Zoom

To focus the lens of a camera such that it appears that a photographer is closer to or farther away from a picture he/she takes. If the photographer focuses so that the subject appears closer, he/she is said to zoom in; if the photographer focuses so that the subject appears farther away, he/she is said to zoom out. Zooming became possible with the invention of the Zoomar lens in 1959.

Our initial tests began with daylight shots from default focal lengths, without zooming in.
Simply put, the Hasselblad True Zoom does not cut into the area of an already small sensor when zooming in on a subject, hence producing the same level of sharpness that it generally produces at default focal length.
It's powerful zooming capacity is certain to attract people with an eye for detail," said Mr.
