Sony A7R aka Sony ILCE-7R:

The Sony ILCE-7R (aka Sony Alpha 7R, or Sony α 7R for short) is a very interesting and unusual camera. It was presented on October 16, 2013 along with its younger 'sister' – Sony a7 and 5 full-frame Sony-E mount lenses.

The Sony ILCE-7R and Sony ILCE-7 are the first full-frame mirrorless cameras with interchangeable lenses and autofocus, although, even before their appearance, Sony managed to present the first full-frame mirrorless compact camera Sony Cyber-shot DSC-RX2012 in September 1 (of course , without interchangeable optics).

For many users, the Sony a7R is simply interesting as a digital backdrop for manual optics. The camera has a short working distance and therefore theoretically any lens can be mounted on it. By the way, videographers can also use any cinema lenses on Sony a7R. For cameras with E-mount, third-party manufacturers even make adapters that allow you to use autofocus optics from other manufacturers.

The camera weighs about 465 grams, so with a serious body kit there may be inconvenience with the distribution of weight.

Of course, the Sony a7R uses an electronic viewfinder itself EVI quite pleasant at 2.359.000 points with an increase of 0.71x. On Sony a7R, I personally do not like a long time to initialize image output to EVI or camera display. You can also see through a 3-inch deflectable display at 1.230.000 points.
