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

Jon Stern: Thanks for the interesting tour.

I'm surprised to learn that Nikon manufactures their own glass, and I'm a little skeptical that it provides them with much benefit in 2018.

@peripheralfocus, I'm probably quite representative of Canon users in general! We try hard to ignore Nikon marketing.

Whoops! I completely misread that page. This makes more sense now.

However, I still question the business side of Nikon keeping this in house. Vertical integration can work well, up to the point of business disruption (as is happening today with cell phone cameras causing traditional camera sales to collapse).

@Barney, having worked extensively with Japanese companies, I disagree. They tend to stick with corporate traditions long after they provide a benefit.

The same sticking with it attitude can sometimes work to their advantage, but at other times it becomes a burden.

Twenty optical glass types may sound like a lot, but it pales next to Ohara's 130 and Schott's 120.

While making their own glass might appear to insulate them against external supply constraint factors, I suspect they still outsource supply of moldable glasses for aspheres. I don't see any evidence of them making the raw "ball lenses" that are used in the molding process for aspheric elements, unless that was in a different part of the building that wasn't shown to you.

Unless they mold their own aspheres (which I doubt, they probably buy from Hoya and AGC), it's going to be these elements that can impact their production capacity, and asphere supply is extremely tight right now.

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.

BobT3218 China has 647 billionaires (as of last year). That's 100 more than the USA.

I take it you've not worked with Chinese companies, nor traveled there and seen the personal wealth on display in the major cities.

I've spent quite a lot of time there. I find people are just looking to make money, and mostly ignore the politics. I've been to shopping malls that look just like high-end malls in the US and Europe, full of people weighed down with bags from brand stores.

As others have said. China is no longer a Communist country. It's a one-party state that suppresses political dissent, and violates many human rights, but it's not communism as Karl Marx would have thought it.

I think a new word is required to describe the Chinese system. Maybe in the future they'll call it Xiocracy, even though Xi didn't create the modern Chinese system.

You're making a common mistake of collapsing any Chinese-based entity with China as a nation.

Xiaomi is a private company, not an arm of the Chinese government. While it's true that the division between companies and the government in many cases can get a little blurred, I don't believe that Xiaomi gets to dip in to the Chinese central bank and take any of the $1.17T.

They had them at CES too.

(They had Joe McNally too, but he seemed to be real, and I didn't see him dance.)

As I wrote elsewhere:

Certainly does look like triple OIS, but a little bit more dissection would show for sure. OIS focus modules (VCMs) have eight electrical connections, instead of the usual two.

It might be they abandoned the triple OIS (having baked in a lot of additional cost, I might add) due to magnetic interference between the VCMs, that they still hoped to resolve until a point where it was too late to change them out to straight AF VCMs.

NOWHITELENS: Maybe mirrorless is the future. Only time will tell.
But one thing I know for sure :
These tiny things Sony calls full frame cameras are not the future unless future humans are midgets with very spindly fingers!

@biza43, one thought: digital cameras have more controls than film cameras. Film cameras didn't have functions associated with reviewing images, plus a whole host of other user functions.

@Suntan, immigrants commit crimes at a lower rate that US-born citizens. The likely reason being they fear getting deported.

SmilerGrogan: I don’t hang out with GoPro people so could someone explain: How is the lens on these cameras? And the compression? Is the footage nice and solid? Better or worse than an iPhone 7?

On article Lytro is officially shutting down (207 comments in total)
In reply to:

Jon Stern: From what I understand, most of their engineering staff were laid off a while ago. They built literally one copy of their cinema camera for rental, and then with no plans to scale from there, they showed the people who had made it happen the door.

Around the middle of last year, I saw quite a few resumes from ex-Lytro engineers come my way, and interviewed at least one person that I can recall.

No. I didn't hire them. You're going to laugh, but instead I hired someone from Juicero!

Although he was only there for 4 days before they shut down!

It's interesting that Raytrix GmbH, who have been around for years, without any of the Silicon Valley hype, continue to quietly exist. Selling plenoptic cameras for industrial use, to customers who have a problem that it solves.

FuhTeng: Good, a direct rival to the Yi action camera. Looks about perfect for me, but it seems to me it also shows off how incredibly overpriced the Hero 6 is. Sheesh.

The HERO 6 is now $399. $100 less than at launch.

sapple: Whenever I am on a plane that has GoPro channel I watch all the cool action videos of people doing cool stuff and think "I should get an action camera" then I remember that I don't go skiing in the Alps or mountain biking the Rockies, and the closest I would have to an action video is a slow hike through a local park.... Thinking of trying to edit a 3 hour hike into anything interesting makes me reconsider the whole thing.

Download GoPro Quik for mobile.

winkalman: If only there were any current phone options with a single, bigger sensor rather than 3 small terrible ones.

"It looks like the DPR armchair engineers are out in full force again."

@winkalman, I laughed when a read this. Thank you for helping start my day with a smile.

One thing about internet forums is you generally have no idea who you're talking to. I've been working in imaging for over 20 years. Six of those years were spent working on mobile phone cameras. Currently, I lead a group of 8 optical and opto-mechanical engineers at a major camera company. I'm not saying that I'm always right, but I'm no armchair engineer.

The Pureview 1020's 14.5mm is not competitive in 2018, when the vast majority of consumers opt for thin phones (half that thickness) that fit comfortably in jeans pockets. Phone companies have obsessively pushed to thinner form-factors - it's a significant marketing point.

Bigger sensors mean higher TTL (taller) lenses. Few people want a phone that isn't slim enough to fit in their pocket comfortably.
