Nikon has created a new and exciting interactive tool to graphically represent their current lens lineup. The horizontal axis of the chart shows the actual focal length in millimetres, the vertical axis is for the maximum apertures. The lenses themselves are represented by a spot, a bar or a rectangle; depending on whether we are talking about a prime, a zoom with a fixed maximum aperture or a zoom with variable maximum aperture. You can also display product images of the lenses as thumbnails if you wish. Users of the tool can also filter lenses by the size of their imaging circle (DX or FX), focusin method (AF or MF), prime or zoom, and features (such as vibration reduction, internal focus etc.).
