PhotoRotterdam: Digital medium format is really stepping into a new age. Very nice product by its description, looking forward to the detailed reviews (an photos!) that no doubt will appear.
Unfortunately way out of what I ever would allow myself to spend on photographic gear, but I understand the appeal of this for people who make a living out of photography.

Fingers crossed for Fuji to enter this market segment again.

I'm pretty sure Fuji are involved already - don't they make at least some of the lenses for this system?

TheDarmok74: Kudos to Huawei for what they have achieved in relatively little time.
They now release 2 high-end models a year like Apple or Samsung.
BUT no OIS in a high-end device? Even with better light sensitivity, I cannot imagine that I'd want to pass on OIS. I've been uising it since the Nexus 5 and it works really great on that phone and now on the Samsung S6 too.

They have been making phones longer than Apple. We used to have ~ 2004 vintage "smart" phones made by them and they were rock solid. Not that the Windows mobile operating system was any fun to use!

BigOne: Chinese crap at least used to be cheap. Not anymore.

Though it's also less crap than it was. Even iPhones are Chinese...

On article Nikon D5 real-world low light, high ISO samples (281 comments in total)
In reply to:

Michael Uschold: This is great low light performance, however the ISO numbers are painful to make any sense of.

POP QUIZ: How may stops bigger than ISO 102000 is ISO 3,280,000?

You have to keep count of how many times you have to multiply the smaller number by 2 till you get the larger number. This is what log scales are for, and we already have one, we just have to start using it. For example, 100 speed is written as ISO 100/21°, One stop faster is written ISO 200/24°. It goes up by 3 for each doubling in speed.

So for the above quiz, the math is much easier if the speeds are written as ISO 102000/51° and ISO 3,280,000/66°. SUbtract 51 from 66 to get 15, and divide by 3 to get 5 stops. Viola.

And you dont have to do any math at all to get an intuitive grasp of the number. With the super high numbers, it is easy to get the number of 0s wrong.

See: https://en.wikipedia.org/wiki/Film_speed#DIN.

Ironically, though the ISO system is used in theory, everyone but everyone only gives the ASA component! ISO combined ASA and DIN, as stated above (e.g. 100/21; 200/24). I don't know why manufacturers don't just say what they mean and call it ASA.

curiosifly: just interested in knowing that, between the Panasonic FZ1000, Nikon DL 25-500 and this sony rx10 iii, which one would everyone choose and why? I guess it will depends a lot on whether one shoots mainly still or video?

Rubbish. Not everyone shoots action all the time and those who do use something else anyway. I haven't checked the specs but I'd expect a decent weight difference. One of the big advantages of an "all-in-one" is to shed weight. This isn't necessarily a market for "big boys".

Or a G3X with clip-on viewfinder...

Peiasdf: At what zoom range would atmospheric haze/distortion begin to affect IQ assuming very clear day with unlimited visibility.

The longest lens I have is a 350mm eqv. on m4/3 but from DPReview's shootout of superzooms, it seems superzooms at full zoom all have bad distortion.

It's not the focal length, it's the distance. It's just that a longer lens magnifies the effect of atmospheric haze more. However, atmospheric haze is irrelevant if you aren't shooting at great distance.

Weather conditions hugely affect this haze. Shooting a lion in Africa in the middle of the day, you'll have that sort of distortion quite easily, even with your 350mm lens (if the lion is some distance away, not right next to you!). Shooting a bird in a forest with a 800 mm lens, you won't have that trouble at all.

FastGlassLover: Speed and reliability are not what landscape photgraphers yearn for, they will continue enjoying the D810/D750. Anyone who mistakes a camera's, such as the D5, lack in DR as a weakness is either naive, not a professional sports/journalistic photographer, or just a plain tech dork

I don't want a D5 personally, but to it is still an extremely capable machine.

I'm pretty sure landscape photographers want reliability! Luckily, very few recent cameras don't have that.

I haven't heard about it. How does that help us 4S users?

The headline certainly grabbed my attention and the comments below, as always, are a mixture of amusing and annoying. I'm wondering, who knows more about what they're purposefully designing, Nikon or dpreview staff/readers?

The whole dynamic range issue has gone haywire since all larger-framed cameras started to produce enough dynamic range for most people in most situations, so measurement got changed here by moving to subjectively examining shadow recovery (how much noise is too much? = subjective), while highlight range and quality of recovery is no longer reported on.

What really matters is how this camera shapes up against its only true competition, the Canon D1X2. Interestingly, Canon seem to have moved their sensor design in the opposite direction. I bet, however, that both will be ballistically capable where it matters!

In reply to:

vFunct: This should be obvious. When I first saw the ISO range, I knew it wasn't going to be ISO invariant.

You're not going to get ISO invariance with a sensor that can do 3.2 million ISO. The sensor's electron well depth has to be larger than the base ISO range for ISO invariance. The well in a modern camera only has about 100,000 electron capacity. And you have to have a perfect readout to even get that range.

Absolutely!

I was so annoyed with iOS7 I chose to move to iOS8. It actually brought a useful feature (I can text from my computer) but made the phone noticeably slower again. No amount of playing with settings or "Googling" could fix that. I also find I now have insufficient RAM often, unheard of with iOS5.

If you say you have "no issues" using the current OS, you don't do much with your phone or never had it's native OS.

I went from iOS5 to iOS7 and immediately many, many things I did required two taps where one worked before. Plain irritating and very much like using Android - a giant step back. It also started automatically downloading "updates" and jamming both my storage and my internet (these are very, very big downloads which take hours, they're not remotely trivial and I absolutely did not ask for them). I have found a way to stop that but it has cost much time and a little money. Then I had to go through the menus, turning off all sorts of things which slowed the phone or used up lots of battery power, which never happened on iOS5. Plus it was a little slower. That's all ignoring the child-like, "flatter" graphics which replaced the mature graphics it had before.

Cont'd...
