Well, maybe not this, but if Samsung made a native grip for Note/Galaxy S with the ergonomics of an NX500 with a tripod mount and a functional hot shoe, then I could be tempted. Or if Sony did the same for their ZX line inspired by an A6500...

blackcoffee17: Why is that telephoto cameras on phones are always such a bad quality compared to the wide angle camera? Is it so much harder to make a 40-50mm focal length lens in such a small size? I thought it would be easier to design than a sharp wide angle lens.

Good explanation. Thanks, noise!

The numbers from noisephotographer may well indicate that the tele and wide lenses are not just similar, but *identical*, that only the sensor and pixel size is smaller for tele. This might make it easier to combine pixels from the two, but otherwise makes the tele lenses rather limited in usefulness.

Tommi K1: Nokia ain't doing anything, HMD global is...

Nokia is a networking company, that sold it mobile division to Microsoft, and licensed is brand for mobile phones.

Nokia is still a own company....

There's a reason HMD is across the street of Nokia headquarters in Espoo. Much of their staff is from Nokia's old mobile division, so one may argue they are more Nokia than Nokia these days.

Kristof77: Come to think of it, if Panasonic made a Lumix mirrorless camera that could be used as a phone, I would probably ditch my mobile for good:)

The Red Hydrogen phone has an optional camera module with replaceable mount (Canon, Nikon, Fuji etc)...

tinternaut: Well paint me surprised. Google seem to have pulled out of making their own tablets, and it looks like the future of none iPad/Windows tablet is going to be Chrome OS with tablety skin and Android app compatibility. I think that’s the right way to go, but it’s a long way off (the Asus Chromebook tab demonstrates why). This new Samsung looks nice.

Who buys Android tablets these days? So many of them seem to come with a version of the OS that’s two or three generations old. Meanwhile, entry to the Apple ecosystem, via the entey level iPad isn’t all that expensive. I’m still using my old iPad Air 2, and a Fire HD 10, for the commute, that I picked up on this year’s Prime Day sale (a lot of tablet for the money, but not so good for the photographer).

DeX looks so close to Chrome OS for tablet that Samsung are halfway there already.

Do you have the Asus Chromebook Tab? I do, and I suspect most of the negative reviews are from Chromebook users missing a keyboard. Coming from Android, it's a nice and clean (no bloatware) experience, especially if you spend much of your time in a web browser.

PapiSnarf: The only thing that Sony needs to work on its a redesign of it a phone. Huuuuggeeee Bezels in 2018 is no longer acceptable.

Their image processing wouldn't matter much if they offered DNG/RAW, like this sensor has native support for (in two resolutions, even). Not holding my breath for that, though...

Oleg Ivanovskiy: I do not get it. Why make 48 Mp sensor with this strange Bayer filter. Its effective resolution is just 12 Mp, other is just interpolation, you cannot switch filter colors. They give us this funny picture with Princess cruiser, that's a simulation, not a real world comparison. Why not make 12 Mp sensor with 4x bigger pixels and normal Bayer from the beginning? Is it too simple for Sony?
My only guess: that's to fool people who do not know a thing about colour filters. 48 Mp in my phone, wow.

Actually, the color resolution is better than 12MP Bayer, since you can still divide the sensor in blocks of 2x2 pixels where every block has 2 green, 1 red and 1 blue independent sensor elements.

In reply to:

photoaddict: Are they going to create just a 12MP output from a 48MP sensor?

A 48MP sensor with a regular Bayer filter downsampled to 12MP would be much closer to Foveon in terms of output than this one which remains a Bayer even at half resolution. Interesting concept, though, and backwards compatible with existing RAW converters...

On article Samsung Galaxy S9 Plus Review (220 comments in total)
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? (1071 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.

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...

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 (425 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.

Link | Posted on Apr 27, 2018 at 21:08 UTC

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.
