The press release and some comments sound like this is the first workstation that can handle a lot of RAM. Now Z820 (2 generations older than this one) can take up to 512GB. Z840 up to 1TB. I think that's plenty already. Especially given that these 3TB are just theoretical at the moment as there are no RAM modules big enough on the market to make it happen.
Have used the Z420/Z440 at work and it was great. For photographers its probably the best one (single processor). The bigger ones main selling point is the increased number of PCI slots IMO - allows you to connect more monitors.
For using this as a virtualization server however - 2 processors are always a nice thing to have. To max out the specs you need probably way over 50k though.

lesnapanda: Unless of course you're flying from/to a country that does not allow camera equipment to be taken on board. In which case your advise is equal to "don't fly at all" - not very practical.

Besides - the damage looks like someone did it on purpose. Unless it was in a plastic grocery bad without any protection whatsoever, this would require a massive hit directly on the lens. Certainly beyond the usual throwing around of bags you'd expect on an airport.

Yes, although UK have similar regulations. Might be you could have lenses with you and only check in your camera, since this was related to electronic equipment.

A 5k$ A7SII rig vs the 50k$ RED would a far more entertaining (and useful) comparison.

How on earth are they going to deliver a lend with 1:8 magnification ratio at the given minimum focus distance?

On article Sigma SD Quattro H Review (640 comments in total)
In reply to:

GEONYC: Since the review says the Sigma H is best at 100ISO, what about a couple at 200ISO so I can see for myself... and, what about a comment for us guys that shoot with flash fill 80% of the time.

As a comment: I can't wait until this sensor is put into something like a, Sigma DP0 ll, which could be a 14mm=21mm, fixed lens... at $1,500. The DPO is now selling at under $900. It is considered to be a 21mm lens with a free camera.

just out of curiosity - have you tried the DP0 and ran into limitations due to insufficient resolution? At 300dpi it's a 20x30 inch print.

User7228819398: Is an adapter available to use Nikon F or CanonMount Sigma lenses or do you have to buy a new lens set?

no adapter; you can however change the lens mount on Sigma lenses (Sigma offers this kind of service). Though it might not be a cheap option

In reply to:

Graham Gibson: I agree with the overall sentiment of the review, but the image tests really leave a lot to be desired from a comparison standpoint. The RAW DNG processed images look terrible, like they were just using full default settings. Just compare the results to the JPEGs to see the real Quattro image quality. Clearly better results should be possible from the DNGs (and I have seen such from other sources).

Additionally, as others have pointed out, it would be hugely helpful to include X3F and X3I (SFD) shots of the same scene processed through Sigma's own software to compare to the DNG RAWs. Everyone interested in this camera is going to want to know which file format to choose and how the output of each workflow compares. You include a whole review section comparing X3F and DNG, so why not show us the accompanying studio scene?

@Noah - if you're happy with how the image looks then yes. If you need to make serious adjustments, I would disagree. Personally I find the possibility to adjust the image in SPP before exporting to TIFF for further processing (if needed) valuable. For me - SPP fill light is a great tool which results I'm not able to reproduce in Lightroom (though I'm not very good at LR edits). ALso - SPP is needed anyway for the super fine detail mode. Which is really fantastic for some situations.

In reply to:

supersonic: Something not mentioned:

The full length SLR lens mount includes room for a separate IR block filter, spaced far away from the sensor.

Dust falling on it is not visible.

And it can be clicked out, for cleaning, or better still IR/visible monochrome photography.

Edit: I'd also be interested to know how it responds to UV.

I don't have one, but very interested in using one as a true monochrome camera. Not "B+W conversions" from a Bayer sensor.

See here for details: https://www.ephotozine.com/article/sigma-sd-quattro-h-review-30496

@HowaboutRaw - while I have not tried very hard to do this on the quattro sensor from Sigma, on Merrill you could shoot at much higher ISOs monochrome than you could in colour using only the top layer of the image. Also - comparing Leica to Sigma is a little like apples to oranges, don't you think?

In reply to:

User9362470513: "Removing the Bayer color filter array removes the slight blurring effect of demosaicing while also allowing around 1EV of extra light to reach the sensor."

Or you could use a Foveon sensor ;o)

@kpaddler - I am well aware of what PhaseOne is and what kind of Clients they are targeting. The original comment from User9... was about foveon sensors having the same quality as quoted (no blurring from demosaicing/interpolation occuring in bayer sensors). Not about what kind of quality you can achieve overall as compared with PhaseOne.
As such I see this as a valid comment, pointing out that sensors allowing such pixel level sharpness are available to amateurs. Just like 35mm film will not compete with 8x10 - Sigma (or Leica Monochrome) will never be able to compete with this PhaseOne back. But that has not been suggested by anyone.

kpaddler- I highly doubt the comment suggested the sigma sensor as an alternative to this particular digital back. Rather pointing out that such an effect is achievable with sensors available to amateurs.

Ab Latchin: While I am not sure what the costs are for a camera like this, it would be nice for all makers to offer this option in a popular body.

@User3397462960 - Dolphins, Eskimos, Who cares? ;-) Plus- the press release discusses both back and a kit (=camera).

kpaddler - why this comment? I routinelly use foveon sensor output from the top layer only for B&W work (especially under difficult light conditions). In such a setup it is a true b&w camera. Yes - the sensor characteristic is slightly different than, say leica monochrome, but that does not really matter here.

On article 2017 Roundup: Fixed Prime Lens Cameras (467 comments in total)
In reply to:

GDMitchell: The problem with all of these cameras is one thing alone. They are fearfully over priced and don't represent good value for money. Why anyone would pay over $1000 for any of these, unless money is no object to then, is beyond me. each one represents a massive compromise in that they attempt to fit a really high technical spec into a smallish case and really represent poor value for money. The large apsc sensors are welcome but 2.8 equivallent is not impressive. They weigh in quite highly too meaning that even though some fit in your pocket you really wouldnt want to carry them that way, maybe the Ricoh being the exception there. Too much development is being wasted on gimmicks when faster lenses would be more useful. I read about micro 4/3rd standard being possibly dead. If people are wasting money on these overpriced point and shoot models, then that could be true, but really there is so much good gear out there already, all formats could become obsolete unless we all realise an expensive camera alone doesn't produce a good shot.

Some of these cost less than an equivalend quality lens alone. So I'd say there is some reason for considering buying them.

uhoh07: Another bizarre roundup. LOL

Let's see the RX1rii untouchable in image quality, legendary among pros, and is actually in many pro bags, but Fuji is spending more ad money at DPI?

OK the Fuji is probably more fun to use and does fine. But cmon.

Actually the Sigma lineup would have the best IQ as long as ISO100-200 can be maintained.

Old Cameras: I'm starting a Kickstarter campaign for an exciting new product.
It's called "QuadLens".
You can carry FOUR lenses on a revolving hip holster.
You heard it here first.
It's rated to 200kg, ideal for super telephoto lenses. The first 100 backers will receive a free one year supply of my new "6 Hour Energy" drink.

does it come with free hip replacement surgery?

Tom K.: "...a belt-worn device that is made of steel and fiber-reinforced nylon and can carry up to 100kg weight."

220 lb of lenses. If that's not a case for NOT using an ILC I don't know what is.

you can carry all 3 of your sigma 200-50 f/2.8 lenses and still have 50kg left. Awsome! :)

On article Fujifilm GFX 50S vs Pentax 645Z vs Hasselblad X1D (348 comments in total)

The fact alone that the Pentax 645Z which was launched so long ago is still on par with the newly lauched contenders from Fujifilm and Hasselblad shows what a great piece of equipment it is. The one thing that the Pentax is not is portable. You won't be shooting that on a sunday walk in the park with your dog or at a lunch with friends. Or shoot a MF selfie without a tripod ;)
