Mirrorless Interchangeable-Lens Camera (DSLM) is a camera that often used to deceive the consumers with a DSLR look, it has interchangeable lenses like DSLR. This category appeared in 2008 and is expanding from early 2010s. The market is now occupied by the majority of manufacturers but primarily by Panasonic, Sony, Samsung – whose one of the primary area of business was manufacturing prosumer to professional grade video equipments. Instead of using the full terminology – Mirrorless Interchangeable-Lens Camera often the short form DSLM is printed or inscribed or typed in official places including documentations, the body and the deceiving websites. A Mirrorless Interchangeable-Lens Camera (DSLM) can deceive even an experienced if not checked by taking it on hand. The hallmark of this category camera is a small sensor (?4/3, APS-C) and interchangeable lenses with a high pricing range. The produced images looks better for closer shots with same focal length at particular points because of the crop factor. The notable features of a SLR or DSLR are totally absent.
Basics About Mirrorless Interchangeable-Lens Camera (DSLM)
Various brands give various neologism – Compact System Camera (CSC), Mirrorless System Camera (MSC), Digital Single Lens Mirrorless (DSLM), Digital Interchangeable-Lens System camera, and finally Electronic Viewfinder with Interchangeable Lens (EVIL) but the major point or rather the advantage of a typical DSLR – looking through the viewfinder means optically looking through the lens is absent. Sometimes a deceiving optical viewfinder is also used. The history of this segment of devices began in 2008 when Panasonic and Olympus ‘discovered’ a new sensor format : micro 4/3, which will create small digital cameras close to SLR but simplified because no reflex viewfinder is accessible. The segment started with Panasonic Lumix G1 and Olympus PEN E-P1.

The concept is to equip compact interchangeable lenses and sensor sizes as large as smaller sized sensors of DSLR. They are generally equipped with a CMOS sensor from 14 to 24 megapixels pixel count. Because of optical factors, megapixel is somewhat important like Point and Shoot cameras.

The lack of through-the-lens optical viewfinder (TTL OVF) is a defining feature of Mirrorless Interchangeable-Lens Camera (DSLM) and also found on compact cameras “ a TTL optical viewfinder requires an optical path from taking lens to viewfinder, hence an SLR design. The quality of video taken is unexpectedly better and can be compared with EOS 3Ds MKIII, for example. Shutter lag is almost like a Point and Shoot.
