In reply to:

I have a dream: "Dual-aperture gives the wide-angle sensor more light in dim conditions"
I really don't understand that.
Why does the dual aperture f1.5 / f2.4 give more light than a single aperture f1.5 ?
More light is given by the wide aperture, not by the fact there are 2 apertures.

Sorry, English is not my mother language, I hope what I wrote is understandable.

Judging from the RAW sample, they need the f/2.4 aperture because the lens is far less sharp at f/1.5 than the fixed f/1.7 lens of my Note 8.

On article Does sensor size still make a difference? (1058 comments in total)

As long as sensor size matters among phone cameras, I'd say yes. The best phone camera on the market today is the Huawei P20 Pro which also happens to be the one with the biggest sensor.

Everything else equal - size still matters.

Well, how much can you charge for smartphone accessories? ;-)

Not only is it married to two cameras on each side of the phone, it also allows display of commercial 3D movies.

To produce a 3D movie, you would likely need to buy or rent twice as many RED cameras as for a 2D movie, so it surely makes sense for RED to push 3D adoption everywhere...

In reply to:

photo_rb: Thanks, this is really great for me as I was just looking for a camera like this. I am a little disappointed to find there is really nothing available with a larger sensor like APS-C. I guess that is where you get a little more serious and go with an underwater case.

On article Why smartphone cameras are blowing our minds (449 comments in total)
In reply to:

MiraShootsNikon: The smartphone v. "real" camera trope is starting to feel much like the digital v. film trope. People like to fight, even though everywhere else the battle ended quietly, a while ago. Film is niche; "real" cameras are too, or will be shortly.

I think niches are fun, enriching places to be.

Nonetheless, I understand the substance of "adapt or die" barking, if not the abrasion and schadenfreude. ("Or die?" Sheesh. We're just talking about cameras.) But life *is* a series of meetings and partings; nothing lasts forever.

Personally, I will miss regarding photography as a direct expression of human craft. I suppose somebody will have had to train the AI choosing our exposures, our depths of field, our colors and tone; the AI culling our frames and laying out our presentations. So we'll thank Google researchers rather than each other. And I suppose we will still be pointing the camera ourselves--for a while yet.

Still, I will miss what it used to mean for someone to make a photo for me.

Well, give each smartphone a 360 degree camera and we won't even have to point ourselves...

But in all this talk about computational photography, it's refreshing to see the Huawei P20 Pro take the lead by primarily using a larger sensor.

Why no DNG/RAW shots? That's where the 40mp sensor appears to make sense and where you *could* see a difference with a much smaller sensor like in Pixel 2.

In reply to:

Gesture: Will there ever be another SIgma camera?

caterpillar, with a fast enough global shutter and modern processing power, it may be more logical to simply shake the sensor and capture all colors at the same position in rapid sequence.

Foveon cameras tend to have their own personality and being different from the major players is interesting in itself in these smartphone camera days.

Yes, he confirmed the development of a new camera in a presentation at CP+, but without any details, like if it's the next DP (fixed lens) or SD (interchangeable lens) series.

Sigma has been piling on new patents in the area lately, will be interesting to see if they make it into that camera or if it's for a future sensor generation.

gordonpritchard: Over engineered?
In a world where major movies may be filmed using iPhones, GoPros, and DSLRs would these Canon lenses really make an image quality difference when viewed on a TV screen - even a UHD TV?

28mm equivalent iPhone vs 37-3200mm (6400mm with extender) equivalent Canon zoom. Yeah, that's visible.

WesPerry: “...a maximum aperture off f/1.7 at its wide-angle setting, which lets in more light than any consumer-grade zoom lens on the market—even the high-end DSLR lenses.”
Umm...okay.

Well, it's a constant f/1.7 up to 340mm. The article may focus on the wrong point, but it's an impressive tool.

crop sensor with no e-mount option, unfortunately

No point in E mount when the sensor is slightly smaller than in a RX100.

sportyaccordy: Good for Samsung. I'm still waiting for someone to make a single FL multi module phone camera. There has been a lot of promise shown by separating out color and luminance channels

The Essential Phone does just that.

Really cool idea. The resulting DOF is so extreme that it almost comes across as computational in these portrait-mode times :-D

Tungsten Nordstein: What is the patent-able factor here?

@pannumon is correct, this isn't a general patent on fingerprint scanner on a camera - most phones would fall under that category after all.

cosinaphile: another wasted opportunity to use a 1 \1.7 or 2\ 3 sensor

why does sony ... the world leader in sensor technology ,... consistently fail at delivering a decent cameraphone ?

The lack of RAW support is particularly sad, preventing their own phones from delivering as good image quality as the very same sensor in a competitor's phone. Otherwise Sony phones are quite interesting, I'd buy one with RAW if only to get that dedicated two stage shutter button.

About 107mm, if you consider the G mount version.

Lordemed: The arrogance of Leica and other German manufacturers in overpricing their products amazes me. The more they charge, the more the 1% want to buy.

Sony's Mark XVII model scheme is starting to make Leica look affordable, though...
