Sony A7 III

The Sony A7 III is inspired by its older A7R III which it takes the main chassis. Whether at the hood or back, it looks like two drops of water to the A7R III. Only the small mode lock button has been removed on this case. There is also the joystick, the video trigger judiciously positioned next to the viewfinder, better organized menus (but still dense) and the double slot for SD cards, only one of which is compatible with UHS-II memory cards, initially borrowed from the A9 – which is also the central reference of this refreshment.

L’excellent viseur Oled de 2 359 296 points a été reconduit. Il n’est pas aussi défini que celui des A7R III et A9, qui grimpe à 3,6 Mpts, mais il reste spacieux, agréable et très lumineux. L’écran affiche une petite baisse de régime, passant de 1 228 800 points sur l’A7 II à 921 600 points. Il reste cependant orientable à 107° vers le haut et 41° vers le bas. Nous déplorons qu’il ne soit toujours pas monté sur rotule pour une rotation à 180°, plus pratique pour utiliser l’appareil en vidéo, par exemple. Le tactile ne progresse non plus pas et permet uniquement de modifier le collimateur AF ; il faudra patienter encore un peu avant de pouvoir naviguer dans les menus du bout des doigts .

On the left shoulder of the case, the lack of keys could have given way to a small control screen, as proposed by the hybrid Fujifilm X-H1: convenient to keep an eye on current settings.

Like the A7R III, the A7 III is powered by the very durable NP-FZ1000 battery of 2,280 mAh inaugurated by the A9. The autonomy announced by Sony is 710 photos with the LCD screen, and 610 with the viewfinder; we recorded from 500 to 600 views (depending on the use of the viewfinder or the screen). The indicator in percentage of the battery level is very useful to anticipate its recharge.

Finally, the connection is complete: USB 3.1 Type-C and standard ports, HDMI, remote control, headset, microphone (3.5 mm jack), Bluetooth, Wi-Fi and NFC. History of well differentiate the housings and their uses, the synchro-flash is reserved for the Alpha 7R III and the RJ45 connector to the Alpha 9.

Qualities of the images

Like the A7 II, the Alpha 7 Mark III incorporates a sensor with a definition of 24.2 Mpx, but here it is renewed: it is a new BSI CMOS Exmor R coupled to the Bionz X processor. is almost the same sensor as that of the A9, but without stacking, that is to say without integrated DRAM RAM to accelerate the processing.

Processor optimization gives the device a sensitivity range of 100 to 204,800 ISO. This is 3 more IL than the previous version and 1 IL less than the Alpha 7S II dedicated to the sensitivity (and last Alpha 7 not to have been renewed for the moment). The A7 III is capable of generating 16-bit data for a 14-bit RAW output, for greater accuracy during post-production.

In the rise in sensitivity, it is from 6,400 or even 12,800 ISO only that the smoothing appears and the image begins to desaturate. Little by little, the electronic noise begins to become more and more visible and, from 51,200 ISO, makes the details completely lost.

The A7 III embodies a formidable 5-axis mechanical stabilization of efficiency. Unlike the A7R III however, it lacks the “Pixel Shift Multi Shooting” mode that offers to capture in RAW four images slightly offset to generate an image at increased resolution. A strategic choice from Sony, again to segment the cameras of the Alpha series by differentiating their uses.


The video mode switches to the higher definition, in 4K / UHD 3840 x 2160 px at 25p and 100 Mb / s. As in the photo, the capture in Super 35 mm is also available. The A7 III includes many advanced features, including an HLG image profile for an instant HDR stream or S-Log3 compatibility. The microphone inputs and 3.5 mm headphone jack are still significant on a case of this caliber to improve sound recording.

Video quality lives up to photo quality. The exposure is correct and the color reproduction is very well controlled. The integration of the 4K / UHD definition brings precision, sharpness and detail to images, compared to the standard definition Full HD.

The video mode of the A7 III meets the expectations of expert photographers who also want to film and access more advanced settings. What to enjoy a little more of the beautiful image quality, mechanical stabilization and accurate tracking of this hybrid. All that’s missing is an orientable and fully tactile screen to make this mode optimal.
