lens does not extend from the body. The 3-inch LCD dominates the rear, exposure is fully automatic, and continuous shooting reaches about 2.2fps. Built-in IEEE 802.11b/g Wi-Fi can push images straight to a computer — novel in 2006. Photos store to SD cards or roughly 20MB of internal memory, and power comes from the EN-EL8 lithium-ion battery.
The S6 appeals to collectors of mid-2000s design pieces and anyone wanting a slim CCD compact with a big screen; the folded-optics lens means nothing protrudes, making it a discreet pocket camera. Its Wi-Fi predates modern protocols and is effectively unusable today, and fully automatic exposure rules out enthusiast control.
Check the rotating control disk for wear and erratic response, the large screen for scratches, and the battery situation: the EN-EL8 is discontinued but third-party cells and chargers remain available cheaply. The Wi-Fi feature should be treated as decorative — it requires period software and open networks. SD storage and USB transfer otherwise keep it usable.
