On article Samsung unveils 256GB EVO Plus microSD card (88 comments in total)
In reply to:

kayaro: That's great to have 55,200 photos stored but if the card go wrong than you will LOSE 55,200 photos at ONE GO. Oh, is the 10 years warranty include recover all the photos?

I think it is partly a demonstration, but as a MicroSD card, it is also intended for small cameras. Whether you're recording at HD or 4K, the extra unattended recording time will be welcome. There are few choices for high-capacity storage media that fit in a helmet cam.

A lot of people are recording routinely now at 4K as archival source.

There was more than one question.

The card will be useful for GoPro and other remote and video applications. It's fast enough to let you record at highest quality (as far as I can tell), and it has enough storage for a long run. That will be a boon for a lot of sports and extreme applications.

bgbs: I'm glad to know my ancient D700 does just as good as the latest cameras. I have no reason to upgrade after looking at D500 and D5 images.

I liked the D3, but I liked the D3s and D4 better. The D4 has great DR at base ISO, unlike the D3/s, and produces smooth shadows.

Caerolle: Wow, more nicely-composed images!

These are good days at DPR. The old dreary sample galleries have given way to an editorial staff that looks like they enjoy taking pictures.

The D700 cannot do anything above ISO 6400 to save its life. That sensor had so much blooming and pattern noise, that Nikon traded my D3 for a D3s at no charge. These new sensors are miles ahead of the D700. They do a good ISO 25600, good enough for publication. Then they keep going. The D700 produces pure junk under those conditions!

CopCarSS: Will "Life" be available to view online? It would be interesting to see the short made with this interesting camera and technology.

I'd love to find /any/ samples from this camera that can be viewed at more than 300y pixels. The embedded Vimeo player doesn't allow full-screen viewing in any of the samples. And even there, the actual samples from the camera, only a few seconds worth, are very hard to make out.

Are there other samples out there I'm missing? You would think they'd want these teaser videos viewable at 1080 as soon as possible.

It's a great idea. The convenience in compositing alone is worth the price of admission. But I'm puzzled as to why they wouldn't have HD samples up in time for NAB.

On article Hands on with the Hasselblad H6D 50c/100c (268 comments in total)
In reply to:

Alphoid: This is a serious question: Could someone explain a specific application which is better served by the Hasselblad 50c than by a Sony A7RII? By that, I mean technically and concretely describe a setting where a photo taken by the Hasselblad would be superior to one taken by the A7RII, and why?

I can (kind of) see the merit of 100MP for specialized applications, but the 50c just confuses me. I'm genuinely trying to figure out if this is a serious product, or if it's designed for the same market which would buy a Stellar/Lunar/etc., but a little less obvious.

@Alphoid, you're being unnecessarily skeptical about the benefits of sensor size and mid-tone gradation. These are real benefits. Fashion and product shooters will eat these up.

The 50MP sensor is the same as in the Pentax 645Z, or perhaps an update on it. It's not that expensive, since it is used in a $7500 body.

In reply to:

brycesteiner: Is there RAW samples for this camera to download? I would like to see how it holds up to pushing it 5 or 6 stops to see how it compares to the Nikon 5D. It looks interesting since MF is supposed to have much better DR.

DPReview - if you don't have it already, could you add the H6D to the RAW DR Exposure Latitude page?

The Hassy uses a Sony Exmor sensor, and we expect to see over 14 stops of DR with it.

The D5 is a different animal altogether, optimized for fast shooting and good quality at high gain settings. The Hassy isn't fast - it has to read out a large data stream, and do a black frame subtraction on every frame.

Then there is this, which appears to be exactly the same thing, for $112, also at Amazon:

This is similar to technologies being used in X-ray crystallography, in which a CMOS sensor is placed in front of a powerful X-ray beam after it passes through a crystal made of macro-proteins. The resulting dispersion when recorded yields enough data, together with the benefits of symmetry, to create a complete 3D model of the protein. [Watson and Crick and Ros Franklin were early practitioners.]

There are no optics for this application. The sensor is paired with a diffraction grating, and the point-spread function (PSF) is computed just as it is with the sensor described here.

It isn't quite breakthrough (and they are using an off-the-shelf sensor here), but it is an interesting incremental advance on existing ideas.

In reply to:

Kamox: Give me a 4 MP phone camera with really good dynamic range and high iso capabilities, instead.
The photos will be posted on FB or Instagram at 1024x768 anyway...
BTW, if a full frame sensor had this pixel density, it would create a 864 MP image.
With zero dynamic range, full of noise and a 18-core Xeon needed to process it, of course ;)

That's a lot of hyperbole to unpack. The advantages to more pixels is well proven. And those advantages can be realized even at web size.

This might be close to the limit for Bayer sensors. Then we'll look to Fossum's JOT sensor, wherein each pixel captures at most a single photon.

Well, if this means they "get it right" on the initial release, then we're good.

Luke Kaven: Turns out the NX-1 was a very good preview of technology coming down the road. Sony now has several features introduced with the NX-1.

- copper process for reduced heat and power
- full pixel readout for oversampled 4K
- continuous live view in action shooting
- PDAF everywhere with smart tracking

But I'm betting that Sony did one better on the sensor. I'm very keen to see this one in action.

Where does Sony say that this is BSI? I wasn't able to find anything.

If they're like Samsung, they gone to a 65nm process, which lets them pack loads of functions into the same space.

Joel Benford: It seems expensive for 2016. It could have IBIS at that price and not seem cheap.

I wonder if there will be an A6100/A6200/both at a lower price?

There is an enormous amount of computational horsepower and other updated technology in this camera. This is a new sensor with copper process, new CPU, DSP, finder LCD. It really is loaded. I actually think that they aren't making a huge profit on this to start, and might even be operating at a slight loss on each unit. [They sell their game systems at a per-unit loss in the first production run.]
