The Nikon Coolpix S9100 is a pocketable superzoom compact from Nikon's S-series, released in 2011 to give travellers a long reach lens in a slim body without stepping up to a bridge camera.
It uses a 12.1-megapixel 1/2.3-inch backside-illuminated CMOS sensor paired with an 18x optical zoom lens equivalent to 25-450mm at f/3.5-5.9, a 3-inch LCD with 921,000 dots, sensor-shift image stabilisation, and Full HD 1080p video recording.
The long 18x zoom in such a thin body was its main selling point, letting travellers cover wide interiors through to distant subjects without carrying a second lens, at the cost of a smaller sensor than dedicated superzoom bridge cameras.
It remains a popular budget travel-zoom on the used market. Buyers should test the zoom lens for barrel wobble or grinding, check the LCD for scratches, and confirm image stabilisation is working, since these small zooms see heavy use.
