Jonathan Mac: Sony have a lot of work ahead of them if they want to dominate the camera market. First and foremost they need to make drastic changes to their lens line-up: an increase in variety and quality while cutting prices, in both FF and APS-C. Essentially they would need to compete with Fujifilm in this regard.

The A7 lacks in-camera raw processing, a basic feature in cameras for at least ten years now.

IQ problems from overly-compressing raw to weird stripes on images continue to make a lot of people wary of their products.

I've also read numerous comments on the build quality of the A7 cameras, that they are not what people expect when paying that kind of money.

Three years to become top dog? I wouldn't put money on it.

I have to disagree on the lens lineup. Sure, I'd love it if Sony cut all their prices by 20% tomorrow, but they're actually priced in-line with similar designs from Nikon and Canon. It's easy to make the mistake of comparing a recent Sony design with an older design from a competitor since most of Sony's lineup is new right now.

While Sony is certainly missing a few things from their lens lineup still, I'd say it's at least a year too late to claim they have major holes or really need to step things up. Have you been paying attention to the sheer number of lenses Sony released in the last year alone?

RAW processing is certainly still a sticking point. I still can't fathom why Sony still doesn't have a *lossless* compressed RAW option, like their competitors have for years. Sounds kind of like someone in management just can't back down on their flawed idea of what the RAW feature set should be on the kind of camera they're selling, and everyone suffers as a result.

chaos215bar2: I'm confused. Two 4k sensors only gives you half 8k resolution. If this is producing 4 view 3D video, you're also further sacrificing resolution to capture multiple points of view, capture information about the incoming angle of light rays at each pixel, or some combination thereof. (Under optimal circumstances, wouldn't you be dividing your total resolution by at least 4, meaning that with two 4k sensors, you get at most half 4k resolution per view?)

In what sense is this camera 8k?

Even if so, you'd need 4k x 240 fps minimum with 2 sensors to capture the amount of information represented in an 8k x 30 fps x 4 view stream. 8k is 4x the resolution of 4k, not 2x.

You can undoubtably approximate 8k x 30 fps x 4 views with less, since 8k gives you plenty of headroom before anyone is likely to notice the loss of detail, but you're still making up information that wasn't there to begin with.

This is nice, but I don't understand how a guide like this benefits from being a video. A nice, bulleted list with pictures and important points bolded and highlighted would be much better, from an informational perspective.

On article Video: How to pack for a two-month photo expedition (56 comments in total)

"Don’t by [sic] anything until it has been 100% required on multiple trips. Less gear, more time for travel and photography"

100% required for… Photo opportunities? Survival? What?

If a piece of gear were 100% required for a trip, then by definition that trip must have been a 100% failure without that piece of gear. Obviously there's a little more nuance here.

"And a camera capable of recording for 43,000 hours straight."

Kind of like a security camera?

jaykumarr: // the iPhone makers refused a licensing deal, suggesting Corephotonics patents could be infringed with little consequence//
Can someone tell me if the above means that Apple understood that it can have it for free because it can by pass using legal hole?

The paragraph that's from is a bit awkward. As I read it, this is a paraphrase of part of Corephotonics' claims, not something DPReview is stating as fact.

In reply to:

Roland Karlsson: What exactly do the Corephotonics patent claim?

I mean, you cannot patent having two cameras.

And you cannot (I hope) patent using two cameras and combine them to one virtual zoom lens. It is just too obvious.

There must be something more. Like some clever technique to do it.

So, what was the patent?

Sure, but the USPTO also errs heavily on the side of granting patents and leaving it up to the courts to sort out whether they're actually valid. They simply don't have the resources to do otherwise.

On article Crystal clear: Inside Nikon's Hikari Glass factory (93 comments in total)
In reply to:

nandbytes: Is it just me or is the slideshow not at all user friendly to navigate i.e. poorly designed.
It fine when the blurb under the picture is small but when its long I end up having to scroll back up to click next. Also 29 pages slideshow is a bit too long don't you think?

(before someone mentions it, yes I know mobile site doesn't have slideshows. I am not going to change devices just to read one article!)

Indeed, DPReview slideshows are super easy to read when you view them from an RSS reader and can just scroll down one page with each image in-line followed by its blurb. (I guess this is what the mobile site does too.)

Viewed in a browser, the format is indeed pretty cumbersome to read and doesn't seem to offer any obvious advantage over the in-line version.

Small nit: Annealing is definitely not going to be used to remove bubbles as suggested in the article. During annealing, glass is not brought to a temperature at which it even begins to flow, let alone the molten state you'd need to melt out a bubble. (If the glass were allowed to flow, you'd be casting, not annealing it.)

The last stage of this process at which there's any chance of removing a bubble would be while casting ingots. Even when the glass is heated for the press, it'll be about the consistency of very thick honey. Any bubbles at this point aren't going anywhere.

LessMirrored19: Last quarter earnings

Sony :

Nikon :

Sony has more funds for R&D than Nikon at this point. I think the culture at Sony is focused on "moving ahead" and the culture at Nikon is focused on "catching up".

Is this just Sony's camera division? Sony's R&D funds have to support a much more diverse product line than Nikon's.

mmarian: Can someone explain to me why are still people out there willing to pay 5 times more for 32" Eizo?? Is Eizo overpriced or is this Philips just not as good despite of all the on paper atractive specs?? Not trying to pick a fight just want to understand the difference..

Have you read the features or specs pages of Eizo's closest comparable monitor? https://www.eizo.com/products/coloredge/cg3145/

I'm not claiming Eizo's prices are justified or not, but all you have to do is look down the list of features this monitor doesn't have and specs it will never even bother stating to get an idea what you're paying for on the Eizo. It's designed and built for a completely different market.

"This new model is designed for gaming but is ideal for video production as well, due to its key selling point: the ability to rapidly and seamlessly handle 4K/UHD graphics."

What is "the ability to rapidly and seamlessly handle 4K/UHD graphics" actually supposed to mean in the context of gaming? Games are not streamed off of or rendered by the SSD, and literally any modern SSD is more than capable of handling compressed 4k H.265 video in real time.

Gaming is about short, intense bursts of data. (The more quickly you can read assets into memory, the shorter loading times will be.) Video editing requires sustained steaming of multiple video files, likely at a much higher bitrate than anything you'd distribute for consumption (i.e. that might be included as part of, say, a game's cinematic sequences).

This might be a good SSD for video editing (though theoretical maximum throughput tells us very little in that regard), but video editing and gaming are completely different use cases.

Never? *Never*?

If you're going to lead with a claim that a certain technology or capability will never, ever, in all of time, make it into consumer devices, you need to at least make it immediately apparent there's some basis to the claim. The title and introduction read like clickbait, making an extremely bold claim without backing it up in any way. Looks like an interesting article, but if this is way you're going to introduce it, how do I know the rest isn't going to be just as devoid of meaningful information?

This is pretty cool tech, assuming it works as advertised.

My main question, though, which I don't really see answered anywhere is whether this will suffer similar flight restrictions to DJI products. Any competitor that doesn't feel the need to dictate where, when, and how their products can be operated seems like a good thing to me.

To be clear, everyone should respect reasonable airspace restrictions (and I know of none that are anything but), but I'm not at all comfortable with a company maintaining the ability to remotely prevent me from using a product I purchased if it doesn't regularly check in and my use doesn't fall within what they currently deem allowable.

In reply to:

junk1: I wonder if phase based AF systems would work better than I assume they are using optical contrast detection...or maybe they are using phase detection?
13 cameras seems like overkill.

On-chip phase detect autofocus is pretty common these days. Not sure why you'd assume a $2,500 device doesn't have it. (To be clear, I wouldn't assume the R1 does use a sensor with phase detect autofocus, but it hardly seems unlikely.)

You should let Skydio know immediately, though, that 12 tracking cameras is overkill. I'm sure they'd love to know they'll be able to save some money by using fewer.

photographytragic: Why am I nodding in agreement about this ability to limit drones
- but just as uneasy about it too!

Simply not having the tools to perform a given action vs. being given the tools, but being told, essentially, "we don't trust you, our customer, to behave responsibly, so we're going to give you this tool, but enact restrictions on our own terms, without any possibility for you as an individual user to opt out, dictating what you can and cannot use it for", are two very different things.

Obviously private UAVs cannot be allowed to operate at this sort of event, and indeed local enforcement is difficult. But that doesn't mean DJI needs to implement these restrictions themselves. I suspect they only do so out of fear of their products being made illegal to operate entirely without cumbersome licenses, which is understandable, but at the same time sends a very clear message that when you buy a DJI product, DJI has the ultimate and final authority to dictate how and where it can be used. I think it's more than fair to question that.

Bing Chow: If convicted, the name and face should be made public. A criminal record + potential of hurting future employment should be sufficient for a stunt like this. There's plenty of toilets to clean in this world anyway. The law needs to send a message to wannabe social media stars.

I agree this person needs to be prosecuted to the full extent of the law, but at the same time it's disheartening to see that one of the most upvoted comments here is advocating for ruining someone's life over this. I can only hope there were at least as many people who would have down-voted this comment in the absence of the silly internet paradigm where the most polarizing opinions get the most attention, because no one can directly express disagreement.

Time served should be just that. How can we expect to actually reform anyone after destroying just about any chance they may have had of a normal life, once they're served out the duration of their punishment?

Surely it's not that hard to think of something you could use faster memory for. (Hint: It doesn't actually have to be 8k video capture. That's just one option.)
