JacquesBalthazar: Let’s be explicit here: what we are looking at is 100% digital.

One is a set of files of digital captures produced through a scanner, the other is a set of files produced by a digital camera.

The first category is produced by capturing via a CCD pre-existing images of a scene as materialised on chemically treated pieces of emulsion, the second is produced by directly capturing actual live scenes via a CMOS. Then both sets are electronically edited, resampled and downsized to fit the destructive DPR publication requirements.

If the analogue chain advantages (tones, dynamic range, grain structure, etc) exist, they will have been dramatically compromised via their digitisation process.

Finally, there are so many effective film simulations available now in the digital processing chain, that you can mimic analogue quite easily for all practical purposes.

Sticking to an end-to-end analogue chain is the only way to witness its unique qualities (via a print or a slide projection).

Let’s be explicit here: what we are looking at is 100% from a human eye retina.

giorgionerd: I don't know what should I base my judgement on. Couldn't they simply shoot the same pictures and put them online side by side, with high quality files?

What I'm seeing here is random pictures of a distressed model. There's no possible comparison, because the files are low res, because the model wasn't paid enough and showed all her disgust, and because for a comparison you need to have the same pictures shoot in the same condition.

That’s not disgust. Just that normal fashion model face, told to look arrogant.

User3366538285: I am taking a step back to admire the evolution of Chinese upcoming domination of technology (and world economy). From the world of the 80s, when the only Chinese I had met where a government-sponsored couple with ill-fitting clothes in my MBA class....to now with this sleek marketing announcement of yet one more hi-tech marvel. Hmmmm... I should start Chinese.

Reminds me of ≤1990 when the world was in awe of Japan world domination.

If you look closely into key indicators of Chinese economy you'll see they are in deep trouble. E.g., a large part of their buildings are built for speculation and w/o habitants. And companies have tremendous debt. Already now Chinese growth rate is down below 7%, just twice of developed countries like USA or Germany (3%). That's not enough anymore to catch up with the West.

falconeyes: I don’t want to leave another negative comment ... but I don’t get the 1000x magnification. Even a full frame 4k pixel is 9micron, anything beyond 20x (below 450 nm) becomes a blurry mess due to the finite length of visible light waves.

Maybe it is 1000x as ratio between the focal length of the two lenses of a microscope. But when photographed, it isn’t 1000x anymore. This shouldn’t be confused with macro magnification rates. I’d say macro magnification is pretty moderate here, more like 5:1.

I guessed so. But this implies he left the eyepiece in. It is more normal though to replace the eyepiece by the camera adapter. Anyway, a 180 micron FoV makes little sense for claiming 4k quality, even webcam quality.

Its the Mavic Air.
DJI has already set up an URL rewriting rule for anything http://dji.com/mavic-air/*, obviously hiding a section of the website, already prepared for launch.

US could forbid Google to export Android into China, for “security concerns”. Would be a much cleaner move.

What about the primates called homo sapiens? If I understand correctly, images of said primates on Shutterstock must now all be fully unclothed!

Interesting, I looked it up. Seems Autel is Chinese with additional US and German development locations. Quantum Systems (https://www.quantum-systems.com from Munich) seems to have developed the collision avoidance with Intel and Autel Germany. At least, this is what I found from career pages and news articles.

Quantum has some cool wing-quadcopter which flies at 160 km/h and for 2 h :)

Much more exciting news!

Yes, and cheaper. But they don‘t stream.

ProfHankD: Er, this isn't selling for $100. There is a $99 fee to enter into a reservation agreement, which then has you go through making an actual order when the product is ready (in Summer): https://cdn.shopify.com/s/files/1/0301/6769/files/Reservation_Agreement.pdf?18234079904097439621

Thanks.
Plus they advertize their $99 as reduced from $199, as if it *were* an actual preorder (and they call it such too).
It pretty much sounds scam or fraud to me.

Esp. as they make it pretty clear in the fine print that reservation fees are *no* secured asset of the company, ie. allowed to disappear ...

This actually is an ICO of WENN, wenn.com . They licensed the right to use the name Kodak for riding the blockchain hype.

Why doesn‘t it have a price?
Hardware is almost the same as the Yi 360 VR, only stitched into a different (ie. simpler) format. Should have the same price announcement, ie. $399. The tiny back screen shouldn‘t add to the price, now that we are later in time.

On article DJI announces Osmo 2 Mobile smartphone camera gimbal (83 comments in total)
In reply to:

Roland Schulz: I wonder if this will work with in phone OIS system.
I had the OSMO mobile and it didn´t work with my iPhone X, always had jitter in the recordings! A well known problem if you do a google search.

@Terkwoiz,
to answer your first question: the Sony has a single gyro sensor unit (one input).

I have no definite answers to your other questions. As I understand it personally (and my tests with Osmo and iPhone X seem to confirm this), the lens within the iPhone simply isn‘t hold tight enough to withstand shocks when carelessly walking. OIS on seems to help, maybe because then the magnets are driven stronger.

No, it doesn‘t defeat the purpose of a gimbal. It is no toy, it is a tool to capture cinematic footage. The average consumer won‘t use a gimbal. Careless walking defeats the purpose of a gimbal, not the other way round. I tried it and when in ninja walk, the Osmo/iPhoneX footage not only is jittery free, it is butterly smooth, without those ugly up and down jumps. Almost looks like from a dolly slider, cool :)

falconeyes: For whoever believes we don‘t have inflation ...
Nikon announced the predecessor in May 2010 for exactly $6,999.95 or 56%.
And it isn‘t even more lightweight ...

It actually *IS* inflation.
But because of the increasing spread between poor and rich, the explosion of passive income sources, the inflated money is spread among the richer and seen as price inflation of goods the poor cannot afford. Unfortunately, it isn't measured by nominal inflation and fiat currencies do actually erode.

That OIS can‘t be turned off is in conflict with
https://developer.apple.com/documentation/avfoundation/avcaptureconnection/1620484-preferredvideostabilizationmode

Some Apple devices can apply BOTH cinematic (digital) AND optical stabilization even in video (e.g., the 6+ can‘t). There is a lot of confusion about the topic out there.

I didn‘t claim you said Sony and this case are similiar. But you claimed they are analog (i.e. some insight learned in one case can be translated over). And I explained why they aren‘t even analog.

The Sony case is one input device (motion sensor) controlling two dependent output devices (IS motors). The Osmo case is two independent input devices controlling two independent output devices. Its not even mathematically related.

In reply to:

Michael Long: Like the idea (and the price), but would like to see image samples. (Can't find anything on the site.) The editing environment also seems somewhat limiting compared to the "go here" and "follow" / tracking modes available in the Rylo.

I assume that there is little difference to the Insta360 ONE when it comes to software. AFAIK, the Insta360 software offers at least as many options as Rylo and actually pioneered „go here“ and „follow“. Moreover Insta offers desktop software, not just mobile apps.

DxO Labs may have outsourced lens and sensor profiling to DxO Mark now.
But both companies‘ job offerings have too much overlap for this to be plausible. Must be a pure book keeping thing.
