DSLR with video: Change is rarely as dramatic as it appears. In the world of camera makers, the digital onslaught has seen the rise of electronics firms such as Sony, Panasonic and Samsung, while that venerable creator of cameras Minolta has disappeared, sold to Sony.

The usurpers have not completely taken over, with traditional giants Nikon and Canon still slugging it out for the crown of No. 1 digial SLR maker, the upper echelon of digital cameras. Nikon's much-forecasted latest blast in the seemingly never-ending exchange between the pair is its newly revealed mid-level DSLR the D90.

This succeeds Nikon's hugely popular D80, which has soldiered on for two years, an extremely rare longevity for a digital camera. The D90 looks very similar and takes over the difficult but crucial mantle of trying to be all things to almost all people, including beginners.
