The larger sensor has the smaller crop factor and the higher signal-to-noise ratio.

The other difference is the crop factor.

To address this "crop factor," Pentax created a new series of lenses that were designed only to cover the smaller sensor.

This is due to crop factor.

However, the crop factor can be an advantage to photographers when a narrow FOV is desired.

This extra "reach" does come with the price of some loss of shutter speed, due to the aforementioned "crop factor".

The smaller sensors of Four Thirds System cameras have a crop factor of 2.0.

Some common crop factors are:

The MFT sensor has a crop factor of 2.0 when compared to 35mm film equivalent full frame sensors.

Crop factors for non-SLR consumer compact and bridge cameras are larger, frequently 4x or more.

When the 1.5x crop factor of current Sony digital single-lens reflex cameras is considered, the lens has an effective equivalent 27-105mm focal length.

The smaller sensor is then operating at a lower ISO setting, by the square of the crop factor.)

The camera used Minolta AF A-mount lenses with a crop factor of 2.

As a result, the focal length that can be reliably hand-held at a given shutter speed for a sharp image is reduced by the crop factor.

Such an exercise would in theory produce a lens with the same F-number and angle of view, with a size proportional to the sensor crop factor.

It has a 1.3x crop factor with a CCD image sensor sourced from Panasonic.

The 2x Crop factor of the Micro Four Thirds system means that the field of view is halved.

Like its predecessor, it uses an APS-C sized image sensor, resulting in a 1.6x field of view crop factor.

It is equivalent to adjusting the f-number inversely in proportion to crop factor - a smaller f-number for smaller sensors.

Because of the higher crop factor, an image shot at a given relative aperture and angle of view has more depth of field on Four Thirds.

The small sensor size means that the Q series has a crop factor of 5.6x and a short flange focal distance (FFD).

This crop factor is often called a "focal length multiplier" because the effect can be calculated by multiplying the focal length of the lens.

In this sense, the term crop factor sometimes has confusing implications; the alternative term "focal length multiplier" is sometimes used for this reason.

Crop factor figures are useful in calculating 35 mm equivalent focal length and 35 mm equivalent magnification.

It might be expected that lenses appropriate for a range of sensor sizes could be produced by simply scaling the same designs in proportion to the crop factor.
