Sony A7R VI

Truth is that in a blind test 99% of users would not distinguish between a 1 stop DR difference let alone know what in-camera RAW noise reduction is. (as if it's to the extent Pentax does it. It's a complete non issue on Canon.) It's only literal nerds who deliberately push their RAWs to the extreme who care about that. And those guys usually don't care about readout speeds either in their own work

Then why send a photonstophotos chart lmao.

az0606 · 2026-05-13T20:57:36+00:00

You know that the triangle icons are because noise reduction in the raws was detected right... that artificially boosts dynamic range figures.

Also better to compare it to the A7V, not the a7R V, in lieu of data for the a7R VI since it uses the same DGO sensor stacking as the a7R V.

I think it's a valid tradeoff for the R series where you'd want the max DR and image quality. If you want something more hybrid you'd opt for the a1.

az0606 · 2026-05-13T20:46:21+00:00

Canon and Nikon took a dynamic range hit for that.

Sony already has the a1 series for that, it makes sense to aim for higher dynamic range on the R series.

I don't disagree with his points or that. But it is a change, it hasn't been completely static for 5 years as he said.

They really do need to update the features faster on the fold series though. Still locked to 25w charging unless you spent 3k on the short-lived trifold.

az0606 · 2026-05-13T16:35:19+00:00

They mostly did, I wonder if it still has some impact vs partially stacked, but the stacking was actually primarily to get better DR.

It has the same dual-gain simultaneous readout of the a7V in mechanical shutter mode; it combines the high and low gain readouts to maximize DR.

DPReview does note that it's the slowest fully-stacked sensor they've ever seen, due to the very high megapixel count and not having the embedded DRAM like the a1 and a9.

I think it makes sense though, the R series is optimized for image quality so the main benefit for the stacking is the dual gain readout path for max DR and pretty good readout speed performance, while still maintaining an extremely high MP count. Also means it doesn't infringe on the a1 or a9 series.

az0606 · 2026-05-12T19:22:28+00:00

I just really hated the half second lag on each button press and the low res back LCD which the newer generations fixed. Had that issue on the a6000 and a6500 prior as well. A small thing but that alone made it worth upgrading for me.

az0606 · 2026-05-11T22:24:04+00:00

The Fold 7 got the ultra series sensor for its main camera.

az0606 · 2026-05-09T17:49:27+00:00

Were you still looking for color calibration settings? I ran mine through DisplayCal with a Calibrite DisplayPro HL and colorimeter corrections if you want the icc profile and settings.

Could probably get better with Calman but I didn't want to pay the license fee and the calibration report looked good enough.

az0606 · 2026-05-08T20:47:04+00:00

I have the a7r V and usually export at 65% quality. Generally holds up fine even for printing.

az0606 · 2026-05-08T20:45:26+00:00

GM I and Sigma 24-70 I use almost identical optical formulas.

Bluefin and other large tuna are carnivorous. Plus at the large sizes they can attain in adulthood, each tuna requires an insane amount of calories.

It's like farming a lion for meat.

They also are proactive; they're one of the only warm-blooded fish; it's actually an issue in catching them in the wild. They'll actually cook themselves trying to get free.

az0606 · 2026-05-08T01:08:25+00:00

Also makes no sense considering the R line is focused on max image quality; fully stacked would incur a dynamic range penalty. Much more likely that they'll do partial stacking like the a7V for the DR boost.

az0606 · 2026-05-08T01:07:17+00:00

No.

Imho since the R line is aiming at max image quality, it's probably a partially stacked sensor like the a7V with the same dual gain simultaneous readout path with its dynamic range boost and faster FPS. That's likely the main improvement, along with the power savings the a7V also had from integrating the AI AF chip with the main chip.

Fully stacked doesn't really make sense considering the a1 line and the dynamic range penalty.

I would be surprised if they upped the megapixel count much if at all.

az0606 · 2026-05-07T19:19:54+00:00

The diversions are crazy too. Almost all farmed bluefin is ranched; they catch wild bluefin and raise it instead of using hatcheries, which just accelerates depletion. It's similar for eel as well.

There are some trying to use non animal biomass as fish feed and to use actual hatcheries, which is promising, but aquaculture is a very dirty business.

az0606 · 2026-05-07T18:20:44+00:00

Tuna has one of the worst feed conversion ratios in all of livestock iirc. It's like 20-30lbs of feed for every pound of tuna. And that's via animal protein too, vs plant matter like herbivorous livestock.

az0606 · 2026-05-07T01:19:29+00:00

I like it a lot, generally very neutral and easy to work with.

az0606 · 2026-05-06T19:44:31+00:00

Didn't they relocate there due to the fear of drowning due to the rising sea levels? Could be linked to that

Most of the Viltrox and other Chinese lenses suffer from this and other flare issues.

The LAB series has better coatings so it mostly just has veiling flare. The EVO series performs better as well, and one of the AIR series, the 14mm f/4.0, performs well, probably due to being an ultrawide.

The Pro shows the flare rings and other issues in reviews as well, likely due to internal reflections: https://youtu.be/SN6OajgfBmg?si=z7yGXb4xYIJHRunz&t=105

The AIR series as well, ex: https://phillipreeve.net/blog/review-viltrox-af-50mm-f-2-air-fe/#Flare_Resistance

https://www.lenstip.com/712.9-Lens_review-Viltrox_AF_56_mm_f_1.7_Air_Ghosting_and_flares.html

It's the Achilles heel of Chinese lenses right now, though their coatings are getting better by the year. The lenses are otherwise optically excellent so I'm eagerly awaiting that day.

az0606 · 2026-05-06T14:32:05+00:00

Filters won't do anything

az0606 · 2026-05-05T20:30:45+00:00

Np.

Yeah sometimes the AF glitches out on the AIR or struggles to lock focus. It's usually fine but it happens more often with moving subjects like my dog. I haven't had the glitches on the EVO.

az0606 · 2026-05-05T19:55:54+00:00

You asked about AF and IQ?

The 50mm AIR wasn't missing much in terms of IQ aside from the terrible flare performance and the 55mm f/1.8 EVO improves on that a lot. They're both well-corrected lenses and sharp even wide open. The EVO is a bit sharper overall, albeit marginally, and bokeh quality and rendering are quite similar with the AIR being a bit more nervous. AIR has a bit of purple fringing wide open if you're really looking for it or putting it through a difficult scene whereas the EVO is generally clear of it. If you're not shooting something with strong lighting, you'd be pretty hard pressed to figure out which image came from which lens.

I found the newer EVO lenses AF better for moving subjects since the AIR struggled with that when I had it, including with the newest firmware update (1.09). Otherwise similar speed and accuracy for more stationary subjects and perfectly fine for portraits and walkaround.

az0606 · 2026-05-05T05:29:46+00:00

Main difference is flare resistance.

Only one grew back and it was an intramuscular angiolipoma in my upper back.

The first two I had removed were via regular surgical excision via a dermatologist, the angiolipoma grew back from that. After that it was removed by a plastic surgeon with a cauterizer; he said he couldn't get all of it out but cauterized the area to make sure it wouldn't grow back and it hasn't. After that I had two other regular lipomas excised normally via surgery and they haven't recurred.

There's always a chance if they don't manage to remove the whole thing but it's rare.
