1.  In photography, the digital transformation is an irrefutable force. More than their film counterparts, modern digital cameras are faster, reliable and of high quality for a very sensible  cost per exposure. But still there is one facet that photographers keep on criticizing, the size of APS-C sensor. The Advanced Photo System Classic (APS-C) sensor offers more to your advantage than film and digital camera that are “full frame”, though often maligned because its being  smaller than a 35mm negative.

Crop Factor

2.  The APS-C sensor catches a smaller area of the light anticipated by the lens, which causes the center of the image cropped because of the sensor being smaller than a 35mm negative. Technology writer Mark Minasi opines that this crop factor makes lens intended for film cameras behave as if their focal lengths are longer than they actually are. Simply put: Your old 35mm lenses on a digital camera will bring you more closer to the action than they ever did on film.

Optical Quality

3.  APS-C digital sensors uses a lesser  fraction of the image that the lens projects, and that portion was taken from the middle of the image. The pictures taken using the APS-C sensor will have a better sharpness from edge to edge and less vignette than when shot on film or a large sensor digital camera, as the edges of an image often do not have the same optical quality.

Size

4.  The heart of the camera is the sensor, meaning small sensor equals small overall size. APS-C camera lenses are lighter and smaller, also the body of the APS-C camera is not bulky so it is easy to carry by hand.

Cost

5.  APS-C are not just small in size but it is also very affordable. APS-C equipped bodies as compared to full frame digital camera bodies that cost double, even the lenses of the APS-C sensors also is not that expensive as less glass are required for making  these smaller lenses.

Macro Advantages

6.  The APS-C camera system’s “crop factor” has side-effects that are beneficial for macro photographers, says Pbase.com. First, photographers can be up close to small subjects because the APS-C lenses has lesser minimum focusing distance as compared to full-frame lenses. Second, a subject will fill the frame even at a farther distance from the camera because of the small size frame, which for discriminating macro photographer means greater depth of field covered.

Standardization

7.  Available for APS-C cameras are a lot of lenses, in which a number of have exotic focal lengths, which are less expensive generally than that of a full frame. The APS-C design becoming the standard in the photographic industry is one of its final advantages.
