The D5100 incorporates an amazing array of special effects for use when taking still pictures or recording D-Movie Full HD movies. Selective Color isolates color within the scene, capture details in places too dark for your own eyes using Night Vision, create bright, glowing images filled with atmosphere with High Key, emphasize the mood of a scene using Low Key, Miniature Effect makes a scene look like a miniature scale model and Color Sketch creates color outlines of the subject that are played back as a series of stills in a slide show. The arrival of the D5100 appears to signal the completion of Nikons refresh of its non-pro DSLR lineup. Its feature set and pricing mean that it sits very comfortably between the beginner-friendly D3100 and the high-end D7000 - it's clearly aimed to attract the attention of enthusiast photographers without cannibalizing sales of is sister models. A camera maker can judge the success of its market positioning by seeing how many people are wondering 'which model is right for me?' on discussion forums - and we think a D3100/D5100/D7000 progression would minimize such doubts. The official line is that the D90 maintains its position in the range, but both its naming and overlap with other models suggest that its role is now more one of historical interest than future significance. The D5100 has a very similar 16.2MP CMOS sensor to the excellent one seen in the D7000 but, understandably, loses out on that camera's high-end build and feature-set. So there's no wireless flash control, magnesium alloy build or 39-point AF system but the underlying image quality is all but identical.
