Nikon Coolpix 8700

Nikon's Coolpix 8700 is the second digital camera to hit the shelves that features the next instalment of high-density chips that debuted in the hefty, but otherwise functional and desirable, Sony DSC-F828.

Externally, the new Coolpix 8700 shares the same contours as the company's previous top-of-the-range Coolpix, the 5700, but supplants the 5-megapixel chip with a cutting-edge 8-megapixel sensor. Nikon has taken the opportunity to implement several operational enhancements, with a noticeable faster start-up time and shorter-shutter-release time lag being two key improvements. Don't rush to buy it based on that though, as it still takes at least three seconds for the 8x optical zoom to be driven into place after turning on.

Nikon has added an AF-assist lamp (housed next to the pop-up flash gun) for indoor shooting; its absence was criticised in the older model. But it's the superbly detailed and clearly visible electronic viewfinder that's the most appealing new tweak after the jump to a 3,264 x 2,448 image. The magnification could be greater, but the image is so vividly clear that you could be fooled into thinking it's an optical finder.

The screen for the rear monitor has also been upgraded, making it more easily visible under a wider range of lighting conditions. However, as we've seen with other digital cameras recently - Sony's F828 included - strongly backlit subjects result in ugly magenta-coloured streaking across the frame, making it near impossible to compose shots with any accuracy.

Adopting the pro-spec aluminium-alloy body of its predecessor means there's the same high-quality 8x optical zoom nestling within the rigid outer casing. Its gold band around the circumference signifies the use of ED glass elements to minimise colour-fringing, which is welcome, but some might find the lean towards longer focal lengths less useful than the crop of new wider-angle zooms currently on the market. The zoom's range is the equivalent of 35-280mm f/2.8-4.2, and is moderately fast, but hardly stretches Nikon's capabilities. At longer lengths, especially at 280mm, care has to be taken to avoid camera shake with hand-held shots in all but the brightest lighting. Still, it does help keep the camera reasonably compact and discreet. A host of wide-angle and telephoto conversion lenses are available as an optional extra, if really needed. Close-up photography is a cinch, especially as the lens can be zoomed to a short telephoto setting while maintaining its 3cm minimum focus distance, but toggling the macro function on or off from the cluster of small buttons to the side of the body is fiddly, especially if you have large fingers.

The 8700 adopts the company's tried and tested multi-area AF system with the usual focusing modes (continuous, single shot and manual) in combination with five individually selectable focusing points. It's one of the better systems, but the AF frames aren't always overlaid on the screen in correlation with the exposure mode or subject-based shooting option that has been selected. These are chosen from the dial on the top plate, but only after setting up from the neatly labelled menu.

If you're unfamiliar with the menu layout it can be difficult to get the most from it, but in spite of this, the menu gives you control over just about every single operation of the camera. There are plenty of features to satisfy advanced users, including a 2.5fps continuous framing rate at full-resolution for five frames, but the sensitivity range of ISO50-400 is still a little restricting bearing in mind the quality of light in the UK. Noise levels aren't exactly well controlled at ISO400 either, making it a difficult decision to use for some shots.
