Sony A7V preorders:

In Australia at: Camera Pro, Sony Australia.

PetaPixel listed the 15 biggest improvements on the Sony A7V:

  • New 33MP partially stacked sensor (first ever in an Alpha camera), delivering faster readout and better overall performance.
  • Improved dynamic range up to 16 stops with mechanical shutter (about 1 stop better than A7 IV).
  • Massively reduced rolling shutter: ~15ms vs ~70ms on A7 IV.
  • Continuous shooting upgraded to 30 fps RAW with full AF/AE tracking (A7 IV maxed at 10 fps).
  • Blackout-free EVF even at 30 fps thanks to faster sensor & processor.
  • New Bionz XR2 processor with integrated AI—faster, more efficient, and no external AI unit required.
  • Greatly improved AI autofocus (people, animals, birds, insects, vehicles) with pose prediction & subject recognition.
  • Much better automatic white balance, especially for skin tones, blue skies, and foliage.
  • Full-width 4K60p oversampled video (A7 IV only did 4K60 with APS-C crop).
  • Better video AF, improved stabilization, Custom LUT support, and Auto Framing.
  • Significantly improved thermal performance with a new graphite heatsink—no overheating in 4K60 All-I tests.
  • New 3.2″ 2.09M-dot 4-axis screen (vs 3.0″ 1.04M-dot on A7 IV).
  • Better EVF experience (blackout-free, smoother refresh) even with same 3.69M-dot panel.
  • Improved battery life: 630 shots EVF / 750 shots LCD (vs 520 / 580 on A7 IV).
  • New dual USB-C ports (data + charging simultaneously).

In my opinion, this is a solid upgrade — especially because the fundamentals are now much stronger: a new sensor and a new CPU with an integrated AI chip. With that foundation, there’s real potential for Sony to introduce additional features through future firmware updates.

Weird: Chinese third party E-mount lenses do not work properly on the new Sony A7V

Kai noticed that none of his Chinese E-mount lenses worked on the Sony A7V. Sony’s official response to Kai was:

We do not guarantee third party compatibility

It’s possible the A7V was running non-final firmware, or simply that the Chinese manufacturers will need to update their lens firmware for full compatibility. Many Sony users own these Chinese-branded E-mount lenses, and there’s no reason Sony wouldn’t ensure they work properly on the A7V as well.

Curiosities about the new Sony 7V: New AI driven White Balance system, new AI noise reduction and 10Gbps USB-C

By now you know the camera features the world’s highest-resolution partially stacked sensor, a CPU with integrated AI for higher speed and lower power consumption, 16 stops of dynamic range, excellent uncropped 4K60p, and more. But the Sony A7V also introduces several new “tricks”:

  • The camera uses AI to analyze both visible and infrared light to accurately determine the characteristics of the light source in a scene. For example, in shaded forest environments where older models often produced incorrect color temperatures, the Sony A7V can reliably reproduce neutral whites and natural skin tones. This greatly reduces the time and cost of color-correction work for wedding and outdoor portrait photographers.
  • Overall AI recognition rate improved by 30%. The new system introduces “Human Pose Estimation”
  • Sony is introducing two AI-powered RAW stills processing features through Imaging Edge Desktop software. Composite RAW shooting, inherited from the a1 II, combines multiple exposures into a single high-quality RAW file, suited for landscapes and nighttime photography. New to the a7 V is Extended RAW processing, which uses neural networks to generate high-resolution images from a single input, making it suitable for fast-moving subjects like wildlife where multi-frame capture isn’t practical.
  • The camera features dual USB-C ports on the side: one supports 10Gbps high-speed transmission (suitable for tethering), and the other is a dedicated USB 2.0 port for power or communication. The wireless network has been upgraded to Wi-Fi 6E (6GHz) with a 2×2 MIMO antenna, significantly improving transmission speed.

Don’t order the Sony A7V with the new 28-70 II lens…it’s going to ship out mid Feburary only

Sony A7V preorders:

Unless you’re willing to wait two months (!), I wouldn’t preorder the Sony A7V bundled with the new Sony FE 28–70mm f/3.5–5.6 OSS II, as that lens won’t be available until February 16.

What’s new on this lens? Sony issued a vague press release:

Compact, lightweight, and engineered for speed, the FE 28-70mm f/3.5-5.6 OSS II is designed to fully leverage the continuous shooting19 capabilities of the Alpha 7 V sensor. When combined with compatible cameras, this new lens offers up to 120 fps AF/AE tracking20, continuous shooting, seamless body-lens coordinated image stabilization, AF available even during zooming, and built-in breathing compensation support. From dynamic action shots to fast-paced events or high-quality video capture, this lens delivers smooth, dependable responsiveness and flexibility.

There are no optical improvements on this lens. What has improved is the speed o the lens that now fully supports 120fps.
