On article OPPO to announce 10x lossless smartphone zoom camera (165 comments in total)
In reply to:

BorisK1: The zoom looks similar to the folded light path optics used in "tough" compacts - which aren't exactly known for their stellar IQ. A dedicated WA lens is a nice touch though.

Not stellar compared to other small-sensor compacts. Not talking DSLRs here.

HowaboutRAW: From the illustration, it looks like the lens will be slow, like most internal zooming tough cameras.

@ Revenant:
Thanks, that makes sense! In that case, it could be a very nice combination of a fast wide-angle fixed-FL lens, and a slow zoom.

David610: Lossless smartphone ... I'll be able to sell it in three years time for what I paid for it? Deal!

Maybe it's "lossless" in the sense that you can't lose it. Even if you try. Even if you lock it up. It slithers through shadows, following you around on thin spidery legs, snapping and growling at any other phones you try to touch.

Lasssst phone you'll ever own.

Hmm, wait. Now that I think about it, I don't know why I assumed that the second lens is a zoom. It's positioned the same way they place a zoom lens in tough cams, but the pic only shows five elements, which seems like too few for a modern zoom lens.
If both lenses are FFL, and they use fancy interpolation to "zoom", it's not nearly as exciting as I first thought.

> That's not what the illustration seems to say,
The illustration shows two separate sensors. The one on the right is on its side, behind a zoom lens.
The one on the left is mounted flat with the bottom of the phone, behind a FFL lens. The lens is "exploded" to show individual elements, but in reality, it's shallow enough to fit into the phone.
I was talking about the FFL lens on the left. That one is likely F:1.5. That's what the other phones if this manufacturer have.

It's a two-camera system. The WA camera is fixed focal length, providing reasonable low light performance.

Colin Stuart: $1.1k for a 1/2.3-inch sensor??? what a scam.

The waterproof models have a 1/5.8″ sensor.

nickolas84: This should work with about the same amount of light as an M43 camera.
Now Google has already done that. 15 exposures on the new Pixel is about APSC size territory to be exact!
But if this really is 10 times more light on top of the existing technologies ...then Oh boy!

@Max Iso: You might want to check out www.light.co - they already offer some of the things on your list, it's just a matter of a phone manufacturer picking up their tech. Looks like Nokia is their first big contract.

Don't know how much market demand there is for a phone with an articulating screen though.

It's likely 10 times more than a "typical" phone, not a "flagship" phone. If "typical" means 1/3.6" (12.0 mm ^ 2), ten times that is very close to 1" (116 mm ^ 2), or about half the area a 4/3 sensor (225 mm ^ 2).

Which is still awesome for a phone, especially if it can use the extra resolution for a 4x zoom.

On article The 10 most inspiring drone images of 2018 (213 comments in total)
In reply to:

John M Roberts: Seems to be more of a show for creativity in the post processing part that happen to be from drone takes. Some of the explanations are too vague to get much from it all. In the last one of fall colors, did the photographer place the subject in the actual scene or did it mean the person was added in a composite? The circle of boats? Interesting pattern but what was done to the actual shot to make the complete circles for I don't see any way of the boats entering or exiting. Like I said, more showing the art and skill of processing than drone images. I would have preferred seeing a bit less fabricated scenes for nature certainly can provide plenty on its own to be viewed especially with how easy and popular image gathering is now.

The description says that it was a straight line of boats, photoshopped into a circle.

HenryEckstein: Maybe I am just old and jaded or so used to ultra high end gear that the Red Hydrogen phone to me is just a MEH! phone.

THIS IS A REAL SMART PHONE:

2) 120 Hz refresh rate

3) AMD Ryzen-2 Combined CPU/GPU 3.7 GHz 8 cores 16 threads

4) 256 Gigabytes of SYSTEM APPLICATION RAM

5) 4 terabytes of onboard SSD Flash Hard Drive (Removeable)

6) Thin-Film multi-3D-Stacked Lithium Ion Battery 25,000 Mah
24 hours solid video playback runtime and 14 days standby

7) IP-69 FULL multiday Water and Dustp-roof Mil-Spec rating on all-Titanium case
and Solid Sapphire Crystal Screen face with extra G-shock and Multi-Axis
Vibration resistance.

You think this is a phone?

Looks very much like Olympus Air A01 circa 2015.

On article Nikon Coolpix P1000 Review (658 comments in total)
In reply to:

(unknown member): The review stresses that the slow maximum lens speed causes diffraction when the actual aperture is huge given the focal length of the lens whatever the f number says.
I always thought diffraction was the result of a large proportion of the light travelling over the the aperture blade edges in relation to the light travelling through the orifice.
I am extremely interested in the mechanism how the f number or even worst the equivalent f number causes diffraction in what is a massive 67.4 mm aperture.

No big mystery there. If you take a picture of a point, like a star, diffraction smudges it into a disk instead of a point. An airy disk is what they call the smallest possible size of that disk you could get, using a theoretical lens, perfectly focused.

The 539mm focal length and 67mm aperture, mean airy disk diameter of 10.7microns (0.0107mm):

If the sensor is 6mm wide, it's 1/560 of the frame width, or 1/420 of height.

Old Cameras: Still can’t get over the stupid faux advance lever, or in this case “thumb rest”. You’d really have to look hard to realize this is a digital camera since it’s trying so hard to masquerade as a film camera.
The app connectivity is a step forward in functionality but otherwise form follows style and it’s just ridiculous.

Hate the modern look. No black blanket, no shelf for the phosphorus, no rubber bulb for the shutter release.

Ergo607: If Ricoh (or Olympus for that matter) would release a rugged 1" sensor and a 28 or 35mm prime they would have my money already...

There's the SeaLife DC2000 - 1" sensor, 31mm equivalent, f/1.8.
Supposedly, you can buy it without the housing as a "spare part" on the manufacturers site.

kobakokh: with this specs price will be under 1000 USD, maybe... Because of Nikon D610 is way way way better camera and cost 1000... Here is just sensor and lens, nothing others...

It's zeiss. The lens alone will be over $1000. And a full frame sensor won't be much less. The body is extra. But they'll throw in a free USB cable.

In reply to:

jackfrost15: A little more reach and I would have surrendered my LX100 for this one. Even 90mm would have done it. But a thousand bucks for marginal changes is just too much.

The increase in resolution gives just about the reach you ask for: 75×(√(17÷13))=85.76

sh10453: Almost 1 kg for the 50mm???
Doesn't that go against the whole purpose of the mirrorless system, which is the light weight?
But I guess the L lenses couldn't be made lighter.
I have the 50mm f/1.2 L FD, and it's quite heavy compared to other 50mm non-L lenses.

@ManfredGrebler BorisK1: "The Nikon DSLR 1,2/50 AIS (same period than the Leica lens) has only 380 gr"
Right you are, I missed that one!
