I don't know how much DPR normally asks for "sponsored" content. But $800 sounds reasonable to me. And its not even sponsored ;)

Now with China though, it's a different thing ...

On article GIMP seeks funding for future advanced features (86 comments in total)

This further blurs the line between open source and commercial software. Many open source projects are or have been heavily funded by a few supporting companies. I think this is a good thing if it is open source in the end (adding to the code base of mankind) but maybe not so much if it leads to freeware with cumbersome license models and awfully distorting the market forces for all the small software companies out there.

Consider that e.g., Affinity had to be created in a squeeze between the monopole (Photoshop) and the free (Gimp). And it isn't clear yet if it has succeeded at that. In an ironic way, freeware protects the big players in the software industry by keeping small players out of business.

nir-vana: Equivalent apertures are slower than what you can buy for FF cameras. So what's the benefits of this so called "medium format"
63/2.8 equals to FF50/2.2
For the A7RII I can choose f/1.4 and even f/0.95 lenses.

The base iso of the D810 is real (measured to be ISO 50 actually). It has a much deeper full well capacity than the D800 or any other full frame sensor. The sensor is a lot more expensive to manufacture and e.g., Sony isn't using it in any of their models. Therefore, the total sensor's well capacity is only matched by MF sensors with a native iso 100 or better, like Pentax or Fuji. Resolution aside (7360 vs. 8256 px width) and assuming top glass and identical color profiles there is physically no way to tell images from the two cameras apart.

Nikon ordered this medium format like FF sensor from Sony after seeing how MF photographers started to embrace the D800E, a camera's success which Nikon did not anticipate. IMHO though, the D810's most discerning feature (its MF like equivalent base iso) was grossly underrated by the media such as DPR and is measured but not scored by DxO (max SNR).

This "cleaner" rendering from the larger sensor is real. It is an effect of a lower equivalent base iso of the larger sensor. However, it is cancelled by the D810 base iso 64 which is unparalleld in the MF world. One of a few things I am trying to tell you ...

StephanBG: Wow, love DP, same people who played up the difference between APSC and FF now downplay the difference between FF and MF.

I don't think this is what is happening.
An ISO 64 F1.4 full frame camera would be matched by an ISO 25 F0.9 APSC camera which does not (yet) exist.
An ISO 100 F2 33x44 MF camera would be matched by an ISO 62 F1.6 full frame camera which does already exist.
And I think that's the whole point people are trying to make.

There is no such law as less enlargement = better quality. This used to be true with a given film emulsion only. The dependency of quality on enlargement is more complex and includes base iso and optical lens performance. I studied this in detail and published results years ago.

@marc,
I agree for the 3D look and that lenses have the bigger impact. However, this 3D pop is a result of micro and macro contrast and a question of proper post processing (provided good enough quality in the first place). The standard D8x0 profiles are not very good for landscape or portrait.
Foveon has an advantage in color resolution similiar to the effect if pixel shift wirh a K-1. The effect is there but it isn't huge.

@OlyPent
Sensor sizes lead to options (in the equivalent parameter space of focal, aperture and base iso). With larger sizes leading to more options. This is true up to full frame but doesn't hold true anymore for the current breed of cropped medium format. This is why you're wrong, or at least wrong today. I wish it were different. And I am not even talking prices yet ...

@marc, nice video from TCS and good performance. But you somehow miss what the magic of medium format is about. We're not (only) talking resolution here.

An ISO 50 full frame with excellent glass (e.g. D810 with Otus) will render a scene medium-format like, or better. This isn't film and this isn't true medium format.

The artistic restriction to F1.6/2.2 primes and F3.2 zooms (equiv.) with the Fuji is real. For true medium format cameras this is less of a concern, but the Fuji only has a 0.79 crop and is rather close to full frame to start with.

ybizzle: I would hope the high end smartphones of the future would utilize the 1" sensor which should have become the norm since the Panasonic CM-1 was released 2yrs ago. One can only dream...

I took folded optics into account. Consider that a 45 degree mirror would just fit a smartphone's slim housing for a small sensor and aperture.

Even with dual cameras in phone and tablet, plus a notebook webcam and an action camera, all these sensors combined are still only a fraction (1/7) of a full frame's sensor's surface area. Probably less than 1/10 taking yield factors into account.

The high end photography market isn't to be dismissed, esp. with its higher margin.

This isn't physically possible (in anything slimmer than 15mm).
But camera arrays are and arrays can simulate larger sensor cameras.

Funny thing is,
in their latest Instagram video (linked from https://www.facebook.com/Fotodiox ) Fotodiox mounts a PENTAX-M 50mm 1:2 lens without a mention of E mount ;)

nokinonacynos: DxO places a lot of weight on colour depth. Something that can be only tested and not discerned under normal viewing. DR and noise should be given more weighting.

@nokinonacynos
This is a common misconception.
DxO measures and weights color depth as a means to benchmark a camera's color performance overall. The other scores are all luminosity scores.
Wouldn't DxO do what they do, a monochrome camera, or a camera with a ridiculuously weak CFA (resulting in strong color noise) would have too high a score.

Overall, too few people really understand what DxO does and why.

Summary: a good DxO portrait score is a sign of low color noise in shadows.

Biological_Viewfinder: The case should be thrown out of court for being frivolous. I don't care what happened; she's asking for $2.2 Billion and therefore the case should be dismissed on the basis of it being frivolous. It's stupid and I'm tired of the games. If there's ZERO chance she could get $2.2 Billion; then drop the case until she gets reasonable.

Secondly, why is the restaurant being sued? Wasn't it the photographer who did the actual "damage"? Sue the person not the deep pockets. Again, frivolous and needs to be dropped. If anything, she should be fined for bothering the public with her nonsense.

The irony in the McDonald's case is that the victim first approached McDonald's off-court asking for a $20k settlement.

Here in photo rights case where no physical damage was caused, the "victim" goes straight ahead to ask for $2.2bn. That's a new record for https://en.wikipedia.org/wiki/Frivolous_litigation

@stevo23
The McDonald's case is pretty famous and all known in the public this far was that it settled for less than $600k. Your less than $300k figure is new information. Would you mind being cited on this? Or is this confidential information?

The medical cost were $13k plus $5k care by her daughter. It was said in public that the amount paid was sufficient to pay a live-in nurse until the victims death in 2004.

Andrew Butterfield: Back to analog... well, they sold 30 million vinyl records last year. But there were 45 billion songs downloaded or streamed. So analogue is potentially a reasonable sort of a business, but stil a relatively small one and likely a temporary one too because of format boredom and reality setting in...

@Dragonrider, you got my point, almost.
My point was, media produced for car listening are more low dynamic range than media produced for the listening room.
