using DSL as a name. for cameras that can use interchangeable lenses but do not use a preview system built around a reflex mirror mechanism would make it too easy to confuse them with DSLR types.
there are at least three camera designs that aren’t the SLR type: rangefinders, Twin Lens Reflex, view cameras.
I think mirrorless is both a mouthful and not descriptive enough, so I have a better suggestion than DSL: DV. DV is short for Direct View.
After all, what we see in EVF or on the preview screen on the back of the camera is a direct electronic feed from the image recording sensor.
I would argue that the image on the ground glass of a view camera is more "direct" that that in the EVF or rear display of a MILC. You could even argue that the image on the focusing screen of an SLR is more direct than what you get with an MILC.
I owned and used Sinar, Arca-Swiss, Canham, and V-Pan view cameras as well occasionally using Linhof and once or twice Horseman and Toyo view cameras. As direct as what we see(or saw) on the ground glass of view camera is, the ground glass isn’t the device that will be recording the image.
With a view camera the projected image is also reversed (because that is how lenses project an image) in both vertical and lateral directions.
And yes I understand that the image we see when looking at either in an EVF, on the camera monitor, or on a larger monitor, is a JPEG version based on the settings the factory or you programmed the camera to produce, and not the actual “raw” data. And that the image will look different once you run it through your raw processor of choice according to how that program’s developers ideas of what a processed raw image “should” basically look like. But it is closer to being a direct view of what the basic image will look like than I remember seeing on a ground glass, or through the viewing system in an SLR, DSLR, or rangefinder.
The problem I think many photographers face is that they take the interpretation seen through an EVF or on a camera monitor as being the absolute version of what the photo
should look like.
