In my in-depth Sony A7R VI review, I called it "the perfect camera"; but just how much better is it than its predecessor, the A7R V — and is it worth upgrading, or switching systems for, say from Canon and Nikon?
The previous A7R model launched in November 2022, so that makes three-and-a-half years between cameras, and gives me plenty to talk about. I'll cover the headline upgrades here, including the new sensor, design improvements and, notably, Sony’s first new battery for mirrorless cameras in nine years.
The answer to my 'upgrade or switch' question very much depends on what kind of photographer you are — so let’s dive straight into it…
1. Sensor
- A7R VI: 66.8MP stacked full-frame sensor
- A7R V: 61MP ‘standard’ full-frame sensor
- Canon and Nikon rivals have a 45MP stacked sensor
Sony’s ‘R’ nomenclature indicates resolution. If you buy an ‘R’ camera, you buy it for pixels — and lots of them — and images from both the A7R V and A7R VI are detail-rich.
With a stabilized 61MP full-frame sensor, the A7R V had the joint-most pixels in a full-frame camera, along with other Sony models including the A7C R and RX1R III, and some cameras from other brands, including Leica’s Q3 and the Sigma Fp L.
That 61MP sensor was debuted in the even older A7R IV, which is now seven years old (there's an updated A7R IVa still available for less than half the price of the A7R VI). Sony’s latest model has, however, upped the ante with a 66.8MP sensor, and it now leads the pack.
If it’s pixels alone that you’re concerned about, then that might seem like a small bump in resolution, especially when Sony rumors have regularly speculated about a 100MP sensor. A quick look at various Sony forums following the A7R VI's announcement makes it clear that some would-be upgraders are disappointed.
Is an extra 6MP worth upgrading for (read: spending a whole load more cash on)? On the surface, no. However, there’s more to a sensor than its pixels. The new sensor here is a ‘stacked’ type, which means it has a much faster readout speed, making it more capable for capturing fast-moving action and for video recording, with less rolling shutter distortion.
The A7R VI does, therefore, have the highest-resolution full-frame sensor, and it’s a speedy stacked type. It has stepped out of the ‘R’ series lane which prioritized quality, and into the speed and quality category occupied by Sony’s 50MP A1 II, which is slightly faster again but has less pixels.
In my book, the A7R VI’s sensor is the perfect marriage of speed and quality, and it's narrowed the market for the pricier A1 series to top sports photography pros. For everyone else, the A7R VI doesn’t miss a beat.
As for Sony and Canon rivals, their top cameras for detailed images include the Nikon Z8 and Canon EOS R5 Mark II, and those cameras max out at 45MP (as does the Lumix S1R II). Canon has a neat in-camera upscaling trick which quadruples resolution for pictures you’ve already captured to 180MP, but this is achieved by smart (and convincing I must add) upscaling.
2. Performance
- A7R VI: a stacked sensor and new Bionz XR 2 processor / combined AI chip
- A7R V: a regular sensor, Bionz XR processor and twin processor / AI chips
- Canon and Nikon rivals also feature a stacked sensor
The A7R VI’s stacked sensor has a faster readout speed than the A7R V, but Sony says the A1 II is even faster. Until lab testing is done, that’s as much detail as we have, because, unlike some other brands, Sony doesn’t divulge sensor readout-speed specifics.
A quicker sensor readout speed addresses rolling shutter distortion, making the A7R VI a better camera than its predecessor for video and fast-moving subjects when the electronic shutter is in play. Put simply, the A7R VI is more of an all-rounder than the A7R V, but there’s no advantage over the Nikon Z8 and Canon EOS R5 Mark II, which also have stacked sensors.
Following the lead of the Sony A7 V, the A7R VI has a combined Bionz XR 2 processor and AI chip, whereas in the A7R V the processor and AI chips are separate. Burst-shooting speeds are technically the same at 10fps using the mechanical shutter, and up to 30fps using the electronic shutter, but you should be able to squeeze out longer high-speed sequences with the mark VI versus its predecessor.
During my in-depth test of the A7R VI, I found that autofocus performance is marginally better too. It also adds an ‘auto’ subject-detection autofocus mode, meaning you don’t have to select a dedicated subject-detection mode, which is infinitely helpful when you’re regularly swapping between subject types.
The new processor and sensor combine for class-leading dynamic range, at least in theory, which is extended by one stop to 16 stops, with new dynamic range boost settings in the mix. Oh, and image stabilization performance has been marginally improved, measured at 8.5 stops to 8 stops (center) or up to 7 stops (periphery).
3. Battery
- A7R VI: New NP-SA100 battery with 2,670mAh capacity
- A7R V: The NP-FZ100 battery with 2,280mAh capacity
- Canon and Nikon rivals can't match the A7R VI’s battery life
Sony has introduced a completely new battery — the NP-SA100, which is physically bigger than the NP-FZ100 battery used in all of Sony’s full-frame mirrorless cameras for the last nine years. That battery was already legendary, delivering rival-beating capacity, and compatibility with a range of third party accessories such as external monitors.
The new battery is even better. How much better? It has 17% extra capacity at 2,670mAh compared to 2,280mAh. Battery life is one area where the A7R VI beats its predecessor, and indeed its rivals.
The bad news for existing Sony shooters is that the new battery is a different fit and physically larger, meaning there’s no forward or backwards compatibility with the older NP-FZ100 battery. If you’re looking at the A7R VI, your NP-FZ100 batteries are of no use, and additional batteries are going to be an extra cost to factor in.
4. Handling
- A7R VI: larger grip, illuminated buttons, brighter viewfinder, but otherwise much the same
- Both cameras feature a 3.2-inch 4-way vari-angle display and 9.44m-dot viewfinder
The larger battery is housed inside the camera’s grip, which is in turn physically larger than the one in the A7R V. I’m a fan of the larger grip, it’s even more comfortable to hold. Otherwise, the camera’s design is pretty similar to that of the A7R V’s — it’s a game of spot the difference.
Playing that game, I’ve found a few welcome tweaks. There’s a new lamp button on the top plate. Press it, and the control buttons around the body light up. I love this feature for low-light shooting, which makes locating buttons all the easier.
Speaking of lights, there’s also a tally lamp on the A7R VI, which is a handy visual aid letting you know the camera is recording, whereas the A7R V doesn't have one.
The displays are mostly the same. The 3.2-inch 2.1m-dot touchscreen has a four-way tilt hinge — you can tilt it up from the body, or pull it out to the side and rotate it for selfies, for vertical and horizontal shooting at just about any angle. The EVF is again a 9.44m-dot unit, but on the A7R VI it's 3x brighter, and I can attest that it’s an even nicer viewfinder to use — the best I’ve used on a camera this size, and up there with the very best of any camera I’ve used.
On the side of the new camera, each port has its own rigid door now, whereas some share a door in the A7R V. By the way, I much prefer this type of door to the soft doors found in most other cameras, which can get in the way.
5. Price
- A7R VI: Body-only: £4,500
- A7R V: Now £3,000 (launched at £4,000) while the A1 II is £6,200
- Nikon Z8: Now £3,000 (launched at £4,000)
- Canon EOS R5 Mark II: £4,500
Compared to the A7R V, the A7R VI is a pricier upgrade, especially since the A7R V is over three years old, and its price has dropped by about 25%. It started out at £4,000, but can now be had from Sony’s site and other leading retailers for around £3,000.
I’m not surprised by the bump in price, considering the time between the two cameras and the A7R VI's new sensor and battery.
The A1 II is much pricier than either, costing around £6,000, and making the A7R VI look like excellent value by comparison. That being said, Sony’s latest ‘R’ camera costs the same as the Canon EOS R5 Mark II, and is in turn pricier than the Nikon Z8 which is closer in price to the A7R V.
In summary, the A7R V costs significantly less, but the A7R VI gives you more camera, and offers decent value compared to rival models.
Conclusion
I already loved the Sony A7R V, with its 61MP full-frame sensor and speedy autofocus. The A7R VI is, however, better on both the quality and speed fronts, and even plants a foot on A1-series turf.
For me, as someone who shoots a wide range of photography genres, covering anything from landscapes to portraits and sports, the A7R VI is a dream camera, and it now tops my Sony camera wishlist.
Before the A7R VI was announced, I would have opted for Canon and Nikon rivals, given the various compromises in its predecessor, but the A7R VI changes the equation. It's a strong upgrade for a range of photo and video subjects, and could even be worth switching systems for. It also offers superior battery life, and a range of lenses for all budgets that Canon and Nikon owners wish they had. For me, the A7R VI is the professional camera to beat.
