On article Galaxy Note 8 to feature 3x zoom dual-camera (25 comments in total)
In reply to:

Ebrahim Saadawi: 3D Depth feature that to blur backgrounds: I have always wondered why aren't companies doing this? It's incredibly easy in hardware to scan subjects distance in a scene, and then compile a software code that blurs the background gradually from the farthest subjects to the nearest. (It's not light field, we can't change focus after taking a photo here)

Wouldn't this create 100% authetic shallow DOF? Controlablle too, in amount (1.0? 1.2? 1.8? 2.8), in look (harsh? Creamy?) In charachter (swirly?! Oval bokeh?)

You can make your 28mm and 50mm lenses on your phone any lens you want in terms of look!

-The critisizm for current iphone/android blurring is that they simply detect the subject you want to focus on using luma/chroma contrast which results in edge errors (many) AND most of all that the drop in DOF happens aprubtly around the subject with no natural roll-off. This solves both.

To acheve that It would probably require a very fast and very accurate focusing system and that on every pixel level ! so you can have an accurate distance information for whole image. Not impossible but very unlikely in near future

On article The Sony a9 is a 24MP sports-shooting powerhouse (1908 comments in total)

"Exmor RS™ CMOS sensor – the world’s first of its kind – which enables data speed processing at up to 20x faster than previous Sony full-frame mirrorless cameras"

So it means that there will be practically no Rolling shutter effect?!

ADiStefano: Interesting read alongside this:

http://www.eoshd.com/2017/01/opinion-dxomarks-camera-scoring-makes-zero-sense/

Dxo overall ratings are as subjectives as Dpreview's ones, what counts in their test are their charts, so forget firstes ones.

BlueBomberTurbo: Now if Canon would only give in and use Sony sensors in their DSLRs, too...

photenth "First of all most canon users don't care" so Canon users just don't care about better IQ while all others do ?

WesPerry: This thing looks like a cheap children's toy compared to the PhaseOne XF. I'm sure performance will be comparable.
Also, even though I'm a Sony fanboy, it's a little sad to see that Sony is supplying all the medium format sensors. Is there no one capable of competing with them??

Marcio all you said shows me right, I mean I wasn't saying MF IQ was a crap, not at all, I just saying that it would be much better if their sensors were developped at the same speed that thoses on more compact cameras, I dont think that with todays technologie you have to compromise so much high ISO quality to have a good base IQ. The poor performance of MF in that area shows the oldness of that tech, a good tech responding to needs of pro but still an old tech.

marcio_napoli That's why they are stopping use them ?

Yep, that is also the raison why past generation MF sensors were so outdated, nobody developped them and then came Sony and put it's profitable small sensor tech into MF, without growing smaller sensor market the MF would still have kodak 2000-ish sensors.

ARTASHES: This is actually an APS-C DSLR with f4.5-6.7 17-400 OIS lenses.

I was talking about low light performance, 1" type sensor being 1 and hald step worse than APS-C, I just put down max aprteure by an a half and step.

No need to hope, it's about 2 steps better than 1/1.7.

APS-C sensor sized camera if you prefer, but theorically and technically I think that it's faisable but it's an other story. I just did the equivlance.

Curious to know how fast it drops to f4 in zoom range

Sony jpeg engine can be pretty bad et mid ISOs, even on Sony's last FF cameras, some pics looks like crap, especially in shandows.

phazelag: I wonder where all the arm chair lens engineers who have repeatedly told us what cannot be done will hide now?

The question is how soon the lenses will go down to f4 in zoom range.

Compared to D7200 luminance noise on Sony looks kind of washed out which gives impression of less noise in monotone areas but in fact it looks like if there was some NR

Photato: Larger pixels than Note4, 5 and S6, good.
But too bad they went back to that pesky 4:3 aspect ratio.
They keep moving things around so we never get the perfect specs.
For me is 8MP and 3:2 AR.
Sticking to my beloved Note 4.

Larger pixels (especillay when the difference is so marginall) mean nothing. It's all about marketing, just like HTC ultrapixels. Only sensor size will change the IQ.

A question please : how much more time it takes to capture in "Pixel Shift" mode a photo that would take 1/100s in normal mode ? 1/25 ? or there is some addtional interval time ?
