DSLR (Digital Single-Lens Reflex) Model
Definition: An SLR, or single-lens reflex, digital camera is an advanced model targeted at photographers at the intermediate and professional levels. A digital SLR model is often called a DSLR. Those cameras are mainly for photographers with a lot of experiences.
There are some typical things you often see with DSLR cameras, including: image sensors of the large size, full controls over manual settings, interchangeable lenses, flash units outside the bodies, and viewfinders through the lens (abbreviated as TTL). Those models are large and and pretty similar to the 35mm film models that were popularly found in some previous years, with the inclusion of large lens housings as well as handgrips.
The look of a digital model is pretty identical to that of an SLR, but you will see no interchangeable lenses or TTL viewfinder with SLR cameras, which are also known as cameras in the DSLR style or cameras using fixed lens. Such models are mainly targeted at photographers at the intermediate level and sit between point and shoot models and true DSLR cameras.
A new type for cameras which use interchangeable lens has the name of EVIL or DIL, offering a design without any mirror. In terms of the technical aspect, such models have not been recognized as DSLR models
