In 2010, the first mirrorless Japanese "breed" spun off from the Sony Alpha mirror system. They were assigned to the NEX family, the backbone of which was formed by compact cameras with interchangeable objects and an APS-C image sensor. After just a couple of years, the NEX series was reborn into the "thousandth" numbering used in Sony's dropped mirrorless mirrors to this day.

Amateur APS-C cameras of the basic link belong to the five thousandth league of Sony mirrorless cameras, advanced solutions for photo enthusiasts are included in the six thousandth line. However, Sony full-frame mirrorless cameras are still a head above them. They created a revolution in the arena of photographic equipment in 2013 and for a long period of time they single-handedly ruled the ball in the segment of mirrorless fullframes.

For a long time, Sony fullframes have been monopolists in the mirrorless arena of photographic equipment.

It is difficult to distinguish common features of cameras with the letter α in the marking. In fact, everything depends on the low-cost for the purchase and the specific "wishes" of the photographer. In general, the series offers solutions for every taste, colour and thickness of the wallet. It has a good offer for beginners in the world of photography, and for venerable professionals, and for videographers.
