On article Sony a7R III added to studio scene comparison (453 comments in total)

lensberg: The Sony A7 III .... The undisputed king of kings.

If the D850 was supposedly putting in a medium format equalling performance - This beast just trounces the competition. Always knew this sensor was superior to the D850's sensor.

Just waiting for Canon's response.

You can't compare sensor sharpness without taking lenses out of the equation first. At best, you can compare sensor noise.

Here the mkIII seems similar to the mkII, minus maybe shadow noise in low light, where it's now approaching A7S II levels:

Sdaniella: using just limited reference exemplar:

"best IQ resolution at base unboosted ISO" jpegs straight ooc is not adequate
nor
"best DR at base unboosted ISO" raw pp to fix-it-afterwards is not adequate

there are other reference exemplars that matter to far more endusers
and that is "practical immediacy" of:
"best IQ resolution at progressively higher ISOs as light progressively diminishes"
until
"any+all undesireable digital artifacts spoiling IQ resolution become unacceptable"
more so jpegs ooc, than "fix-it-too-late" raw

with the latter "practical immediacy" reference exemplar
i've been using 20mp+ FF Canon EOS 6D ISO 12,800 as my "acceptable minimum norm"

any+all others must exceed it, 20mp or higher, ISO 12,800 or higher, jpeg first, raw always second, and CLEAN UPSCALABILITY (NO downscaling shenanigans), in order to gain my due attention
otherwise, failing my minimum "reference norm" requirements, the other candidates instantly drop from any consideration

So your "reference" tells us that you like mushy detail from noise reduction, even in higher contrast areas and at base ISO (green detail gets destroyed at all ISO's) and thick Canon sharpening halos.

Someone had to translate that to make it readable. ;-)

janist74: My Galaxy S8 has no such issues....

@Capi:

No they don't. You have 4 profiles to choose from, one accurately matching sRGB, one Adobe RGB, one DCI P3 and one that is indeed oversaturated, exploiting the full capabilities of the OLED gamut at the cost of accuracy.

But even if you choose the latter, when you for example display supported HDR video material, the phone still switches to the calibrated P3 profile, unless you manually override it with a software switch.

This myth was put to bed many years ago when the choice for calibrated profiles was made available.

In reply to:

supeyugin1: IPhone is copying Samsung now: bezel-less design, and both lenses have OIS now. Also the screen size, wireless charging, finally an AMOLED screen and Gorilla Glass. Everything is like 3 years late to the game. The only things left are USB-C, headphone jack and SD card slot. Dual SIM will also help. Switch to Android, and you gonna be OK second tier phone like LG or HTC. Bravo Apple, you're getting there!

It's clear that someone in here hasn't used a Samsung phone in years. Their calibration is top notch when using the right profile (sRGB, Adobe RGB or DCI P3) and they have been well calibrated for at least 3 years. Their white balance has been closer to 6500K than Apple's (too blue) for years too.

And no the X is not closer to being bezelless, even if fake renders want to make you believe so. The actual bezels are 3 times thicker all around than the promotional material shows. Which leads to a smaller screen to body ratio than say an S8 or Note 8. Simple math.

In reply to:

LiangMing: The low light IQ is exceptional. At ISO 3200 and below, the picture shows excellent quality, compared to ISO at 1000 for D850, and ISO at 2000 for 5D IV.

It's still better at preserving detail than its competitors, especially low contrast detail. And better at avoiding horrible sharpening halos (hello Canon).

In reply to:

Richard Kwon: I returned my new D850 this morning. I am going to convert completely over to Sony with the a7riii. I was very worried with the D850 lack of IBIS. I had an a7r and lots of my photos were blurred. The a7rii's IBIS took cared of that problem. That is why I did not open my D850 box, because I was worried it will do the same with no IBIS.

Not saying the OP is one of them or passing judgment, but there are 100's of millions of people with shaky hands out there, either because of aging effects or medical reasons. My dad is one of those and even at wider angles, stabilization benefits him a lot. Which is not to say he can't shoot good images without it ever, but his hit rate for sharp shots increases dramatically with it, especially in less than ideal conditions.

In reply to:

bartjeej: I think in the comparisons to the 1" sensor group, it's useful to remember that the lens speed equivalence does a good job of comparing dof across sensor formats, and gives a good indication of low light potential (which also depends on sensor efficiency, besides equivalent aperture)... but in good light, where you can be at base iso regardless of the lens speed, the difference in f-number is made up for by the shutter speed. So long as thats the case, the larger sensor will still collect more photons than the smaller, giving potential for better dynamic range and color depth.

In theory, ceteris (such as efficiency per unit sensor area) paribus, yes.

But the smaller sensor is probably a little more efficient per area too. The R100 mk V scores the same maximum DR as the M5 for example despite a 3 times smaller sensor. In terms of color depth, the APS-C sensor does score a little better still.

Lee Jay: Oh, heck yeah!

We shouldn't just get away from light pollution, we should reduce it. Look to Flagstaff, AZ for a guide.

And in fact, a lot of the street lighting does not help in any meaningful way:
http://cs.astronomy.com/asy/b/astronomy/archive/2015/07/29/humans-cling-to-their-primal-fear-of-the-dark.aspx

It does indeed affect organisms all around the world, in negative ways. That includes humans, as pointed out by Lee Jay.

In reply to:

Iuvenis: Some of these look quite good, but some are terrible. That last shot of the mountain is so mushy, for example.

Noise seems to be a factor in all the shots. Why not shoot at ISO 25? If base ISO is 50, they're really missing a trick.

The last one used digital zoom, as did a few others.

In reply to:

Rigucci: At the resolution that the images are posted any of the decent phone cameras produces those images unless the images are posted for viewing the original file on a computer it is hard to determine whether the images are of good quality.

No, not every phone will do as well with large dynamic range scenes and subject isolation. In fact, barely any other phone does.

In reply to:

Cheng Bao: Most of them are very good.
However, why #20 and #27 looked like heavy processed by water color filter @iso50?

They appear to be using digital zoom (27mm equiv. cropped and upsampled to mimic a longer FL).

Jake2046: From my experience with all smartphones...most outdoor photography look great...BUT once you are indoor the images quality diminished dramatically.

Some of the outdoor shots appear to have used digital zoom though (for example the very last one).

It's quite a bit better thanks to fast and smart multi frame processing.

No, not in this sense.

The reason Red cameras are never compared, is because they apply temporal NR to still images, similar to taking several consecutive shots on a still camera and combining them.

JeanPierre Thibaudeau: The Sony A7R seems to have an edge over the D850 in the high ISO performance. Maybe the sharpness of the D850 is lower by default... Hard to say.

Color noise, ...hmmm, different eyes, different interpretations:

Lol

The less than 1 stop advantage is specifically in low light or noise in midtones/highlights, because in terms of DR we're probably looking at roughly 2 stops difference (S-LOG to take advantage of it).

On article iPhone X vs. Samsung Note 8 (380 comments in total)

" It is smaller, but it's inarguably better in terms of color management. The iPhone X's wide gamut OLED is the most color accurate device on the market"

Nonsense. The Samsung displays have been accurately calibrated (choice between sRGB, Adobe RGB and/or even wider gamuts) since the Note 4, 3 years ago and held the crown in this department since. The Note 7 was the first to support HDR display, even for images. The Note 8 also supports an accurately calibrated DCI-P3 gamut (alongside sRGB and Adobe RGB). Even though Android in itself defaults to sRGB, apps (including galleries) can take advantage of larger gamuts, including DCI-P3.

This is the type of misinformation I'd expect to see on non technical sites.

cosinaphile: apple and samsung both make great phones ... for my needs the headphone jack and sd option are not sacrificable .... i found this interesting.....

http://nymag.com/selectall/2017/08/samsungs-note-8-headphone-jack-got-a-lot-of-applause.html

"vice-president Justin Denison came out to talk about...the Note 8. 64 GB storage, 256 with a microSD card. wireless charging. IP68 resistant.

But Denison saved the best . “Thanks to our partnership with Harman, the Note 8 will come with premium AKG headphones, tuned for a superior listening experience,”
he said. “But wait, there’s more. Guess what you can do with those earphones? That’s right: You can plug them into the standard earphone jack.”

And the crowd went wild.

People whistled. There may have been some whoos, perhaps even some hooting and hollering. In other words, one of

the biggest applause lines of Samsung’s hour-long presentation wasn’t because of any innovative new feature — it was its decision to not innovate."

You don't have to be. A good device gives you choice. Wireless is a choice on the Samsung. Wired still allows better quality (better DAC built in the phone than almost any wireless headphones, no measurable or audible loss in quality during transmission to the headphones) and no hassle with recharging (and eventually dying) batteries in wireless headphones.

Or when you don't want the wire limitations, you can connect a wireless set.

Wires still allow benefits in many situations too and for that reason, they are still all around us and will be for many years to come.
