The Nikon 1 series are high-speed
High speed photography
High speed photography is the science of taking pictures of very fast phenomena. In 1948, the Society of Motion Picture and Television Engineers defined high-speed photography as any set of photographs captured by a camera capable of 128 frames per second or greater, and of at least three...

High-speed is characteristic: At the time of announcement it features world's fastest autofocus
Autofocus
An autofocus optical system uses a sensor, a control system and a motor to focus fully automatic or on a manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication...

Frame rate is the frequency at which an imaging device produces unique consecutive images called frames. The term applies equally well to computer graphics, video cameras, film cameras, and motion capture systems...

 even during videos based on hybrid autofocus (phase detection/contrast-detect AF with AF-assist illuminator). World's fastest continuous shooting speed (60 fps) among all cameras with interchangeable lenses including DSLRs completes this. Slow-motion movies can be captured in up to 1200 fps with reduced resolution.

The smaller CX sensor greatly improves the depth of field

In photography, angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view....

). For those preferring a shallow focus
Shallow focus
Shallow focus is a photographic and cinematographic technique incorporating a small depth of field. In shallow focus one plane of the image is in focus while the rest is out of focus. Shallow focus is typically used to emphasize one part of the image over another...

A quadratic function, in mathematics, is a polynomial function of the formf=ax^2+bx+c,\quad a \ne 0.The graph of a quadratic function is a parabola whose axis of symmetry is parallel to the y-axis....

 reduction of the sharpness in the telephoto range gives a solution: For example an 10-100mm or 30-110mm adjusted at 85mm, f/5.2 (230mm full-frame equivalent) gives an equivalent depth of field to an 85mm, f/1.9 mounted at an 35mm full-frame.
