Design and features
The S8100 is a refined update to the earlier, equally zoomycamera. It's a slick-looking camera, with a soft-touch casing around the front and a 3-inch screen at the back. At the top is a mode dial with full automatic mode, plus a myriad of scene modes, backlighting mode and a continuous shooting mode. There's also two dedicated night modes on the dial, for portraits and landscapes taken under the cover of darkness. An instant-on video record button is provided around the back.
Improvements over the older model include a new backlit CMOS sensor and the inclusion of full HD video recording. The sensor allows the camera to take a quick succession of shots at 10 frames per second and like other backlit CMOS sensors, is designed to be better at taking clear night images. The sensor also allows the S8100 to take videos at different frame rates, including slow motion at 240fps or 120fps (there's also 60fps or 15fps options). An in-camera HDR mode is provided, too.
The other number to get excited about is the 10x optical zoom, packed on the front of a slim chassis that measures just 2.9cm deep. That said, the lens isn't particularly captivating, remaining the same as found on the S8000. Its widest is just 30mm, which isn't exactly great for landscapes and sweeping vistas, and its maximum aperture is an unexciting f/3.5-5.6. Still, it does better than the Canon IXUS 1000 HS's lens which tops 36mm at its widest.
Like all Nikon Coolpix cameras of late, the S8100 doesn't have a battery charger. Instead, the USB cable doubles as the charging cable, and all recharging is done with the battery still in the camera. Connectivity is provided via the proprietary USB AV out and mini-HDMI.
There are heaps of continuous shooting modes to choose from on the S8100. Also, acting like a pre-record button on a camcorder, the S8100 can take two images before the shutter button is fully released, meaning you are more likely to get your desired shot. (Credit: CBSi)

Note that the S8100 can only take five shots at its full 12-megapixel resolution at the 10fps speed. Nikon rates the battery for the S8100 at 210 shots, or one hour and 20 minutes of HD video.
It's clear that Nikon has worked hard to improve the overall image quality from this camera over the previous version in the S8000, due to a new sensor. Images are cleanest at low ISO levels, but there's still a noticeable film of digital noise even at ISO 160 when viewing images at full magnification. That said, unless you are making large prints or tight crops with images from this camera, you probably won't notice this issue.
As the lens itself hasn't changed, the S8100 still exhibits the same issues found on the earlier camera, including chromatic aberrations on video and slight flaring during longer exposures. On the plus side, night photo modes worked reasonably well with best results obtained during twilight hours, or when there's still a small amount of ambient light from the sky. The S8100 had a reasonably good dynamic range, but like the IXUS 1000 HS, highlights sometimes blew out.
