Smartphone Viewfinder
These cameras are designed to use a smartphone as the viewfinder. With a phone that has a wide-angle lens and an installed viewfinder app, you can compose the view, take an exposure reading on the phone and record a reference image at the same time. The viewfinder is the most important interface between the photographer and the subject. The large and bright screen of a smartphone shows the image crisply and clearly, letting you work even in dim lighting with perfect results.
