Seems outstanding in low light:

Michael Ma: It seems to have an unusual amount of color artifacts in the raw files though.

Jpegs look fine but not sure if a raw converter will know how to handle this properly.

You need more mp if you want to properly resolve that part of the test scene, and without brutal aliasing.

peeyaj: Is my eye deceiving me? The A7III blows the A7rIII in high iso performance!! What sorcery is this?

Less read noise. The difference is definitely noticeable.

In reply to:

sfft: It seems all those stripes are due to sensor flare. Most of the MFT and Fuji shooters are aware of this issue. Deal-breaker for back - lit scene shooters, no probs for me.

However, in almost all of the captures the tones are pretty unpleasant. The color cast on the garments, skin tones etc. The environment seems pretty bad for such a test. Will be waiting for test shots which are done in properly lit environments to make a judgement.

@ssft - That's exactly what dpreview should test.

In all of the shots that show the issue, 85/1.8 lens is used and light is at the very edge of the frame. Put the light elsewhere in the frame, use the same lens. Does it still show? Does it show with a different lens? etc etc

In reply to:

Entropy512: Why is it that you stripped EXIF metadata from the two images that you say show issues with the camera?

Most of your images have EXIF data including shutter speed, but it is conspicuously missing from all images that show problematic behavior.

Of note, the problematic behavior looks somewhat indicative of banding in artificial light - possibly a high-frequency PWM dimming scheme?

Four pictures show the issue: number 5, 6, 15, 25. All have exif stripped.

Serious issue on what otherwise looks like a great camera. We've seen mild striping reports before on Sony cameras with on-sensor PDAF, but this looks bad to the point of ruining the image.

In reply to:

Pete_W: Gold, seriously? With no reasoning. Do you throw a dart at a dartboard and select the award level based on whatever you hit?

I don't see anything unusual about the high marks here despite the still performance and the price. Sony A7s is also a video-oriented camera, and it also got the gold award too, despite it's stills image quality. For GH5s, dpreview clearly states it produces the best video quality they ever tested.

Surely, gold award is completely warranted in this case?

Not a first, A7s got a gold award too. ;)

On article Buying Guide: The best pocketable enthusiast cameras (92 comments in total)

"Pocketable" is subjective. What pocket? Winter jacket? Shirt? Jeans? Whose pocket? Some of these cameras may fit in Yao Ming's pocket, but they won't fit in mine.

I think for future guides you should maybe consider specifying a certain size (for example: maximum size that fits easily into a jeans pocket of an average person), and anything larger should be eliminated.

Massive improvement at high ISO. Seems Sony's claims of reduced read noise are true.

Well done, Sony!

@Rishi - a question about high ISO. You said: "showing parity between high ISO a7R III and a9 performance". Doesn't this mean a noticeable (read noise) improvement over the A7r2 at high ISO? Dpreview's test scene shows A9 to have cleaner shadows at high ISO compared to A7r2.

Toselli: FE mount? We may suppose that A mount is going towards its retirement... Wouldn't be better to have made it A mount and including a free A-FE adapter even if the AF motor would have been optimized for mirrorless AF?

A-mount is alive, though on life support. Last A-mount lenses were announced 3 years ago, if I'm not mistaken.

In reply to:

MikeRan: All the comments previously about "Sony's not a pro sports camera. They don't have the lenses." And so many complains because most can't afford a pro sports lens. Comical...

Mike, while A9 is a sports camera, complaints about lenses were legitimate. They indeed didn't have (still don't, until next summer) the lenses. I'm sure this is just a start and they'll eventually come out with a 600/4 and 300/2.8, etc.

As for the price, no one should be surprised. There's no such thing as a cheap 400/2.8. Start saving.

Reilly Diefenbach: I sure wouldn't want a herkin 400 f 2.8 with a teeny little body on it. That would be very fatiguing.

Hey Reilly. This will be used on a monopod, with battery grip on A9. No one handholds monster lenses like 400/2.8 or 600/4.
