"my guess is that manufacturers are upscaling their design so they also fit (or almost fit) 44x33 sensors."

wrong guess. It got nothing to do with bigger formats. What manufacturers are doing is upscaling their lenses so in a FF camera, instead of having to deal with heavy corrections of vignetting, distorsion, smearing, etc in the corners, you use the "sweet spot" of the lens, even on a FF camera. Pretty much like how FF lenses perform better on APS-C cameras by using the center section of the image circle.

Me every single time when I see that Leica announces a new product

-Skips the whole article just to find out the price.-

I mean, I can't do anything else aside from commenting or saying to myself, oh, that's nice.

Bassman2003: I tried this camera for a short while at a Sony event and I just could not get past the ergonomics. Without the grip attached it just did not feel comfortable in my hands. Seemed like an a6300 only a little larger. Great camera but I don't think I can ever get past the nice grip of my 5D III (or DSLR sized camera).

Also was expecting to be knocked over by the viewfinder and I thought it just looked ok compared to my pro video cameras. Still some room for improvement in this area imho. Yes they cost more but feedback is feedback.

I was entertaining a switch to Sony but not yet. The 24-105 f4 looks like a great lens. What the Canon version II should have been! Great to see so much tech in the cameras and the march forward.

A99II has similar specs in a larger body.

Burnt to a Crisp: Wow! 10fps, pixel-shift, IBIS, wifi+NFC--the A7R III really leaves the D850 in the dust.

A well-deserved 90% Gold Award!

A99II left the D850 in the dust, a year ago.

Interesting to find that they compare this camera to D850 but not to Sony own a99II which had similar specs, wait for it, a year ago.

mosc: I wonder if they'll take the sensor down-market at all, if they even can. The big design costs in an entirely new system should fade. Is it possible we'll get a <$5,000 MF body? Canon and Nikon do still sell FF cameras at more than that price.

Canon and Nikon sell those cameras above 5k USD because those are top of the line DSLR models. You cannot compare the specs of those cameras directly to the usual MF cameras because they're different.

lotzi: As with many people here, I find that this news about using photojournalism-class, off-the-shelf cameras and lenses for taking pictures on the space station is more a public relations move. Price is irrelevant in a situation where the cost of sending cargo to the space station is in the $20,000 / pound range.

JAXA also uses off-the shelf cameras for their space projects and then they put it into their modules. Look at the a7SII with a FE 28-135 F4 G OSS being used in their space module.

net1994: For gear heads, this is cool. For US taxpayers, not so sure. Why is the govt spending $65k for new cameras? Whats wrong with the ones they have now? Seems like a bit of a waste here. Sorry to throw a wet blanket here. Carry on....

You're going to complaint about cameras for scientific purposes when there are other things more costly to the U.S. government that are truly a waste?

I mean, if you're going to space, you need to go with the latest equipment to make it worthy, no?

NickyB66: Maybe Nikon gave nasa the cameras, great pr for Nikon IMOH.

Last time I checked, when you say that someone has ordered something, or that someone has placed an order for something, it means a buyout. Not a gift.

Sony cameras has been doing this since 2010. Yes, no blackout, but what you see is simply a slideshow.

In reply to:

Rooru S: DPreview should mention that at 10fps, what you see is just a slide show of pictures taken. There is a lot of people in the comments praising this camera for not showing blackout when it is simply showing the picture taken, not what the sensor is currently seeing.

It is basically working in the same way that old cameras has worked before, including the a99II that also has 42Mpx but shoots at 12fps while showing a slideshow unless you lower the speed to 8fps, which then shows a simulated blackout (I believe the a6300 introduced this feature).

@LDunn1

i have been using Sony equipment since 2010, and the 10fps burst in the a7RIII still shows the same kind of behavior as other cameras from Sony with the exception being the a9.

Yes, there is no blackout, but that's because the camera is showing you a slideshow of pictures taken, not what the sensor is seeing in real time. Look at the video and notice how the movement of the model drops in frame rate compared to after the burst ends.

The a7R III isn't a true move forward in terms of performance, because the a99 II already did just as good as the a7R III, a year ago.

I'm quite sure we won't see any SonyZeiss glass from now on. All of them will be Sony, Sony G or Sony GM.

brycesteiner: Not for the new Sony?

The main reason why Zeiss offers AF lenses for E-mount is because Sony opened up the mount standards back then in 2010 or 2011 for third party suppliers.

Related to A-mount, Sony made the designs, submitted them to Zeiss, of course following Zeiss designs and standards, and if they're approved, they will grant Sony their right to stamp those lenses with the Zeiss badge. And I assume they had to pay royalties to Zeiss for using the badge (which could explain why Sony has stopped designing more Zeiss lenses and practically everything is GM or G-branded.

They had to build a reputation for themselves which they got now.

In reply to:

Rooru S: Why haven't they made this lens available for Sony mount? At 800USD, I can see plenty of A68, A77II and A99II users getting one of these.

Has Sony sold their shares at Tamron?

@davev8: what are you talking about is new sales only. Which in photography world doesn't mean everything, because there are people that keeps their camera and lenses far beyond the usual recycle period from manufacturers.

What about users that already have a camera? Of course the japanese website that you mention (which btw, is BCNranking) only measures how much vendors get to sell in a year per brand. This is a more complicated subject, because Sigma and Tamron sales in BCNranking doesn't differentiate mounts.

Sadly, getting the Sony A9 is probably the only good way to track a subject at high speed. With the rest of mirrorless and SLT cameras from Sony is more like trying to predict where the subject might end rather than actually following the subject.

BobORama: Cool animation. Wrong conclusion. Obviously if someone with a sub $1000 drone can shutdown an airport, endanger passengers by piling up planes which increases the potential for disaster, its not irresponsible drone operators we need to worry about - its malicious drone operators. A mechanical means is needed as it is easy to "enhance" consumer grade drones to operate entirely autonomously.

@Roland Karlsson

random idiot flying a drone near airports it's a real deal. Even a light airplane flying near a big airport without authorization or radio contact demands moving traffic around, simply because you don't know what might happen. You don't wait for something to happen to do something about it. That's why there are tons of protocols, regulations and rules in aviation.

Your logic doesn't work in aviation. We don't take chances unnecessarily, because if we do, accidents might happen.

Random Idiot with a drone flying near an airport is dangerous.

absquatulate: You know those old film era prime lenses you've got stashed in a draw? they've just increased in value.

living under a rock I guess???

Since mirrorless cameras started showing up, people have been adapting old lenses massively (At least more than when people adapted Canon FD lenses on Canon EF cameras).

Then, speedboosters appeared almost at the same time as Fullframe mirrorless cameras. That truly increased the appeal of using old lenses because you were getting the intended FOV and DOF.

Finally, adapters that enable AF to manual focus-only lenses is the last thing that truly increased value of old lenses, because you could enjoy fairly fast AF with modern mirrorless cameras.

This new product changes nothing compared to all those things I mentioned before.

@Roland Karlsson
I disagree that random idiots are not dangerous. Any idiot by default is dangerous. Add a drone, and it can lead to costly damages.

A few weeks ago, a U.S. Army helicopter collided with a DJI Phantom, and there were some damages and debris found in main rotor and main rotor axle bay compartment. A dent, or chip can lead to a microscopical crack that after some time, specially in a piece subjected to centrifugal forces like a main rotor, can lead to critical structural damage which may result in a deadly crash. But how do you know that the drone didn't actually created real damage?

Just having to ground a multi-million helicopter for inspection cost money. Add non-destructive testing, man-power to open inspection panels to look for further debris, and now we're talking about thousands of USD in damages, even if it was non-threatening at first.

Now imagine aircraft landing at 250Km/h. Drones are a hazard for aviation, pretty much like how birds has been for decades.
