Picking out the best digital camera from the massive selection on offer can be intimidating. So it's easy to understand why well-known, market leading brands such as Nikon have such a die-hard following.

While nobody doubts the quality of Nikon's optics, the meagre 1.5-inch screens on the CoolPix range (the smallest available on any compact) has been a source of frustration for reviewers and buyers.

So we're glad to report that the 5900 finally sports a screen to shout about. The new two-inch display brings the CoolPix bang up to date.

The innovation doesn't end there though, as the 5900 also incorporates a number of new features such as 'face priority' autofocus and 'dynamic lighting', both designed to make point-and-shoot photography even easier and more rewarding. Face priority will obviously be a big help to portrait photographers. The CoolPix 5900 was announced at the same time as its more powerful 7.1 megapixel sibling, the 7900, but what makes the 5900 unique is that it's available exclusively through Jessops.

The overall design of the 5900 remains the same as many of Nikon's compacts of recent years, with a grip on the left-hand side and the mode dial easily accessible on the top. The majority of the body is constructed from metal, giving the camera a solid, reliable feel. One disappointment is the tripod mount, which isn't central to the lens and is made from plastic. The larger screen has meant the back of the camera has had to be re-designed, and while the controls have been squeezed together, the operation remains the same.

Whether you're a fan of them or not, the CoolPix range continue to offer an optical viewfinder. Concealed within the menu is the option to disable the larger screen to further extend the battery life; not that you should need to, however, as the 1,100mAh Lithiumion cell claims an impressive 220 images on a single charge.

Another reason to keep your screen turned on is the fact that the sizeable display offers an impressive 100 per cent image, compared to the disappointing 75 per cent coverage of the viewfinder. Nikon has cleverly removed one of the last stumbling blocks of Lithium-ion batteries by offering a 100 to 240 volt worldwide battery charger, and by making the camera compatible with the single use CP1 Lithium batteries, ideal for anyone going off the beaten track.

The only obvious improvement that Nikon could make here is a better battery life indicator, as the current one only shows when you're almost out of juice (typically miles from a power supply). At first glance, the other connectivity options look limited, but closer examination reveals that Nikon has combined the function of the USB and A/V sockets into one port. You still need to keep track of two cables, but it does mean the sockets are easier to protect on the camera body. On the opposing side to the USB port is a similarly sized rubber stopper, which can be removed to connect the camera directly to the mains, via a modified battery.

Rather than simply tacking on new features to an aging model, the CoolPix 5900 feels entirely new, and much faster to use. This leap in performance is underscored by the threesecond start-up, minimal shutter lag and faster menu navigation, but the most obvious additions are the new image overlays. For example, selecting 'portrait' mode gives you the choice of seven different focal modes.
