What is a Compact System Camera?
A compact system camera (CSC) is the perfect hybrid of a DSLR’s advanced functionality and a point and shoot’s compact design.
CSCs are built with fewer complex parts than a DSLR, so they have room for a larger sensor than you might find in a point and shoot camera. This sensor is responsible for producing the high quality images you’d expect from a DSLR. With a larger sensor, you can produce pictures that retain their fine detail even when blown up to a poster-sized print. Mirrorless cameras are also designed so you can immediately see what your sensor sees right on the camera screen, offering you the same experience you’d get with a point and shoot.
Like DSLRs you need a lens in order to use a CSC and since you have the ability to change the lens according to your needs, these cameras are sometimes called interchangeable lens cameras. Being able to use the lens that’s most appropriate for your subject gives you better picture quality than a point and shoot can offer. These cameras even have automatic and manual modes, so you have the option to let the camera do all the work or you can take control of the settings to really test your photography skills.
