“DMC” is best understood as Panasonic’s model prefix for many Lumix digital cameras, rather than a feature or technical specification.

Some people expand it as “Digital Media Camera,” and others have heard “Digital Still Camera,” but based on the answers here, Panasonic has used it mainly as a product-code prefix in its naming system. In other words, it tells you the camera is part of that Panasonic/Lumix line, but it doesn’t describe a capability you should compare between cameras.

So if you see DMC-TZ40, DMC-FZ200, or DMC-FT25, the useful part for shoppers is usually the rest of the model name (TZ40, FZ200, FT25), not “DMC” itself.
