Rouseabout: My experience with Nikon Fw updates is that they primarily render OEM products such as batteries unusable.

you want to say non-OEM?
Because OEM is outsourced but still authentic product.

stevo23: What did Samsung first say when rumors surfaced? I recall there was denial.

Strange that Pentax would exit after just releasing such a killer set of DSLRs.

To be exact:
The rumor was Samsung pull off camera business,
on Dec 2. 2015
The last camera announcement from Samsung:
NX500, Feb 5, 2015,
it is 10 month apart

The rumor now is Ricoh considering pull of consumer camera market:
Last consumer pentax/ricoh camera:
THETA : Sep 3, 2015
K-70: Jun 8, 2016
10 Months too

ogl: As I remember - Samsung denied too, even officially, but it was the truth. The silence withdraw from the market.

Pay attention - Ricoh doesn't refute the information of Nikkei, they give very evasive answer - "This article is not based on RICOH's official announcement".
No any word - wrong or inaccurate information, but placatory words which means almost nothing.
I don't think that Nikkei wrote the article based on fabrication. I think they have insider information.

From post below , by Ricoh:
From Ricoh:

"Impairment losses in traditional camera business"

"Clarify criteria for shutting down, maintaining, and investing in businesses and services"

Page 12

https://www.ricoh.com/IR/data/pre/pdf/ir_pre2017.pdf

See, Nikkei could be using the ricoh report as one of its sources, and their "consumer camera business" is part of money-losing "traditional camera business" which Nikkei referred.

@Alex Sarbu

Focusing resource on high value-add product
keep on expanding VR market
expanding in the solution business field for corporate

Neither of above saying stay on consumer camera business, and by reiterating above fields, it silently confirming that consumer business is shrinking.

When read between lines, that Ricoh doesn't "deny" the Nikkei report.
"Today there was an article saying that RICOH considers to shrink the camera business and withdraw from consumer products. This article is not based on RICOH's official announcement."

Yes, we know Nikkei report is not based on RICOH's official announcement. However, is it based on solid internal source or some off-record talking with reporter? RICOH didn't deny this.

And RICOH doesn't deny considering shrinking consumer business ( if you see THETA and VR as new branch, not covered by traditional consumer camera business), even withdrawing from it.

why no questions regards "general strategy for APS-C e-mount lenses"?

rrccad: Not too outlandish when canon is already stating they are coming out with a 120mp camera.

2015 was 250MP sensor.
Back. 2010, Canon show cased 120MP sensor, which never see the light.

princecody: Has Sony perfected the Art of the sensor? Is that why 80% of the camera brands use Sony sensors?

The problem is, the other 20% of camera brands hold a little more than 50% shares of camera market, at least true for ILC market.

Glen Barrington: Has Samsung ever said WHY they are doing this? I guess I don't really care so long as *I* don't get shorted in terms of the quality of experience, but I seems like an odd thing to do.

Since Samsung had tout ISOCELL in marketing of the phone, so the Sony sensor have to have similar tech, otherwise customers can sue it for false advertising.

Also other manufacturers have similar tech for different marketing names, like deep trench for omnivision

rfsIII: Am I misreading this caption: "This image was shot at the same nominal resolution but with red, green and blue information captured for each output pixel"
To me it sounds like the author shot the RG&B separately on a monochrome sensor (perhaps using colored filters as in olden days?)
And also, why the secrecy about which camera makers rotate their sensors 45 degrees?

for current 45 degree aligned sensors, I think sony F65-F55-F5 using Q67 type of 45 degree sensor.

Sony also have an array of current video cams using smaller format sensor called clearvid, those are 45 degree too

Seeky: Well, I don't know, but the Twitter feed of Akyoshi Kitaoka is full of tweets stating that there are indeed red (or reddish) pixels in the image he shows. I'm a bit puzzled by the statement in this article: "red is not the highest value for any individual pixel in the image. Hence, no 'red pixel' in the image."
But this still means there are pixels in this RGB image with a value for "R" right?

You can't say mid-gray 127:127:127 as "red" pixel, although it does have red channel that has equal brightness as the other two channels.

So, he is correct on there is no "red pixel".

On article Sony FE 100mm F2.8 STF bokeh demystified (355 comments in total)
In reply to:

liquidsquid: Wow, if they gave the user the ability to swap that filter out with other styles, that would allow for some really creative tools.

Actually, you can mimic this effect (at lesser degree) on any lenses, by putting UV filter on lenses, and use markers to draw shades on outer ring of UV filter.

Of course it won't replace STF lens, but it is certainly more versatile.

StephanBG: This press release is not about the DL line and development costs.

The pr is about Nikon having massive losses in 3 consecutive quarters.

Nikon has axed 1000 employees in 2016 bt that didn't make the outlook for 2017 any better.

The DL line has been cut to keep the Nikon boat afloat, yes it's that urgent.

You didn't read the most recent news.
Nikon just posted another 30 billion yen lost, for 3 quarters end 12/31/2016, and total 53 billion yen lost due to reconstruction.
Counting -30b only compared with 45b operation income for past 3qts, this makes last 3qts barely profitable if not a overall lost.

And it is certain that this FY would be a huge lost

I think the result is recreated based on imagination, not based on original picture, thus it can't be admit as evidences in court hearing. No matter how CSI presents them.

Bruno E: Maybe overlooking the obvious, but if they claim readout speed is 1/120 of a second, how do you get to 1000fps?

We don't need to wait all data are read in one frame to begin reading next frame.
In an extreme case, let's say sensor spend 1/1000s to read one row of frame,
time line:
1/1000s : reading 1st row on frame-1
2/1000s : reading 2nd row on frame-1, 1st row on frame-2
3/1000s : reading 3rd row on frame-1, 2nd row on frame-2, 3rd row on frame-3
...
1s: reading 1000th row on frame-1, 999th row on frame-2, ... 1st row on frame-1000

In this case, the read out speed is 1 second, however, you still got 1000 fps (with horrible jello effect) on full HD (almost 1080p)

belle100: Am I mistaken. Is this the same technology as the stack sensor in RX100-V with DRAM layer??

Sony didn't elaborate how DRAM chips on RX100V integrated. So
1. It could be same design as here
2. It could be DRAM integrated in same layer as circuit, so only two layers in RX100V
3. It could be DRAM is third layer, data has to pass circuit, then to DRAM. For tech here, it seems data are directly moved to DRAM before any other circuits (may be with exception of ADC)
