Overview of the mirrorless camera Sony a7R III: pride without prejudice
Sony a7R II over the past three years did not really have time to date. Yes, during this time, came out and Canon EOS 5D Mark IV and Nikon D850 that also offer enviable versatility: and a huge image resolution and decent refinement at high ISO, and the ability to use for professional shooting 4K video. Yes, it’s all in the body of an altogether different size and no built-in stabilizer, but Sony, apparently, was concerned about the higher burst speed direct competitors.
Well, the time

Appearance and ergonomics
Sony is not trying to flirt with design refinements and reinvent the wheel for each camera. In fact, for a series of full-frame besserglik the company has only one option of the case – and it is used with small changes that all a7 on a9.
In this case, the dimensions of a9 are identical in width and height, but the a7R is a little thicker III – 10 mm. What is the reason, hard to say, controls on the “seven” compared to “nine” became even smaller (gone was the pyramid of the selectors on the left side of the top bar).
Everything else remained the same: and three soft keys, and two of the selector disk, and the combination of keys and selectors on the rear panel. This is logical – after years of suffering with NEX’AMI Sony finally found a working circuit, and to rush in search of something better yet to anything.
Body Sony a7R III is partly made of magnesium alloy, and partially of plastic. Full dust and moisture protection should not count – it is not a weatherproof camera. Light rain or snow she’ll survive, but under the shower maybe “leaking” — not enough density plug ports. Although memory cards nothing will happen – compartment for them just fortified enough and closes the “valve”.
Sony a7R III weighs 657 grams – for a mirrorless camera with interchangeable lenses that’s a pretty big number, but you can see in the table of characteristics of its direct competitors. Almost double the winnings, mirrorless still remains itself. Count on lightweight optics for E-mount it is not – then the Sony lenses are quite comparable with competitors Canon and Nikon, and in some cases harder. Yes, the whole system will be smaller and lighter – but the dramatic win.
The ledge to grip with the right hand large enough relief and, of course, covered with a rubberized material. The distance between the protrusion and the lens sufficient the knuckles did not Balk at the optics. On the back there is a Playground for the stop with the thumb, performed in the same manner.
On the front panel is the lens mount, release button lens selector disk (placed on the handle for grip), IR transmitter for wireless remote control and lamp the AF-assist illuminator.
On the right side is a compartment for memory cards. The top slot is suitable for cards Memory Stick and SD, the bottom – only for SD. There is also a contact pad for NFC.
On the left side are all the interfaces are divided into three groups, each of which is covered with its cover. The first is the sync terminal for external flash and a mini-Jack for microphone. The second mini-headphone Jack and microHDMI. The third USB Type-S for quick transfer of files to computer (USB 3.0), and microUSB for charging.
The top panel is a speaker, stereo microphone (on each side of the “hump”), universal interface “hot Shoe” and a group of controls, concentrated in the right side: classic mode selector operation, the wheel input exposure compensation, shutter release button with reed — switch and two soft keys.
The bottom is only the battery compartment and tripod socket. They are located at a sufficient distance from each other, the photographer had access to the battery even when shooting with a tripod.
On the rear panel – LCD display, inclined in a vertical plane. Over them – the eyepiece of the electronic viewfinder with diopter correction wheel and a proximity sensor. And the second group of controls: third soft key, the call button on the main menu, press start videos, forced activation of the autofocus/zoom, exposure lock/zoom out while browsing, the second selector disk, a joystick, navigational ring with four “rays” reacting to pressing, and the Central confirming button, function key (by default, it invokes the quick menu) and keys view and delete pictures. The latter is also programmable.
