sh10453: Nice to know that Sony has now made a sensible menu, and the user is no longer feeling lost. So this will no doubt percolate to other Sony cameras.

If the durability and weather sealing are not there, or not even close to the 1DX / D5, I am not sure who the target is for this very expensive camera.

Entoman - I do not believe it's the case that Sony semiconductor only sells older chips to other cameras companies. We've seen new chips turn up in other brand's cameras before Sony fairly regularly. Furthermore, it would be bad business for Sony's Semiconductor business if its clients thought they were getting second-rate products or unfair treatment (this has always been the line from Sony).

In a recent interview with IR, Sony seemed to say that its camera team sometimes commissions chips that include their own IP and it's these that only Sony cameras have. But, in principle, other customers could do the same. That's my understanding, anyway.

weixing: I'm sure think there will be someone out there that will open up a 5D4 and check what's the difference between a 5D4 with and without the C-Log upgrade... :-P

Their statement is: 'Due to the software architecture in the camera we need to connect and use our service tool to upgrade.'

Canon has just made a 'clarification.' There is no hardware change.

CreeDo: no video expert but does this mean a different codec to record this higher-dynamic-range video?

From my understanding, canon video uses an ancient inefficient mjpeg codec that creates monster filesizes, like 4 gigs per minute at full res. Basically each frame is a full jpeg file.

So if this is the video equivalent of raw vs. jpeg, does that mean these already huge filesizes will get like 10x bigger? Can this format record that extra data, when you consider the fact that a jpg still can't hold all the highlight and shadow data in a raw still?

Log gamma absolutely isn't the equivalent of Raw vs JPEG, it's the equivalent of shooting the lowest-possible contrast image to squeeze everything you can into the confines of a JPEG specifically because you can't shoot Raw.

So, while it being an 8-bit file is a limitation, the use of a format that retains more information than usual might actually be a slight benefit in this instance.

In reply to:

davids8560: The Canon G9X MARK II is clearly the winner at the moment if SMALLEST SIZE/BEST POSSIBLE IQ are the *sole* parameters.

(Those aren't the sole parameters for me, however)

But ask me again tomorrow, by all means!

Whether G9X II gives the best possible IQ depends on where in the lens range you are. It's significantly slower at the long end of the zoom, which will have a significant impact on IQ in situations where you're light limited.

I've added it to the graph on page 1, to demonstrate this.

Tom Marshall: Just wondering how many have noticed this 'accessory' is listed at $399.99 USD at B&H.

That's interesting: I'll add it to the story.

On article Canon PowerShot G7 X Review (488 comments in total)
In reply to:

Truculent: Quite a sell job in favour of the newer G7X over the G1X II. And the comments are inaccurate. If the G1X II sensor was twice as big it would be a 2 inch sensor not a 1.5 inch sensor. And the only reason the G7x's noise is close to the G1X at high ISO is because they smear all the details to achieve this. Very bias and misinforming for those choosing between the two cameras. I thought this site knew better, very disappointed.

The noise (even in Raw) is [very close](https://www.dxomark.com/Cameras/Compare/Side-by-side/Canon-PowerShot-G7-X-versus-Canon-PowerShot-G1-X-Mark-II___978_941) to that of the G1X II because it has a more modern, more efficient sensor. When you also take into account the faster lens on the G7 X, you should find it's possible to get *better* low light images with the G7 X, despite the smaller sensor.

The "inch type" system doesn't refer to a measurement of the sensor, it's an obscure naming system [based on vidicon tubes](https://www.dpreview.com/articles/8095816568/sensorsizes).

However, it's related to the diagonal of the sensor, so you don't need to double the number to end up with a sensor twice the size.

On article Nikon D7500 vs Nikon D500: Which is better for you? (387 comments in total)
In reply to:

iceman003: Will the D7500 work(by work I mean focusing and metering) with http://imaging.nikon.com/lineup/lens/zoom/normalzoom/af-s_dx_16-85mmf_35-56g_vr/index.htm and http://imaging.nikon.com/lineup/lens/singlefocal/normal/af-s_50mmf_18g/index.htm ?

Yes, in both cases.

It's only the old AI type lenses that the D7500 no longer supports.

Magnar W: To the Dpreview staff:
Please do some torture tracking autofocus tests as soon as possible! Fast action, erratic movements, low light action, you name it! We will accept the results, even if the speed and precision is not quite up to our expectations! ;-)

Oh we will, as soon as we get a chance.

tonywong: Any word on whether it will charge a NP-FW50 battery as well? It would be ideal for anyone who carries both an A7 and an A9 to only require one charger to charge up the fleet of batteries for the day.

Sony's [product page](http://www.sony.com/electronics/interchangeable-lens-cameras-batteries-chargers/npa-mqz1k#product_details_default) only mentions NP-FZ100s, though I believe it's sold with two batteries.

Zenza R: usb 2: does it mean we will be still waiting for reviewing images? (like in all a7 cameras)

Zenza R - it's not USB 2 that slows down Sonys: the vast majority of cameras still use USB 2 but don't have the slight delay that the a7 cameras have.

FOTONOTO: Does it support s-log3 and gamma display assist function?

Picture Profiles is absent, so there's no Log for Gamma Disp Asst to correct for.

Very odd.

In reply to:

FOTONOTO: Does it support s-log3 and gamma display assist function?

I've just heard back: it has been removed. Consider me surprised.

This is sad, since I'm being told the footage looks good and has very little rolling shutter.

It's XAVC S and, based on previous Alphas, it'll be 8-bit 4:2:0 internal and probably 8-bit 4:2:2 over HDMI.

I'll ask the guys in New York but I'd be surprised if they've taken that feature off.

sibuzaru: see, if they used USB-C 3.1 it wouldn't need a dummy battery to connect to the camera

But nor would it offer backwards compatibility.

QuarryCat: the best is...
I don't know one single lens I would like to have from Sony.
It is good for pushing Fujifilm, Canon and Nikon forward - but that's it.

No Pro service except the one they announced they were expanding today?

Mister Joseph: What a sexy Ethernet port!

Do you find the ones on the D5 an 1DX II just as funny?

It seems reasonable to assume it's been added because pro sports shooters use it.

Sorry, got that one wrong. That'll teach me for trying to respond while also reporting a launch.

Don Sata: Nice, is electronic shutter global?

No. It's still a progressive shutter but very fast (according to Sony), to reduce rolling shutter.
