Finally I can say with 95% confidence that the Sony A7V coming on December 2 will feature a BRAND NEW 33MP partially stacked sensor! Let’s get into the details:

This is the world’s highest resolution 33mp partially stacked sensor!

The Nikon Z6III and Panasonic Lumix S1II both use a Sony-made 24MP partially stacked sensor. Sony is now set to become the first to offer a higher-resolution version of this sensor technology. In contrast, the newly announced Canon R6III still uses a traditional non-stacked sensor.

It’s currently unclear whether Sony’s new sensor shares the same architectural foundation as the 24MP version used in the Nikon and Lumix models, or if it represents a new generation design. The existing 24MP partially stacked sensor has a known limitation in dynamic range performance. As demonstrated by Photons to Photos, the Nikon Z6III shows a drop in dynamic range at both base and mid ISO levels. Panasonic addressed this issue in the Lumix S1II by introducing a “DR ON/OFF” mode, allowing users to prioritize higher dynamic range at the expense of slower readout speeds. CineD tested this feature and noted:

Life is all about compromise; hence, this comes at a price. This would be the slow readout speed, resulting in 27.5ms rolling shutter for full-frame mode (with DR Boost “ON” – “OFF” yields a good 12.7ms) – the superb in-camera IBIS can, however, mitigate most of the negative rolling shutter effects for a lot of shooting scenarios.

It’s still unclear whether Sony’s new 33MP sensor will share the same dynamic range “limitation,” or if Sony plans to implement a DR ON/OFF mode similar to what Lumix offers.

30fps in electronic shutter mode:

The Sony A7V is capable of shooting at 30fps with the electronic shutter, while the Canon R6III pushes this further to 40fps—but only in 12-bit mode. At this point, it’s still unclear whether the A7V maintains full 14-bit image quality at 30fps. I’m currently working to confirm this detail through my sources.

10fps in mechanical shutter mode:

The Sony A7V retains the same 10fps mechanical shutter speed as the A7IV, while the Canon R6III edges ahead with 12fps. Interestingly, one of my sources claims Sony may have artificially limited this via software—the hardware could allegedly support up to 15fps. While this isn’t confirmed, it raises the possibility that Sony might unlock higher mechanical and electronic shutter speeds through future firmware updates, especially if the community pushes for it.

Finally: 4k60p with NO crop!

Finally, the Sony A7V can record 4K/60p with no crop—giving it an edge over the new Sony FX2 in this respect 😉

More specs coming soon:

These are the specs I can safely share for now. I’ve received additional details from one source, but I’m waiting for confirmation from others to avoid any mistakes. As always, the devil is in the details—raw specs alone don’t always reveal whether this camera will truly outperform the Canon R6III.

Sony A7V rumored specs :

• 33MP partially stacked sensor
• 30fps in electronic shutter and 10fps in mechanical
• 8 stops IBIS
• 4k6’p no crop
• new AI chip like the Sony A1II
• Free-Angle Tilting 3.2″ Touchscreen LCD
• 2x dual Type A SD slot
• no C5 button
• improved EVF (5.6m dot?)
• dual USB-C port (gets rid of the micro-USB port)
• Same Sony A7rV body design.
• price close to $3000
• Announcement on December 2
• Limited batch ships before Christmas
• Sony A7V Preorders (open on Dec 2): BHphoto, Amazon.

What are your thoughts so far about this camera?

I personally think that while it might not beat the ass out of the Canon R6III…things like superior EVF, autofocus, Image Quality and overall lens availability will make this a hot seller!

It’s late night and I am totally exhausted. Right before jumping into my bed a THIRD source confirmed it: Sony A7V has a new 33MP sensor!

Now I have zero doubts left, and I’ll share detailed info within 24 hours. The fear of a lukewarm update is gone for good — this camera will stand toe-to-toe with, and possibly surpass, the Canon R6 III. Tell your Canon friends they might want to cancel their preorders. 😉

Good Night!
