Some time ago, many girls dreamed of buying their own DSLR, but very quickly DSLRs became so affordable that today almost every schoolchild can afford an entry-level camera.
Now the time has come for other cameras - mirrorless, with interchangeable lenses. Sony's new cameras have all the best features of a DSLR, while being smaller and lighter.
The size and weight of your camera matters a lot! Few people want to carry a heavy Canon or Nikon with them, so people often find themselves without a camera, and it is at such moments that interesting opportunities are missed.
Sony Alpha cameras - (Sony Alpha A7R and Sony Alpha A7) have a full-frame matrix that has absorbed all the most modern technologies, while the weight of the cameras is 465 and 474 grams, with batteries, but without lenses.
Both cameras are not inferior in their characteristics to the best professional ones. Canon and Nikon... If you need the most modern camera, and you don't want to carry a big heavy camera, feel free to buy new Sony!
