Peilittömistä

Peilittömistä is a Finnish term that translates to "mirrorless" and refers to a class of digital cameras. Unlike traditional digital single-lens reflex (DSLR) cameras, mirrorless cameras do not feature a mirror mechanism and pentaprism that reflects light from the lens into the optical viewfinder. Instead, the image sensor is directly exposed to light, and the image is displayed on an electronic viewfinder (EVF) or the rear LCD screen. This fundamental design difference allows mirrorless cameras to be significantly smaller, lighter, and quieter than DSLRs.

The absence of the mirror box also enables shorter flange focal distances, the distance between the lens mount and the image sensor. This has opened up possibilities for new lens designs and allows for the adaptation of a wide range of lenses from other camera systems using adapters. Mirrorless cameras typically offer advanced features such as sophisticated autofocus systems, high-speed continuous shooting, and advanced video capabilities. The technology has evolved rapidly, with many manufacturers now focusing their development efforts on mirrorless systems due to their inherent advantages in size, performance, and future potential.
