Maximum Magnification Camera Lens. *however*, on the crop camera the field of view is. If the object is 1mm long, it would be exactly 1mm long when projected to the sensor.

Globular clusters and the smaller nebulas are best at about 12x to 15x per inchof aperture, while 8x per inch of aperture is usually best for finding galaxies and observing large nebulas. The close focus limit is still 360mm, but now the field of view is 180mm / 1.6 = 112.5mm wide. Most standard zoom lenses give a maximum magnification factor of about 0.3x.

Similarly, a camera lens is never characterized by a magnification but by a focal length and a maximum opening of its diaphragm (for example canon ef 300 mm 1:2.8 l is usm where 300 mm is the focal length and 1:2.8 is the maximum aperture of its diaphragm). If an object is 24mm tall and is projected by the lens as 12mm tall on the sensor, the lens has a 1:2 magnification ratio. If the object is 1mm long, it would be exactly 1mm long when projected to the sensor. Maximum apertures on prime lenses normally range from f/2.8 to f/1.2.
