MrDigital: WOW!!! another camera for grownup!!

Please children step aside with your toy bodies cameras and watch the grownups play.

This camera has a pro body, so is not for everybody. This is a real camera. The value this camera offer is unbelievable!! The cost of the Sony A1 + vertical grip will cost you $6974.49 at B&H!!!

“It’s 10PM, Do you know where your children are? Yes!!!, They’re playing with their toy bodies cameras!!!!

This is exactly the type of BS I would expect from a child.

nilsjohan: wow, lighter than the RF 70-200, and without being an airpump!

While retaining TC compatibility unlike the RF, that is a big win.

Larsskv: I found it interesting to compare the A1 against Canon 5DSr, a camera that was criticized here on DPR for it poor dynamic range: https://www.dpreview.com/reviews/image-comparison/fullscreen?attr134_0=canon_eosr5&attr134_1=canon_eos6d&attr134_2=canon_eos5dsr&attr134_3=sony_a1&attr134_4=canon_eos5dsr&attr134_5=sony_a1&attr136_0=3&attr136_1=3&attr136_2=3&attr136_3=3&attr136_4=4&attr136_5=4&attr176_0=efc&attr176_1=efc&attr176_2=efc&attr176_3=efc&attr176_4=efc&attr176_5=efc&normalization=full&widget=230&x=-0.03337784162009984&y=-0.05262690729281216

Since you deliberately choose examples that make Canon look as good as possible and Sony as bad as possible and conveniently do not post anything counter to that you only demonstrate your own bias. Where is your 5DSr high iso or 100iso examples?

The A1 has much better dynamic range than the 5DSr at both high and base ISO, it also has better high iso performance than that sensor. And that is with something like 50 times faster readout. It also does well against the R5 and soundly beats it with electronic shutter while having 5 times as fast readout as that camera as well.

Larsskv is a notorious Canon fan so he deliberately picks ISO 400 which is where the A1 performs worst as it is just below the conversion gain change at 500. An A1 shooter who is concerned about dynamic range does not shoot at 400, you pick either 100 or 500 for the optimal results.

A far more interesting comparison is this, it also shows e shutter performance which is one of the main benefits of mirrorless:

Lets not forget that the R5 results include baked in noise reduction in the raws to make it look better below 800 iso.

Larsskv: Is it just me, or is the R5 much better at ISO 6400 than the Sony? And what about invariance? Compare R5 at ISO 400 + 4 EV to the Sony, and the Canon smokes the Sony. How did DPreview overlook this?

As usual people see what they want to see using the comparison tool, usually by not normalizing image size.

Noise is however best compared analytically, not using a random raw development that is not identical between different cameras. Because that leaves it up to the company writing the raw developer to decide which one will look best.

But if you want to look another example, I wouldn't say the R5 looks less noisy here:

Larskv that is because Canon is baking in noise reduction into the raws below iso 800.

panther fan: A fantastic article. One smaller nitpick

"we use the R6 as a proxy here as the sensor measurements are identical"

I don't know if that is exactly fair. The R6 (and R5) only allow 12bit capture in electronic shutter mode, which hurts base ISO DR. I think the 1DX III might offer 14bit readout so results could be slightly different.

It matters in the sense that it shows that there are more than 12bit in the data before compression. Sony's compression algorithm is well known that it uses 11bit non linear compression that skips every odd value at the lowest end of the scale. It does not rule out that there was 14bit before compression. But that wouldn't matter either since the 14th bit is lost in the compression anyways.

Craw is max 13bit as Jim says and after checking Rawdigger histograms I can confirm that the 30FPS craw files from the A1 got 13 bits of information in them.

In reply to:

Thoughts R Us: Both of these statements can be true at the same time:

The sensor in the a1 represents a great engineering achievement. Right now it is probably the most advanced FF sensor on the market.

While impressive, the type of gains the sensor gives are incremental improvements. We are at a stage of diminishing returns on large sensor technology without some breakthrough. In real world usage, images from the a1 will be very similar to others from the types of cameras compared against here.

Even the fast readout speed is a diminishing return. I saw one wildlife photographer note that if anyone says they need more than 20 fps they are doing something wrong. Another noted that 30 fps gives you too many images to cull from. And these are people who overall praised the a1.

Ultimately, the best testimony to any camera is that it enables images that otherwise would not be captured. That's what I want to see. Images take with the a1 not possible with other FF cameras.

The whole premise is flawed: You can take any picture with any camera, just move the focus distance to the right distance and shoot at the right time. Might take a million tries with some ancient camera however....

In reply to:

PNad: I’m not sure what impress me more, the fact that the A1 can shoot electronically with absolutely not penalty (full 14bit readout, no perceived increased noise) and even sync with flash, it literally could have been released without a mechanical shutter

Or the fact that half the comments totally ignores it and think a Canon R5 is a cheaper A1.

That mechanical shutter from a decade ago shoots 30fps? Is it silent? Does it wear out from use? Does it cause camera shake?

The R5 is cheaper but it also has a long list of drawbacks:
- Bad rolling shutter performance in electronic mode
- Big dynamic range loss in electronic mode
- Banding when shooting electronic with fast shutter speeds in artificial light
- Only can do 12FPS mechanical while battery is close to full
- No blackout free shooting, harder to follow fast action
- Overheats and has extremely long cool down time when recording video above 4k 30p
- Slower flash synch in mechanical / no flash synch in electronic
- Baked in noise reduction in raw below 800 ISO

If none of those issues bother you then it's a great buy.

Funny Valentine: All the mental gymnastics they go though to avoid any question about the size of the e-mount and tubes attached on the back of every sony lens. It's time to answer this question once and for all.

When a camera company's best argument for why you should buy their gear is the diameter of the mount then you know they are in trouble!

In reply to:

Fotoni: Why even thinking about more complex global shutter, if A1 electronic rolling shutter is almost as fast as most mechanical shutters? The gap is shrinking rapidly and next improvement will make mechanical obsolete. I just hope that Sony did not compromise dynamic range or something when using that new fast electronic shutter.

Computational photography could help pixel shift and photo stacking to achieve more convincing results when there is too much motion. Phone photos can be very noisy in the first place, but when there are cameras which produce already quite sharp and clean results with a single photo, imagine what could be calculated from a 16 photo pixel shift stack? That is a quite big chunk of reality to refer when doing motion compensation.

But computational photography can be a software you download. No need to torture camera hardware with things which can be done better with much more powerful personal computer. Maybe next version of Rawtherapee or Darktable?

If a global shutter comes at a cost in low light performance or dynamic range, then I prefer a good rolling shutter like in the A1.

JasonTheBirder: One question I liked was whether they received any requests for computational photography features from the top photographers along the lines of smartphones. To be honest I cannot think of a single real-world scenario where computational photography would be useful at all, especially with regard to the use cases of this camera. And you know what, Oshima confirmed it with the answer: "No".

Agree with Cheng Bao, pro capture is not computational photography. It is just shooting bursts while half pressing shutter button and keeping a number of the most recent frames in a ring buffer and only saving them to card when the button is fully pressed. Definitely a feature I would want though. Perhaps they could add it with firmware unless there are some sensor thermal considerations preventing it.

In reply to:

RadPhoto: For Sony fans, and all of a sudden, image quality and better high iso performance are not important as having an XLR port!

They’re grasping at straws for trying to justify the super-high price for the value.

The A1 is a little bit more than a R5 competitor. It is a tool professionals can rely on in any conditions. It gives you a full uninterrupted 60+ frames view while shooting bursts, delivers max performance in artificial light without banding, fast panning action without skewed backgrounds, swinging baseball bats and golf clubs not looking bent. And it performs fully whether the battery is at 90% charge or if it is at 10% charge. It can also do video without atrocious downtime of the R5.

The R5 is a great spec sheet. Great for amateurs which can live with its limitations. As for competition to the A1 we will have to wait for the R1.

On article Sony a7S III review (2787 comments in total)
In reply to:

(unknown member): "Of course it's much less detailed than the 2X oversampled footage from the Canon EOS R5 (4K from 8K capture)"
I was hoping to see some comments of how the A7Siii video compared to the A7iii and S5 other 24MP cameras that oversample, or even the A6600 or X-T4. Would you say it is less detailed than those ?
When I compare the default image in the video scene (the circle and text) to the A7iii, the A7iii appears to have more detail and less moire. So is it not fair to say the A7iii for many provides better 4K video, especially if heavy post processing is not the goal?

Also, in the past the A7S was the king of low light, but here it says,
"You need to be working at extremes for the slight shadow noise benefit over the Z6 II's 24MP sensor to appear, and even then the lower resolution of the a7S III is still visible."
So with the more detail at all ISOs and very little benefit at 'extremes', have the 20-24MP FF cameras caught up?

They are far from catching up if you want 4k 60FPS or 120FPS from a (near) full sensor readout.

richard cohen: I'm a nikon shooter who is also experimenting with an R5. I've tried an A9 a couple of times and never warmed to it. However, this Alpha 1 sounds basically perfect...if anything, more performance than I would want in a camera. It doesn't compare with the R5, it is in a completely different price class. The specs sound very similar to the rumors of the Nikon pro body mirrorless coming out later this year. I hope so, not that I can afford any of these pro bodies. But good for sony for being the first out there. I'm sure nikon and canon will follow.

All cameras have rolling shutter, who said otherwise? The A1 does a full readout in less than 1/200s (comparable to a mechanical shutter) while the R5 is 1/50? At least a factor of 4 difference.
Banding is solved 2 ways in the A1 by timing the exposure to when the light source is at it's brightest and most stable to avoid banding with 100 or 120hz light sources just like the cameras with mechanical shutter do. But it can also fine adjust shutter speed to match other types of light sources which other cameras can't except A9II.
The R5 doesn't do flash with electronic shutter afaik, if it does it would at most be able to do it at 1/50s as it can't be faster than shutter scan time.
And the R5 does drop to 12bit (or maybe even 11) at 20fps electronic. This has been analyzed by Bill Claff, find his thread on the subject on the Canon forum.

People may fall to the trap of comparing A1 and R5 on basis of the spec sheet alone but that is misleading. The R5 suffer from many of the child diseases of electronic shutter: banding, rolling shutter, no flash synch, 12bit. The A1 fixes all of that (except 12bit @30fps but the R5 doesn't offer that at all). The A1 is the first camera which can do basically everything in electronic mode, they could have taken out the mechanical shutter for all I care.

Sonny Camera: I think all of us interested in buying a new camera are in agreement. We would rather have seen an A7R5. This is not something the Sony user base cannot afford or wants to pay for.
Give us an A7R5 or A74. Everyone is back to wishing and dreaming for cameras that may not be coming for awhile. Or like the A7000 and A99iii, ever.

We are not, I'm getting this and am not interested in A7R5.

Aleks7: How fast and how long does it shoot into real RAW?

If I was a Canon troll the last thing I would want to bring attention too is bit depth. The R5 drops to 12bit in 12FPS mode and 11bit in e-shutter. Even with the baked in NR below ISO 640 (which means lost data by the way) it falls below the A9II in DR.
