On article Photokina 2016: Hands-on with Hasselblad X1D (137 comments in total)
In reply to:

Wild Light: Hasselblad would certainly win the beauty contest. But it just seems the Fuji is better developed, better priced, has better lenses and IMO, some better features. If it weren't for the fact Fuji was about to release their own system, they would most likely be making lenses for this Blad. The Blad lenses are slower, and the systems leaf shutters mean their lenses will remain slower. I prefer the way the Hasselblad looks, but the Fuji is the camera I will buy.

It is "slower" in the sense that it limits the size of the optical path to only as big as the leaf shutter will allow. But you don't need f/1.4 or even f/2 on a MF camera. An f/2.8 lens is sufficient on the fast end.

You're right about the advantages for fast sync speed. If you have fine control over the strobe timing, you can sync at 1/1000th sec.

Luke Kaven: There is a big difference between increasing dynamic range by increasing the headroom versus lowering the noise floor. One increases DR at the top, the other at the bottom. For cinema cameras advertising 16 stops, the added stops are at the top in the form of overexposure protection. In cinema, you don't want to blow out the sky. But this is not the same as lowering the noise floor, which is where Sony sensors have made the most progress.

AshMills: You didn't understand anything I said. These are two very different ways of solving the problem with very different implications. [Before you pretend to be embarrassed for someone else, you should double-check that you understood them.]

Luke Kaven: What a remarkable self-promotion for a photographer whose work seems only average at best. I'm not sure why it ended up here.

If one cares, my site will be back in a couple of weeks. I think you have a different aesthetic sensibility, and some of it is quite nice. I don't think you understood me, but that's ok. I don't feel I need to be embarrassed about my own work, or disqualified from critiquing a feature on DPR. I understood the artists I worked with well.

I didn't think of it that way. He seems like a nice guy. I don't have any reason to think he makes a lot of money. I think he's on a personal journey, living on his own means mostly. And that's cool. I just didn't think the images were enough to hold up as an example.

I just didn't think they were special enough to merit front-page coverage. As the next commenter down says "video footage was more interesting than the photos". I did not see elements of good composition or a good street style. Liked the video though.

Do feel free. My site is going back up in a week, but there is a flickr profile in the meantime.

happypoppeye: Some interesting pictures but any one of them could have been taken from a helicopter which makes a lot of the statements invalid.

Yeah! They could have been taken by anybody in an anti-gravity suit.

These look like linear captures, even with the listed "minor adjustments". These look like fine renderings for further processing at 16 bits. But it looks like the standard tone curve is not in these profiles yet.

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 (267 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.
