Gerald Undone introduces the Sony a7 V, suggesting it might be the last camera review he ever makes due to the advanced state of modern cameras. He notes that the a7 V, alongside recent releases from Canon, Nikon, and LUMIX, indicates a highly competitive market offering excellent hybrid camera options, making it hard to choose wrong.
The a7 V retains the a7 IV's build but features major upgrades: the best-in-business tilt, flip, and rotate screen mechanism from the Alpha 1 II/a9 III with doubled resolution, and two USB-C ports. One USB-C port is for power, and the other is a 10 gigabit per second port for both power and high-speed data transfer. UVC webcam capabilities are now upgraded to 4K30.
The a7 V features a 33-megapixel sensor with significantly faster read speeds, reducing rolling shutter. It can achieve full-frame, oversampled 4K60 with a read time of 13.1 milliseconds. A new '4K angle of view Priority' setting allows full-frame 4K60 by trading off high ISO noise reduction, which the reviewer finds beneficial due to typically heavy-handed in-camera noise reduction.
The camera's burst speed jumps to 30 frames per second with full subject tracking and no blackout. It retains the Alpha 1 Mark II's 759-point autofocus and AI processing. Three raw modes are available—Lossless Compressed, Compressed, and Compressed HQ. The buffer fills quickly at 30fps (40 lossless, 100 compressed) but allows for longer bursts at lower frame rates, especially for compressed raws at 20fps (over 8 seconds). Sony claims 16 stops of dynamic range in raws.
The a7 V utilizes the new BIONZ XR2 processing unit, combining previous dual-chip and AI chips into one for higher performance and better efficiency. This results in a 23% increase in battery life compared to the a7 IV, rated for over 600 single-frame viewfinder shots, significantly outperforming competitors.
In S-Log3, 4K24 at ISO 800 recorded 14.2 stops of dynamic range. The a7 V's noise profile is more natural and less processed than the a7 IV, retaining more detail after noise reduction. The second native ISO is at 8000, which offers improved dynamic range and reduced pixel noise compared to ISO 6400. In 4K60, the 'angle of view Priority' setting (full frame, less noise reduction) yields similar results to 4K24. Disabling priority (16% crop, noise reduction enabled) matches 4K24's pixel noise and high score. Color rendition is also consistently maintained across the ISO range.
In APS-C mode, 4K24 and 4K60 maintain similar read speeds and dynamic range due to enhanced image sampling. However, 4K120 in APS-C significantly drops dynamic range to typical APS-C levels (about 11.5 stops medium) because the sensor prioritizes speed over enhanced sampling. Detail is well-maintained at higher frame rates. The a7 V shows better chromatic aberration suppression and a subtle, more neutral color science (closer to FX2) compared to the a7 IV, shifting reds and skin tones towards magenta.
While the a7 V struggled slightly earlier in backlit underexposed autofocus (1/3 stop worse than a7 IV), it significantly outperforms the a7 IV in overexposure, tracking up to nearly 7 stops over. It incorporates the latest video autofocus features, including human pose estimation, various subject types, and auto-switching. Stabilization is rated at 7.5 stops. Standard IBIS is typical for Sony; Active IS (slight crop) is smooth for follow shots; Dynamic Active (greater crop) is stellar, almost gimbal-like, and effective even for jogging. Coupled with faster read speeds, this leads to much better handheld footage.
The video briefly transitions to a sponsor segment for Storyblocks, a stock media platform. Following the sponsor spot, the reviewer praises the a7 V's exceptional thermal performance. It recorded for nearly 3 hours continuously in 4K24 and over 2 hours in 4K60 without heat warnings at 22°C (72°F). Sony claims 90 minutes of 4K60 at 20°C (68°F) and 60 minutes at 40°C (105°F), which the reviewer believes given his results. This performance significantly surpasses that of other hybrid cameras, including the Canon R6 Mark III.
New issues include fainter zebras in certain modes. The camera gains the log shooting mode (missing from a7 IV) but retains the quirk of not outputting 4K over HDMI in this mode. Another persistent issue is the LCD screen turning off when HDMI output includes on-screen info. The lack of 25p/30p in H.265 is still present. Positives include a new video interface, importable user LUTs, improved AI white balancing, enhanced Clear Image Zoom, and the ability to create stills in video mode, along with a vertical mode for 9x16 content.
The a7 V lacks Open Gate and internal raw video. The reviewer argues that Open Gate is overrated, particularly for 9x16 reframing, as similar 'headroom' can be achieved by simply zooming out slightly or moving the camera back. Open Gate modes often compromise other features like read speed, bit-depth, frame rates, image quality, battery life, and thermal performance. While Sony could have included it, its absence shouldn't deter potential buyers as the practical benefits are minimal for most users.
As an a7 IV user, the reviewer finds the a7 V delivers on almost all his desired upgrades: less rolling shutter, full-frame 4K60, new screen, better thermals, and updated features. Despite some persistent quirks, he highly recommends the camera. He asserts that the a7 V stands out among its competitors, offering unmatched stability, reliability, performance, battery life, and lens options. He considers it 90% of an Alpha 1 II at less than half the price, with vastly improved stabilization. He concludes that modern cameras, including the a7 V, are all excellent choices.
