ABSTRACT
Mirrorless cameras have been around since the beginning of photography. A mirrorless interchangeable lens cameras (MILCs) camera also known as a Compact System Camera can do anything a digital single lens reflex (DSLR) can do; but a DSLR cannot do everything a mirrorless camera can. The one major objection to MILCs will be all but overcome by the time has been published: limited lens selection. For the pro with a lifetime investment in lenses, perhaps the single most important feature of MILCs is that with an inexpensive adapter they can accept lenses from virtually any known lens company. The modern style of 35mm handheld camera became known as the Single Lens Reflex camera. The single most significant difference between the Sony A-series and Nikon Z-series is the redesigned lens mount for the Z-series. Nikon has used virtually the same lens mount with a 44mm diameter opening since the 1950s.
