dgumshu: Stripes, overheating, color and now blinking pixels? What else?

"Sony didn't meet their own spec. if it can't work above 30 Deg C, they should specify it..."

I'm sure the maximum temperature for which the manufacturer guarantees normal operation (40°C) was exceeded if the camera was used in direct sunlight. There's a reason why meteorologists don't place their termometers in direct sunlight, because that would make them much hotter than the air temperature.

AstroStan: Looks like many Sony bashers are not even bothering to read the article before spewing ignorant "don't buy" dictates.

"Prof. Dietz is repairing a fault in a product."

No, he's mitigating the effect, but it's up to Sony to fix the cause. Have you never created some kind of workaround or fix for a problem you've had with a product?

Even professors are free to do what they want in their spare time. And I don't think he did this as a favour to Sony, but for himself and other fellow Sony users.

vscd: The Fix? Use a different brand.

Canon's Dual Pixel sensors shouldn't be affected since they don't have any "masked" pixels. The older so called CMOS AF sensors could possibly be affected, though.

anticipation_of: The fact that all cameras don't simply record straight to DNG is lunacy. Who are the people who think this a good idea, and why? Just record to DNG, and stop it with the terrible in-house image processing software that nobody likes. It has to be actually costing these companies money to perpetuate their proprietary formats. I've literally never heard anyone make a case for this bloody-minded insistence on proprietary RAW files, even an unconvincing one. It's emblematic of the blinkered, hidebound thinking that plagues camera manufacturers.

"The nice thing about open standards is that the creator need not keep supporting it indefinitely. They've even expressed interest in turning it over to ISO."

I believe they already did. If I'm not mistaken, the latest version of the ISO standard raw file format is based on DNG. And I think that DNG originally was based on an older version of the ISO format.

"I don't why camera companies don't implement DNG more, but I would guess that it probably is more related to the reason why we have numerous redundant, closed, proprietary lens mounts, TTL flash hot shoes, wireless TTL flash protocols, batteries and even the odd proprietary USB connector still."

Yes, I believe it's about money. They don't want third-party software to be able to open and edit their files without the software developer paying a licensing fee (but, of course, many smaller developers just reverse engineer the file format).
I guess some of the smaller camera makers (eg. Casio, Leica, Ricoh, Pentax, Samsung) chose DNG, because some software developers may not have been willing to pay licensing fees to companies with such small market shares. Or perhaps these camera makers just didn't want to spend resources on developing their own proprietary format.

On article Nikon dominates World Press Photo 2018 camera breakdown (385 comments in total)
In reply to:

ttran88: Just shows you Canon's dominant market share is more the result of cheap bundles that end up in closets.

Of course, you can't be #1 in the overall market without selling the bulk of your products to the largest part of the market. That said, Canon is very likely the #1 seller in the pro market too.

On article Report: Chinese company Xiaomi may purchase GoPro (93 comments in total)
In reply to:

Mariano Pacifico: "The U.S. debt to China is $1.17 trillion as of January 2018. That's 19 percent of the $6.26 trillion in Treasury bills, notes, and bonds held by foreign countries. The rest of the $21 trillion national debt is owned by either the American people or by the U.S. government itself. "

GoPro is just loose change to China.

China really isn't a communist country in the traditional sense anymore. It's really a strange hybrid of authoritarian, central planning and a capitalistic market economy. I'd call it communism-on-paper.

endofoto: Fuji should produce FF cameras too in addition to MF. XT2 are expensive but large DOF of crop sensor will not satisfy wedding pros. They are not produced for birding which is the advantage of crop sensors bec of conversion factor. XPRO2 come on, what is pro about this cam? it is good very good, but with too large DOF for portraiture, too narrow view angle for landscapes.

"Fuji can easily erase Leica too."

I'm not so sure about that. Leica caters to a very specific niche, and has (seemingly) very loyal customers who perhaps value the brand at least as much as its products. Ironically, to compete in that niche market, I think that Fujifilm would have to raise their prices significantly.

The OP talks as if DoF is a property of the sensor:

"large DOF of crop sensor"
"too large DOF for portraiture, too narrow view angle for landscapes"

It has nothing to do with the sensor itself. At a specific subject distance, a lens with a specific FL and aperture projects an image with a certain DoF, and it does this even if it's not attached to a camera at all. You can attach it to any camera that allows it, and the DoF will be exactly the same. It's only when you change the settings, for example because you want the same angle of view on a camera with a different size sensor, that you also change the DoF as a result. So, the lesson is: use the correct lens and the correct settings, appropriate for the sensor size.

Yeah, if you can't shoot portraits with an APS-C camera (or m4/3 for that matter) because of too large DoF, then you're doing it wrong. Plenty of examples to see on the web of people doing it right, using the right lenses for the task.

winkalman: I'm not sure how much Canon, Nikon, and Sony are spending on marketing but I can pretty much guarantee some of that money would be better spent on good-faith efforts like this.

In marketing, it's all about how the consumer perceives your product, so from a marketing perspective, it's really a double-edged sword. Even though many appreciate this kind of post-launch support, there are many others who feel that Fujifilm releases incomplete or insufficiently tested cameras, in need of "fixing" by firmware updates that add things that should have been included at launch.

LightBug: Barney, can you please clarify what you mean by "reign" and "almost"? By what measure is the "reign" defined, is it market share or something else? "Almost" isn't very precise, when do you expect the DSLR "reign" to "actually" end?

I agree that the MILC "takeover" is not immediately imminent, unless something completely unexpected happens that can't be extrapolated from the statistics. Like the two big DSLR makers just deciding to stop DSLR production and going all mirrorless overnight. Not very likely, though.

On article Canon EOS M50 Review (1296 comments in total)
In reply to:

keeponkeepingon: "On top of that, the M50's crop factor in 4K is a whopping 2.7x (including the standard APS-C crop,) which means that the company's widest EF-M lens, the 11-22mm F4-5.6, is equivalent to 30-60mm F11-F15 equiv. in 4K. Thus, if you want to do any wide-angle video capture, 4K is out of the question"

For the record 30mm FF (or 27mm with the 10-18) is considered wide angle, but then it appears dpreview has not used either the 10-18 or 11-22 on the M50 (neither are in the sample gallery):

https://en.wikipedia.org/wiki/Wide-angle_lens

"Common wide-angle for a full-frame 35 mm camera are 35, 28, 24, 21, 20, 18 and 14 mm, the latter four being ultra-wide. Many of the lenses in this range will produce a more or less rectilinear image at the film plane, though some degree of barrel distortion is not uncommon here."

I agree. Perhaps DPR should rephrase their statement, and write "Substantial crop in 4K makes ultra wide-angle shooting nearly impossible" instead?

30mm may technically be wide angle, but I'm sure that when most people talk about wideangle photography, they have something wider in mind.

Also, if you want to use the digital IS, the crop factor is even larger than 2.7x, which really pushes you out of the wide angle territory.

I've seen selfie 4k video with the 11-22 and it was not too bad with two heads comfortably in the frame.

But then it looks like dpreview hasn't tried out the 11-22 on the M50 ? (there's not a single sample picture that does not use a kit lens), so how can you ding a camera on wide-angle when you have not taken a single picture with the platforms only native, well regarded UWA lens?

I really curious though, and I'm wondering if anyone with an M50 has tried: What's an 8mm fisheye like on the camera in 4K video mode? I'm guessing since you are only taking a crop out of the center of the frame it's not too fishy??????

That 11-22 mm becomes a 28-56 mm lens in 4k mode.

If you extrapolate from the CIPA global shipping statistics, you might arrive at an educated guess as to when DSLR shipments (and, probably, retail sales) will fall below mirrorless shipments:

2012
Compacts: 77.98m
DSLR: 16.20m
Mirrorless: 3.96m

2013
Compacts: 45.71m
DSLR: 13.83m
Mirrorless: 3.31m

2014
Compacts: 29.60m
DSLR: 10.55m
Mirrorless: 3.29m

2015
Compacts: 22.34m
DSLR: 9.71m
Mirrorless: 3.34m

2016
Compacts: 12.58m
DSLR: 8.45m
Mirrorless: 3.16m

2017
Compacts: 13.30m
DSLR: 7.60m
Mirrorless: 4.08m

As a side note, it's quite interesting that compacts still outnumber ILCs, although not by much.

NOWHITELENS: I have a question:
Why are mirrorless fans so keen to see Canon and Nikon to develop mirrorless cameras?
Are they not happy with their Sony camera?
And how come Canon and Nikon shooters never want Sony to develop a DSLR?

But it does need to power the image sensor constantly, as well as the EVF or LCD screen, because it's always in live view.

On article Blackmagic Design announces Pocket Cinema Camera 4K (406 comments in total)
In reply to:

DARKR00M: So, when I said the GH5S was overpriced technology that was not revolutionary, and barely evolutionary, some people thought it necessary to point out to me that the price reflected its specialty and unique place in the market.

Well, Blackmagic Design apparently agrees with me, as the rest of the industry collectively screams in their own head “W T F !!!”

I also would like to point out that, the Blackmagic Pocket Cinema Camera will also come with a full Studio version of De Vinci Resolve, as Panasonic still insists on charging $100 for V-Log...

I can’t tell you the number of people that justified it, including Panasonic reps...

Now between this new release and the A7III, just maybe, the rest the industry will get their s—- together in regards to pricing...

Quite often, though, it's actually true that you get what you pay for. I think it's too early to assume that BMD hasn't cut costs somewhere to make that aggressive price point possible. Camera testing will tell us if this has affected performance or quality in any significant way.
