SLR-like cameras
The "SLR-like" cameras (e.g. some Nikon Coolpix models, the Sony DSC V, H and R series, the Panasonic FZ series, the Canon PowerShot G, S and Pro models, and several Fujifilm FinePix models) offer through-the-lens (TTL) viewing through the focusing lens, projected onto its viewfinder as well as a LCD screen, through an EVF (electronic viewfinder). The difference compared to a DSLR is that the viewfinder shows a digitally created copy of the TTL image, whereas the viewfinder in a DSLR shows the actual optical TTL image via its mirror. An EVF image reacts slower to view changes and has a lower resolution than an optical viewfinder, but achieves parallax-free viewing using less bulk and mechanical complexity than a DSLR with its reflex viewing system. The limitation of a prosumer digital camera is its fixed lens, typically limited to about a 12:1 focal-length range. The fixed lens also minimizes the risk of getting dust on the sensor.
