On article Sigma releases X3F Raw conversion plugin for Photoshop (92 comments in total)

dr.noise: Why no support for older Sigmas like SD9-SD15?

I used Adobe DNG converter with (original) DP2 files, so believe most compacts are supported too.

Because Adobe support them natively?

snowsurferDS: The MFT version is 380€ in a local shop with a 3 year warranty....this just might be the alternative to the Oly 75 1.8 that I've been waiting for. Half price, more usable focal length for portraits and opens up a bit more....let's wait for the tests but I'll be watching this one.

Sigma's current mirrorless is sold in two sensor sizes (and prices) and their announcement of making APS-C lenses for L-mount makes more sense if they're not just intended for Leica cameras...

Even on a FF sensor, one may prefer to use a smaller lens sometimes and L-mount cameras auto-crop when an APS-C lens is mounted.

I look forward to this lens on an L-mount Sigma Foveon camera, but I suspect the 75mm/1.8 is a better lens on MFT if it's twice the price and designed by the same team ( https://www.dpreview.com/articles/6389121961/did-sigma-design-the-olympus-m-zuiko-75mm-f1-8 ).

jim seekers: So what is the best chipset, Qualcomm Snapdragon or Exynos.

Just one year earlier, Samsung's Exynos 8895 was slightly faster than Snapdragon 835 in Note 8, so I wouldn't jump to conclusions on a single generation.

3pgrey: 7nm is pretty amazing. Without phones I don't think we'd see this for decades to come

@SteinL what I'm saying is that they call an architecture "7nm" not because it *is* 7nm but because it delivers the same performance improvement over 14nm that one would expect by simply shrinking the 14nm chip to 7nm. It's marketing, not physics.

paulfulper: The time is ripe to use smartphone processors in a full size desktop . A new motherboard could take 4 snapgragon 855 combined and rival the AMD Ryzen 2 2700 in most applications including 4K gaming and video editing .
With very little heat and power draw.

Actually, when a mobile system goes to laptop size, they tend to switch to laptop processors instead. All the most powerful Chromebooks (which run Android apps through an Android subsystem) use Intel chips.

Yeah, but that's because it isn't, it's a bit like a BMW 330i which now has a 2.0 litre engine. "7nm" isn't a measurement, it's an equivalence these days.

DiffractionLtd: Sigma creeps toward OEM pricing.

Well, the 85mm Art has the highest DXOMark of any lens from any brand and this new 40mm has better MTF charts, so it may actually be a steal...

In reply to:

wootpile: Pricing looks very decent.... but I would rather have had a 40 2.0 which would have been soo much smaller, and easier to construct for sharp wide open. Even at current price and technological level, I doubt the 40 1.4 will have sharp corners until 2.0 annyway

According to Sigma's MTF graphs, the 40mm f/1.4 has similar corner performance at full frame as their dp2 Quattro has at 30mm and f2.8 on APS-C (45mm equivalent field of view). That lens is almost as sharp wide open as it ever gets (razor sharp, that is), so I expect the 40mm Art to be impressive even wide open.

EskeRahn: I like the idea of it NOT requiring software installed. (I had one that required that many years ago)

But where is the physical switch for write protection?!?!?

If you care enough about the security of the content to have it protected, you are quite likely to NOT want to risk having it infected or deleted when inserted in another machine...

It's Windows only, so not so sure about that no software thing. I'd buy one if the entire fingerprint reading+writing was self-contained in the USB stick and worked everywhere.

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.

On article Nokia allegedly working on 5-camera smartphone (143 comments in total)
In reply to:

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)...

In reply to:

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...
