princewolf: I can't buy one, so doesn't interest me. Waiting for Sony or Fuji to come up with that fixed-lens medium-format mirror-less for under 5000 bucks. Might be a long wait :)

The D810 and the A7R are comparable in price, within a small degree. The price difference between the Alpa bundle and a comparable Pentax system is enormous. One is left wondering what one is paying for. Is it brand mystique?

Meanwhile, there's the 645Z with the same sensor chip for $8500.

Cameron R Hood: So for the price of SIX Pentax 645Z's, you get an extra 10 megs, but the ISO tops out at 6400 (the Pentax, an astonishing iso 204,800)...they'll be selling tens of these...maybe...

It's the identical sensor. 50MP in both cameras. As for the ISOs above 1600: they're all digital scaling anyway. Expect that they will both perform as well. There's no analog front-end magic involved. The Sony sensor delivers digital right off the chip.

Worth remembering that this is a mere bundle consisting of off-the-shelf items -- IQ250 back, Alpa technical camera, Rodenstock lens...and a clip for your iPhone. It isn't a "new camera", just a bundle, and they'll shim it for you.

Note that the Sony sensor used in the IQ250 back and in the 645Z does all A-D conversion on the sensor. So the "look" is baked in before PhaseOne got its hands on the sensor. The Pentax looks better every day.

Getting front-paged at DPR for this bundle twice: priceless.

Richard Shih: Bear in mind that the cost of just the back alone is suggested at 24,990 EUR / 34,990 USD, plus the body and lens. Winning the contest and getting a loaner would probably be the only way most people would ever get to work with technology like this.

The 645Z uses the same Sony sensor. And given that it is an Exmor sensor, the "look" is already baked in before the raw image leaves the sensor in digital form. Very little in the way of image craft comes from Phase One in this camera.

"Stellar II is a unique object of repulsion. It blends eye-offending vanity with exceptional arrogance and comes with the latest unapologetic pretensions..."

I hope I typed that quote correctly...I just woke up, so there might be a few typos in there.

On Canon EOS 7D Mark II First Impressions Review preview (2709 comments in total)
In reply to:

Marko Nara: So much potential... wasted.

I dont comment much in Dpreview... but if Canon can Read this, please do.

Got to admit that im disapointed to see the Specs of the 7Dmk2. I was truly hoping that it will house a brand new Image Sensor with better performance to the APS-C lineup, and by performance I mean "Hardware Performance", not via Software Digic 6 Procesors.

Canon should listen a little to his costumers. AF and Burst are cool, but the true power comes in the IQ department, where its needed most also.

Nobody wants a camera of 2014, that cost 1800USD, with the image quality of a 400USD camera from the 2010.

I know that must be hard to make a New Sensor, but its not imposible, because other Brands have already done that.

GL!

We'll see if this "new" sensor can produce more than two stops less DR than its competition without prodigious pattern noise. I know that isn't important to everyone (e.g., "slide shooters"), but it is important to a lot of users.

In reply to:

Donnie G: I'm surprised at the number of armchair camera designers here who are so upset with Canon for not turning its excellent pro-grade, deliberately built for action photography, APS-C camera into just another consumer grade, jack of all trades, wannabe pro pretender. Meanwhile, the real camera designers and engineers at Canon will again be laughing all the way to the bank as the EOS 7DII proves once again to be the only true professional level APS-C interchangeable lens camera system in existence, today, tomorrow, and into the foreseeable future. :)

The Samsung NX-1 comes to mind. I'll be watching keenly for tests of this camera. On paper, it's everything this camera should have been. In practice, well, we'll see. But either way, Samsung gives us an idea of what it means to "swing for the fences" in this market sector.

Paul Guba: Misleading headline at best. Similar camera has been made for years and is mirrorless the same way a view camera is. Like saying Sinar is now making a mirrorless view camera. Truth its: Phase-Alpha-Rodenstock bundle.

EXACTLY RIGHT!

In reply to:

Anastigmat: A good idea the implementation of which has been long overdue. The medium format mirror box is a big obstacle to portability. It is bulky, heavy and it adds vibration by the truck load. Replacing it with an electronic finder makes even more sense than doing the same for35mm FF or APS-C size sensors. Next we may see medium format cameras with a collapsible bellows lens that can be used for street photography.

It's a technical camera setup made out of stock components that have been available for some time, being sold as a bundle with a little iPhone cradle. They'll shim the mount for you. This is not a new camera. People have been using this setup for years.

In reply to:

DavidsfotosDotCom: Whats the dynamic range & bit depth? Should be waterproof for that price.

The 50MP CMOS (A250) sensor is an Exmor with 15 stops of dynamic range.

Worth noting that this same sensor is available in the Pentax 645Z for under $10k complete.

These are existing backs in a technical camera configuration that has been out there for a long time. It's nothing more than a bundle. Not a new camera at all, or a new concept.

This is not a new camera. It is basically a bundle of components for an existing and often-used technical camera setup, with a little slot to put your iPhone.

The dealer will shim your camera-back combination to assure alignment, but this is something you needed to do anyway.

On Samsung NX1 real-world sample images article (330 comments in total)
In reply to:

Miki Nemeth: The NX1 would be the 1st consumer camera with large-sensor (APS-C/FF) supporting in-body 4K video. I don't regard Canon 1DC, C500 and Sony FS7 as competitors. I wonder how the videography features are implemented: focus peaking, touch-to-magnify, for example, in video mode.

Remember that each 4K frame is derived from a full 28MP sensor readout in this camera. The samples at full HD are the best 1080 I've ever seen out of any camera to date. As far as videography support features, we'll have to wait and see.

In reply to:

tinternaut: At this pixel density, I think there is one simple/important question: do the extra pixels confer an advantage that outweighs the inevitable extra noise?

Noise is measured /per unit area of the sensor/, so extra noise is by no means inevitable with more pixels.

Well this surely won't attract negative comments!

And who wouldn't elect to use one of the softest metals in the universe to make a camera?

Jogger: The 60 concept is cool and will sell out. But, the central ISO dial on the back is stupid.

When you shoot film, you really do need a reminder of what kind of film you have in the camera at the moment. It is easy to forget when you put down the camera for a few days and then pick it up again You can't open up the camera and look.

In reply to:

(unknown member): Is there a Reason why the fresh Nikon D4S has less DR as a 6 Years old FinePix S5 Pro ?

It doesn't. Go see DxOmark for RAW DR.

In reply to:

Sad Joe: So the D4s is slighly better than a 3 year old Canon 5d3 which sells for well under 1/2 price - wow - must change all my kit - NOT. Guys don't be suckered - BOTH Canon & Nikon could bring out VASTLY better cameras for the same or less money - but won't as they wish to DRIP FEED us improvements and get us to keep updating our kit. Only fools with money to burn follow their lead - and don't give me the 'pros update all the time to stay ahead'. Rubbish - real - I have to make money - pro's are VERY careful about spending money….

Yes, I like to shoot in dark places where nobody else is able to shoot. The darker it is, the less people think you're actually taking pictures of any meaningful sort. You can get people in unguarded moments even when they know you're taking their picture. Try it. Every time Nikon improves their low light response, I find new things to do. Think I'll keep the D4 til the D5 comes out this time around.

I've done album covers at ISO25k. They look great. These are just shots
