Sony Alpha 7R V

An 8K video mode, AI-assisted autofocus, and all that at 61 megapixels resolution: The Sony Alpha 7R V once again massively raises the bar in the professional segment of the Japanese camera and electronics giant. The backside illuminated 35mm sensor, together with the Sigma fp L, continues to spearhead the megapixel race of full-frame cameras.

The image processor is called BIONZ XR, which has already been known since the Alpha 7s III. However, according to Sony, it is now supported by an extra processor that is responsible for artificial intelligence (AI). Although the Sony A7R V does not offer artificial intelligence in a literal sense, the autofocus has been trained with the help of Deep Learning algorithms and now understands human movements. This means that movements can be better predicted and entire bodies can be recognized, not "just" the head and eyes. Whether wearing a helmet, mask or from behind: The autofocus recognizes people in almost any everyday situations.

Many small improvements please photo and video enthusiasts: The camera can be permanently powered via the now twice as fast USB-C port (10 Gbit/s) and can be used as a premium webcam without additional software (UVC/UAC mode)! Meanwhile, an HDMI port of the larger type A should make eyes light up in the professional segment.

Continuous shooting continues at a rather leisurely 10 fps, but the 5th generation Sony Alpha 7R offers significantly more endurance and that in two dimensions: Sony finally introduces lossless compressed RAW, which results in significantly smaller files without compromising on image quality - less work for the memory card(s). In addition, even faster memory cards are supported than before.

CFexpress or SD Memory Cards?

The Sony Alpha 7R V has two memory card compartments. Both can accommodate either an SD memory card (UHS-II support) or a CFexpress type A memory card. Like other Sony cameras with the BIONZ XR image processor, the Sony A7RV achieves impressive write speeds of around 240 MB/s with the fastest, UHS-II-capable SD memory cards. In combination with lossless RAW, even longer continuous shooting isn't a problem.

The maximum possible endurance is without a doubt available with CFexpress memory cards. However, the type A form factor currently only used by Sony has two disadvantages: No handful of manufacturers offer corresponding memory cards, which increases the price fivefold compared to the type B used by almost all other camera manufacturers – and that at half the performance! In addition, a maximum of 320 GB is possible as of 12/2022, while companies like Angelbird offer the first 4 TB models for type B.

Fortunately, the Sony Alpha 7R V is also frugal in video recording, so cheaper SD memory cards can be used for long shooting days. SD cards for 8K or All-I video recording (XAVC S-I) are marked with an symbol in the table. For regular HD and 4K video recordings, speed class U3/V30 is already sufficient - corresponding SD cards are marked with a symbol. Sony requires class V60 for high-quality slow and fast motion recordings, which we can quickly recognize with the symbol.
