snapa: Question... would this work on a laptop or desktop without a special high end graphics card to feed it the video required for optimal usage? I think they (DPR) should have put a disclaimer in the article referring to what type of video cards would be needed for this type of monitor. There are people who may not know about all the hardware needed for these high tech monitors to run properly.

Sure. Here it gets complicated.

You can get a card with DP 1.2 or higher or HDMI 2.0 for under 130€. A GeForce 1050 or Quadro P400 would be sufficient. And you don't even need a card. There are many mainboards with DP 1.2, so you can use the on-chip graphic of the CPU.

One with a HDMI 2.0 or DisplayPort 1.2 port.

villagranvicent: Well, besides the Leica Cine lenses they are a bargain indeed:

https://www.bhphotovideo.com/c/product/1233351-REG/leica_lei_smlx_c_set_10_summilux_c_10_lens_set.html

It is a lens for broadcast application. This lens in action would look something like this:

jim seekers: I know that this is a FF camera, but does it have less noise than the RX100V which only has a 1" Sensor, many years appart with advanses in sensor technology, just wondering how both compair with noise at various ISO settings.

Lets compare the output!
Take the Studio shot comparison tool and take a look at th RX100 and the A7SII and two other cameras and set the image size to print (compare is broken and sets the size to "print"). This is important! Lets see... The RX100 was shot at 19mm/4 with 1/1250s at ISO 1600. The A7SII was shot with 55mm/5.6 with 1/640s at ISO 1600. This is very different. The smaller camera was shot with much greater DoF (much smaller absolute aperture). To get the same exposure we have to set the A7sII to ISO 12800 where it was shot with 1/5000s. Now we have aproximatly the same exposure. And the output is comparable, virtually the same. I put also in the Nikon D5 and the A7RII. Their results are comparable to the A7SII also.

Take the same picture. Same DoF, brightness, exposure time. (Same scene, lighting, angle of view, etc. of course.) Then compare.

maxnimo: So is this better than using 5 inch floppies? I'm skeptical.

Yes I remember Iomega Jaz. What a rubbish! There were also SyQuest. Also Rubbish. I also had QIC tape. One QIC-EX cassette could store 400MB, wich was about 4 times more than my hard drive at that time. And it was slow. Very slow.

tkbslc: I hope nobody buys this expensive drive for image storage. There's very little real world difference between an SSD and a HDD for viewing and editing images.

@Scottelly: I have no idea what he is talking about, but I think thas is just what you are looking for:

The Iomega Zip drive will replace floppies anytime soon.

DavidsfotosDotCom: The future has arrived, 2 years behind the technology!

I purchased a 128GB USB memory stick recently. 128GB is about the size of my SSD inside my desktop computer (it is a tower beside my desk actually). And it was cheaper than the SSD. Both are flash memory drives but the SSD is of course much faster. Flash memory is common in everyday use for years now. It is just the size and speed wich seperates them from conventional portable HDDs.

kreislauf: Hehehe, modular PC user here. I never understood the need for fancy optics when you have to pay large for it...
For that price, I built a water cooled PC with similar specs and much longer duty time...

But the Mac has two cards. And the blowers are pretty loud when the cards are really working. That is because the coolers are restricted in height. The ones that not blow out are less loud, but the heat stayes in the case and it is trickie to prevent it to be used for cooling the cpu and psu. There are better designs than ATX to prevent that.

But you compare CPU cooling. I have a Noctua NH12 wich is very silent even on heavy loads on a 95W TDP CPU and is acceptable loud on a 125W TDP CPU. CPU cooling es very effincient with those big tower coolers and is not the issue with the ATX design. The video cards are the issue. No one had 250W cards wich use two slots in mind when they desingned the ATX standard. The problem is this: Where does the fresh air come from, where does it go? How is it pushed thrue the cooler?

zodiacfml: From a PC person perspective, the issue is with Apple reluctant to upgrade the video cards because it will require a custom design and hardware for such a low volume product (in comparison to their other products).
Now, they are wishing for a new Mac Pro design where it can take PC parts for upgrades without trouble or attention required from them.

But it has to fit in the case. They will need a costom layout for the board.

@PeterOlsen: So why did apple put two cards in the mac pro?
Image editing is not the only thing the mac pro is for. There are many applications wich benefit from more cards when a more powerfull single card is not available. Either for graphic power or for computational power. Also the second card does not have to be video adapter. It can be any card. As long it is big enough to block the video cards fans.

@Toselli: In my computer, which is air cooled, the loudest source of noise is still the HDD. But I don't have a realy big video card, let alone two or more of them. What makes so much noise in your water cooled system? Is it the pump, the fans on the radiator, the flow of water in the cooling blocks and hoses? The pump can be very quite and the radiator can, if big enough, be fanless.
Air cooling could be very quite even with high power components, but the ATX form faktor is not a very good solution for that.

You need it if you want to keep it quiet. If you put many cards with high power consumption in an ATX case it will get loud. Also there is just not enough space for proper cooling. One card gest in the way of the card next to it. Like here:

not very clever

The design was not completely stupid. The usual ATX design has many shortcomings related to te cooling. The design of the mac pro eliminates the need of water cooling. But it was clear from the beginning, that its biggest disadvantage would be the inability to upgrade and expand. And it is to small also. The Heatspreader can not dissipate all the heat the mac pro produces. A little bit larger and the problem would not be there.
I don't have or use one.

iAPX: So sad this confusion between Nyquist frequency, that clearly state the highest resolution that could be obtained, and the ability to have clear representation of lower resolutions.

For example in 1D, having 4000 pixels enables to represent 2000 pairs, but won't be able to correctly represent 1900 paris, in fact quality will be degraded overs 1400 pairs, and will be perfect at exactly 2000 pairs.

Maximum representable resolutions <> All inferior resolutions will be correctly represented!

@mosc: But on a 2160 lines TV they both would look good, because 2160 is a integer multiple of both.

TheWhiteDog: Still using the Spyder 4 Elite, it still works great. Hopefully this new one can use USB 3.0 ports, mine needs 2.0 and that is a pain as my monitor ports are all 3.0 and the only 2.0 ports on the computer are on the back and one has to unplug the "Spyder" when they update- which is why I have yet to install the latest update for the Spyder 4 Elite. Other than that, it works fine.

This is the first time I hear about incompatability of such kind.
