Sony engineers did a remarkable job to maintain the low-light performance of the camera. Despite of increase in the resolution (We all know as the resolution increases the photodiodes sizes gradually decreases resulting poor low light performance ) Sony A7R IV camera is able to deliver same ISO range as we have in the Sony A7R III.

We do have slight improvement in the external video recording mode of the Sony A7R IV camera, now you can record DCI 4K video in Sony A7R IV camera which was limited to UHD 4K in Sony A7R III.

The Sony a7R IV can capture full-frame 4K oversampled from 6K, that clearly means no pixel binning and you are getting maximum image quality possible. However, Sony A7R III also uses the same process to create 4K video.

So, we don’t have any major difference in the Video quality of both the camera despite of enjoying a major specs upgrade in the still part of A7R IV.

    Interesting and fantastic comparison. With the operational capabilities offered by both the new HARDWARE and the SOFTWARE of the 7R4, I understand that the competition is going to be very difficult, and will have a very fine spin on the presentations of their next models. From my point of view the Sony 7r4 represents “the square of the circle”. What definition of image with 61 MG !!!

    Interesante y fantástica comparativa .

Desde mi punto de vista la Sony 7r4 representa “la cuadratura del círculo”. Que definición de imagen con 61 MG ¡!!.

  • Please confirm if I can buy an adapter to use my Canon telephoto lenses? I am a wildlife bird photographer and am getting frustrated as Canon still have nothing new (DSLR) camera bodies on the market, so I want to change to Sony but I have only Canon lenses which are excellent.
