They solved a marketing problem of not having a Sony "stacked sensor" that their competitors have Stacked is a pretty liberal term, which can mean adding an any additional layer to the sensor, in this case an amorphous "processing layer" that I've yet to see a compelling reason adds any utility or value to the camera. But I'll reserve final judgement until more details are hopefully released.


It seems kind of obvious to me that Sony wanted to crow about something more than a 6mp increase in the sensor. So, they did something to speed up the readout to about the level of the partially stacked sensors out there including their A7V, but not so much that it would be real competition for the A1 or the A9. Rolling shutter greatly reduced but certainly not eliminated when using the e-shutter.

But here's an observation/question. All the "shill-tubers" who were testing this camera are using the terminology no doubt supplied by Sony..."fully stacked sensor". Anyone care to define that? If the A1 uses dram in their stacked sensor and the A7RVI does not, then how is it "fully" stacked? If the rumors site is told by their informants that the new camera has a fully stacked sensor, then I'm not surprised they assumed it would have dram and be in the same ballpark as the A1 with regard to readout speed. I'm holding Sony responsible for the confusion, not the rumors site or anyone taken in by Sony marketing.

It's definitely your high-DPI display. It obscures both noise and detail issues.

Bill Claff has measured sample variations of sensors and found it to be very low:

Thank you for this link! I feel like I gotta deep dive and go down a rabbit hole now with the high DPI obscuring noise aspect, though. That's a new one for me.

$120 for an extra battery seems steep, but hopefully will provide extra capacity in the field. With the current Sony NP-FZ100 I always get a full day of landscape shooting out of one (usually 1.5 days), so I only carried one additional per camera as backup.

As noted elsewhere, the grip has been made a bit bigger to accommodate this slightly larger battery. In DPR’s review they noted:

"The new, larger battery, which sits longitudinally down the grip, rather than the transverse arrangement of the previous design, means the camera's grip has been reworked. It's a subtle change, but the lip around the top of the handgrip is slightly more prominent and the recess on the mount side of the grip, where your fingertips rest, has been reshaped.

Sony stressed that it's not the same as the a1 II/a9 III design (the shutter button isn't at nearly so steep an angle, for a start), but it seems more comfortable than even the recent a7 V's shape.

According to Richard Butler at Dpreview, "fully-stacked" vs "partially-stacked" is based on the size of the second semiconductor wafer that's bonded to the the image sensor, with fully-stack representing a wafer that's near-equal size of the sensor's wafer and partially-stack being a wafer smaller than the sensor's wafer, independent of what's on the second wafer (DRAM, additional logic, etc...)

Okay, but a full stacked layer for "...an amorphous "processing layer"... "? So, we don't know what's going on with that stacked layer, but we do know that it's not holding dram. I'll still contend that since other "fully stacked" sensors have dram in the stacked layer, this new one is different to the point of confusion from Sony not identifying that this stacked sensor was not typical of the genre.

I agree, it seems dubious but I'm reserving judgement until more details come out about what they put in that "processing layer". Dpreview hinted the logic on that layer is what achieves the DR improvement, which is plausible (but I'm very skeptical) because perhaps the extra parallel row readouts required to increase the readout speed (even without embedded DRAM) to support DGO may require more logic for a higher-density sensor like the A7RVI than it did for the partially-stack variants in their other sensors.

I empathize. At the same time, when comparing the A7RV and A1 II. I own both and ran controlled experiments myself, with consistent flash exposure, color targets and greyscale stepwedges. I see very little difference at ISO 6400 between them, and it evaporates entirely when I downsample the R image to 50MP to match the A1. Strangely it seems, my eyes do not agree with what you're saying. But you are not the only one noticing this, I wonder why.

I have two theories to explain it.

First, is that I am only using high-DPI displays, i.e. I am only seeing

You won't see any details at 100% and 220DPI, so you are fooling yourself about the noise and sharpness differences. You would need to zoom to 200% or view the display at very close distances.

Okay...I'm not arguing that Sony stuck an additional layer to the sensor just so they could call it fully stacked. It must have some purpose. My argument/complaint is that Sony is crowing about the sensor being fully stacked without explaining what the advantage is in this case...and it doesn't take a rocket scientist to conclude that most photographers hearing that the sensor was fully stacked would assume that means super-fast readout speed because that is what we associate with stacked sensors.

If the purpose of the stacking is to support DGO....then Sony should have emphasized that in their press release and presentations.

I tried it for 2 days but the ISO quality wasnt' great due to high resolution which is very noticable from ISO 400. Higher than 1000 will be quite noisy at 100% zoom.

The biggest problem is the diffraction limit starts from F/5. Yup, stopping down will only decrease the sharpness and overall quality which is expected for high megapiexls on FF sensors. While 100-400GM wasn't really sharp at wide open, both 70-200 and 50-150 at wide open were kinda sharp and great.

The body performance was great as expected. Nothing to explain.

The body design is quite identical to A7R5 or 4th gen which is very very disappointing. No ergonomic upgrades while no custom button on the front side. A huge downgrade from 5th gen or A9iii/A1ii. The battery grip sucks too.

You get a new light button on the top which will illuminate several back buttons. Kinda useful but it would've be nice if they also added a light in front of the body just like Pentax K-1.

A new battery has a different design which will never be compatible. The size is slightly bigger than NP-FZ100. Not sure if it's better as it also consumed a lot of power while shooting photos. At least it finally supports the battery health.

Still supports CFexpress 2.0 but the buffer or performance is a lot better. Can shoot 30 FPS for 7 sec with compressed RAW format and tested with slow SD cards. Might be a lot better with CFexpress Type A. Truly impressive and A1iii might actually could possibly shoot 60/120 FPS.

The stacked sensor is the biggest difference but with many limitations. Read out speed is slow so it can NOT replace A1ii instead of similar to A7V, no flash sync with e-shutter which is huge bummer, 1/8000 is max, no anti-flicker on e-shutter, and more. I guess the buffer is the only main upgrade which I can shoot for 7 sec with compressed RAW + SD cards.

LCD and viewfinder quality are now great. But the viewfinder size is still small compared to Canon and Nikon so kinda bummer.

You're fooling yourself by looking at a photograph at 200%. You're literally asking the software to create pixels that do not exist so you can get angry at them. Why do you choose to live a life like that?

On a hi-res monitor you can change resolution. Integral multiples like 200% don't require any interpolation like 150% does. So your 5K display can be switched to 2K (2.5K, 2560x). So the display at 5120 will show the same size of pixel at 10 inches viewing distance as the 2560 will at 20 inches viewing distance. Of course that mode would not be used for regular viewing, but it makes sense to analyze critical image attributes. A 66 MP camera is not needed to look at an entire image at once; that only needs around 8MP.

Does anyone know what kind of A-S base plate will fit the a7rVI bottom? I have the small-rig one that adds about 1cm all around to allow for the 5th digit to get a grip on the a7rV hand held.
I suppose it must be a new design to accommodate the larger battery.

Which part of "5x faster readout than its predecessor" are you struggling to understand ? It's hardly Sony's fault that you and a few others got a bit over excited thinking it would be as fast as or faster than an A1.

And as for it must have a purpose - to quote Jan Wegener:

“If you are after breathtaking resolution, extraordinary cropping capability, and the added bonus of a genuine action camera all in one body then the A7r6 delivers like nothing else on the market”

Nope. LCD pixel grid is static. What you're changing is software settings to create or destroy pixels to create an illusion of more/less resolution. If you want to learn how to use computers, just ask. Don't guess.

What critical image attributes can be seen in a 200% zoomed image that can't be seen at 100% ?

This is beyond the thread, but my point is that if you cannot see the pixels then your eye is just averaging out the noise and not differentiating the resolution at some point.

Yes, i'm not explaining it right.
Can't you use Xrandr or something to just double up on pixels or use what they called integer scaling in other OS to avoid interpolation? I'm normally at 100% with two displays, one for editing and one for viewing, but I used to do it.
I also had the high diopter bifocals to view prints from 20cm (10 inches). Some called it pixel peepers.
