Personally, I respect (some) people and (some of their) rules rather than places or "memories". And I don't go to places, where I feel uncomfortable. I see no point in visiting Auschwitz. I believe people that decided to go there may take any pictures the want, unless they don't make any measurable damage. Staying on a rail harms nobody. All this stuff is a matter of taste. (Asking for "respect" is also OK. Just don't insist too much or at least don't harm anyone while insisting, please.)

redhed17: Do all tech company/organisations purposefully go out with the intent to confuse! HD TV formats, the many SD card sub divisions etc. Talking of formats after the one that is not even on the market yet!

I had to buy a replacement power supply for my laptop a few months ago, good luck to anyone trying to find out which power connection is on the laptop so you know which to buy. I ended up buying a universal supply that came with 9 different connections.

Does the confusion help sales! It must do, because they all seem to do it. :-/

That's a side effect of diversity in the free world. In North Korea, things are much more standard and simple, I guess.

Artem Sarafanov: What's point of a multi-camera/sensor design, when Google showed what 1 sensor can produce! We only need an optical zoom to be properly implemented. Folded optics may solve the issue by employing only 2 sensors. Imagine a folded camera desing with only 1 entering pupil at the back of the phone. The mirror behind the pupil flips from the left to the right. When the mirror is 'left-oriented', the light goes left to reach the left sensor. The optics the light passes when going this way creates image circle eqv. to, say, 20-40 mm focal length (i.e. it is only a 2x zoom). When the mirror flips to the right, light from the entering pupil goes to the 'right' sensor. There, we can have, say, 40-80 mm eqv. image. As a result, the phone has only 2 sensors and 1 entering pupil thus avoiding any paralax when switching between the sensors. Add to this Google's magic processing, and the job is done.

@Marcelobtp Depends on what you call "knowledge". The algorithms implemented in by Google in Pixel phones have recently been explained in detail by DPR. Yeh, I know nothing. It is simply a magic.

@Yandrosxx If using mirror is impossible and a kind of flipping/shifting prism is also not an option, then at least it is possible to make a phone with 2 separate folded zooms (and still 2 sensors in total). Like I said, one for e.g. 20-40 mm, another one for like 40-80 mm. 2 folded 2x zooms, I guess, are not hard/expensive to implement. And they can be rather bright and of good optical quality (unlike 4x or 5x zooms).

@sportyaccordy My comment is about using 2 sensors + zoom vs Many sensors + fixed lenses. Using multiple exposures is about how to deal with small sensor size. I don't think the new collaboration is going to bring larger sensors to phones.

FF is good enough.

ShaiKhulud: Really happy for Tamron. 28-75mm F2.8 Di III RXD is a fantastic lens for the money.

Overall, great choices. Sad that Pixel 3 is unavailable in Russia though.

You can buy it from iCult web store.

noisephotographer: Is Night Sight + raw possible?

At least they could add stacked raw without the AI colour magic applied.

noisephotographer: Is Night Sight + raw possible?

I hope they will be able to add NS raw later. But the fact they did not do that from the beginnig may indicate that there are too much data to stack properly in the NS mode. Otherwise, the NS is fantastically good. The absence of raw is a sad caveat.

Sorry, my fault. Exposure compensation is available in NS.

No RAW, no exposure compensation in the NS mode on my Pixel 3.

Now, when Android-based cameras exist (e.g. bulky and odd Zeiss ZX1), we will probably see these brilliant technologies in a "real" camera pretty soon. Maybe through a collaboration with Google and using a sensor smaller than FF. Sony's tech-based stacked APS-C sensor with fast readout and moderate MP count should be just ok.

rbach44: This might be the weirdest camera announcement in some time.

Why would Leica collaborate with a brand that has almost no reputation except for making very bad copies of Leicas back in the day?

What camera comes kitted with a 35mm f1.0?

What camera proudly boasts "DESIGNED IN KRAGSNOGORSK" on its top plate?

Still not as sad as the Hasselblad Lunars, however...

Krasnogorsk means "Red Mountain Town/City". It is located not far from Moscow, the capital of Russia.

I couldn't find a word about the write/read speeds. Is this thing a giant slow microSD card?

Oleg Ivanovskiy: Here in Russia we despise such characters. What he is doing is just monetising all this crap and grim life for grants, he's just using it to build himself a name abroad, Instagram and all that biz. He's just a smarta**, walking on others shoulders. He doesn't care much since he got enough to get out, he's just giving what is trendy. Well, he did work in orphanage, although we don't know anything about it beside stealing shirts from orphans. And some images look like a staging - like this soldier, for example. What is he doing with his AK in the mist?

@dr.noise Yes, I did speak for myself, describing the composition of the society, as I see it. When opposing "brainwashed haters" to "open-minded people", I certainly hope/belive I belong to the second group. Regardless of the degree to which my brain is washed or my mind isvopen, I am at least not a hater. I don't hate or despise anyone and that is why my question "who are we"? Yes, I was hinting that I do not belong to those "we", even though I am Russian and leave in Russia.

@buratino I don't know much about RT except they have huge budgets, while the media product the produce is closer to trolling than to anything else. It is really hard to defend hardly defendable and promote almost non-promotable... I don't know how this compares to BBC. I guess BBC is in a better situation, because they do not need to call apples oranges.

@dr.noise I am a scientist, oceanographer. And when I speak, I speak for myself (and certainly not on behalf of "us", the great people of Russia).

@miric As in any country, people are different in Russia. There are a lot of brainwashed haters, but there are open-minded people as well. The latter are minority though.
