Hm... if you like a girl that is the language you would use:



I am not even mentioning that only a complete fail would choose a constantly moving waterfall to test a feature which is declared as working best with stationary objects.
And "surprisingly" then someone turns to 100% static test charts and photos of concrete city buildings, when covering the same question for the brand he is a fan of.

Amazon/dpr is an advertisement job, similar to Dxo and others. Don't mistake it for anything close to journalism or neutral/professional.

I once wrote a personal product review there and a North Korean "moderator" censored/deleted it quickly since my view "did not fit to their experiences". It's a little propaganda outfit.

If you want software automation on a fully manual lens: yes, sure (just the aperture setting, nothing else).

In practise the tasks depends on your shooting style. The manual lenses I used were wide angle for landscape and there after a short while I found my preferred aperture setting. So no "writing down" required, I knew the lens was set at F5.6 (or whatever) all the time.

I have created dozens of lcps and they can hold varying data for different (zoom) focal lengths and apertures. A good profile has data for all apertures separately, so there is no need to interpolate. The recommended minimum is three.

The way I handled all this with manual lenses is to fill the aperture metadata field using exiftoolGUI. Lr will then pick this up and apply the right correction. Obviously another step to do but worth it.

It is not abuse, it is my full legal right. These laws are made explicitly to support B&M stores, btw. They simply level the playing field between B&M stores and online stores as online stores also have to handle opened boxes now. Else everyone would "try" in a local store and buy online.
The law states explicitly that it is my right to "check" the product at home and that this is the intention of the 14 day return right (no need to give reasons).

And if some idiot retailer believes he doesn't want to do business with me because he is too incompetent to live within the legal and market environment, they are as free as I am to pick another one.



I do. At home, in good light, 14 days. Not 5 minutes in a store.



The investment on my side to "build a relationship" is not justified by benefits. If I see the dealer makes an above average tangible investment in me first, then I might consider this, but not before.

Nikon selling -16,1% DSLRs, -15,5% lenses, -18,5% compacts this FY18/3
Posted By beholder3

Canon's most recent figures from a couple of weeks ago said about units sold:
  • Canon -3% DSLRs and mirrorless (versus the -16,1% Nikon).

  • Canon -1% compacts (versus the -18,5% Nikon)



Canon in Imaging systems expects sales of 1,133 billions of yen with 172 billions of yen operating profit.
Nikon in Imaging Products Business expects sales of 355 billions of yen with 25 billions of yen operating profit.
Sony in Imaging products and Solutions expects sales of 650 billions of yen with 72 billions of yen operating profit. This does include their (here: Olympus & Sony) medical business though, for which we know little other than they target 200 billion sales for 2021.

Sony expects to sell 4.2 million cameras in total: compacts + ILC (no data given on share).
Nikon expects to sell 6.5 million cameras in total: compacts (2.6) + ILC (3.9).
Canon expects to sell 10 million cameras in total: 4,3 million compacts + 5,7 million ILC.

Nikon is a niche player compared to Canon now and shrinking much faster even. Quite possible Sony and/or Fuji to pass them by or already have done so.

This sounds good in theory but still is going to exclude all enthusiasts, who want a "proper camera" with IL and physical dials, but cant afford $2000+ entertainment electronic devices.

The margins on the top tier products are so "good" for sellers because they are hugely overpriced for what you get. I do sometimes feel like a sheep or Apple nerd, when I willingly spend these amounts on photo stuff.

DSLR: from 3.1 million sold in FY17/3 down to 2.6 million forecast for FY18/3 = -16,1%
Lenses: from 4.62 million sold in FY17/3 down to 3.9 million forecast for FY18/3 = -15,5%
Compacts: from 3.19 million sold in FY17/3 down to 2.6 million forecast for FY18/3 = -18,5%

So all markets are shrinking in sync, compact are not dropping off much quicker than ILC.

Bad for customers is the drift to more expensive / high price/margin items. But that is good for the company, so with much less customers the monetary sales figures are only shrinking -7% this year and operating profit is up.

They are firing 3,350 employees in Imaging business and 1,000 employees in lithography for a total of 4,350 employees.
In 2015 they had about 25,400 employees total, so this year they are firing more than 1/6th of all they staff.

Generally there is a move in the industry to disengage customers with less funds to spend and focus on the wealthy ones only.

It still makes sense to assume people will be watching images as a whole as if they were looking through the 43mm limited lens. Then a human can resolve about 6 MPx.

If you have techno geeks zooming into images on screen on inspecting prints with their nose to the canvas, obviously the requirements could go to infinity. Magnification is proportional to DoF/noise/dynamic range perception.

It is a very subjective personal choice if you care for those types of people's opinion or no.

It all is between the ears of the people.

Nikon giving up in Brazil, retrenching in Indonesia

QuoteQuote:

Nikon is expected to continue to provide repair services for existing customers, but it has decided to close its online sales site, effectively ending its direct sales activity in Brazil for digital cameras.
Nikon is also changing tack in Indonesia. When the company set up a sales company there in 2013, the main focus was on digital cameras. But it ended direct sales of cameras this past spring and now just provides support for sales agents. The emphasis is now on is industrial equipment like x-ray inspection systems and contactless 3D measurement systems to meet growing demand in the auto sector.

In Germany I get to handle the actual unit I am going to buy online for free for 14 days at home outside and with all my lenses or cameras for free. If I try to do that in a B&M store they give me 5 minutes max in their dark store with a crappy test cam of their choice.
That is exactly why I buy photo stuff online: Much, much better try-before-you-buy option.

The transit risk is purely on the dealer here.

Not.

As any OEM lens it just "needs" to achieve about 90% of the performance of the best lens on the market to be able to be priced at +50% more than 3rd party products (in this case = >1,500 EUR) and still be a good success.

That always was the case and always will be.

Where is the value add of a local shop for buyers?

Prices are higher.
Options to try out equipment for free are much worse than online.
They do not provide any meaningful service.
They have a large history of trying to trick you into using manufacturer warranties where actually they themselves are legally obliged to handle product defects.

I won't miss a single brick and mortar camera store.

I suggest reading this thread here including the links given:
resizing algorithms - XnView Software
The whole topic is way more complex than most people think.

Lanczos seems the best option. XnView offers:
  • Lanczos (3)

  • next neighbor

  • bilinear

  • hermite

  • Gaussian

  • Bell

  • Bspline

  • Mitchell

  • Hannig

  • Cubic

Feel free to find the best for your specific case.

Just from Lanczos there are five subversions.

Nikon firing nearly 10% of photo staff and shutting down DSLR lens / compact plant

I think I can add an answer even though I believe some whiners will still find excuses to whine:

That programmable macro feature is what I successfully tried with the K-1. It is already there.
Just take Image Transmitter 2 and any open source windows macro recorder (many are quite advanced in their scriptability).
IT2 gives you the option to make microfocus adjustments in one direction. You just need the script to BEGIN LOOP / TRIGGER CAMERA / ADJUST FOCUS +1 FORWARD / END LOOP. Repeat as often as you wish. And set it to move forward multiple times per loop if needed.

This macro shooting support came with the last update of IT2.

BTW, screw driven macro lenses have some tolerances in the coupling, so the focus often only starts to shift after a dozen software focus shifts.

Millions if not billions of people consume photos via their smartphones mostly or only.
Even what to probably refer to as "web size" is too high quality requirement then, assuming you mean something on a PC screen about 15-20cm width.
People today consume images at smaller size than polaroids were.

There is a huge two-class-market here with 1,000 buyers:
  • 998 people watch photos at max with 12cm width and dont want to spend a lot of money or time to learn or lug around complicated extra toys. They do not care about "oversaturation" or "sharpening artifacts" and probaly couldnt see them even if you told them. Change lenses? How old school is that? Not worth it. Cool looking software filters to slap on in app is important.

  • 2 people want to "print large" and worry about distortion and chromatic aberrations and are willing to spend a lot of money on an expesnive and high class camera such the K-S2.

The first group is growing. The second group is shrinking.

We are talking about the mass market of "a nice relaxed overland flight with the family/children". The word "advanced" all by itself would be a no-no for advertising. And the jet fighter plane is a complete fail there. It is by all accounts sub-par in its market appeal.
This is purely ignorance on the side of the manufacturer of the jet fighter plane, not on side of the market, if he ignores the market requirements.

Nobody in the biology market cared if the Dodo was "more advanced" than a cockroach.

So if you run out of excuses and arguments you attack the person stating an opinion? *facepalm*

You still owe us a source to your claim on lens types produced. Liars and fanboys don't need sources or arguments. The others do.

Think again. What you said would only be possible if they had half a factory elsewhere sitting idle until now. Which is 100% the same disaster and would tell the same story about lack of product appeal to the market.

However you look at it, Nikon seems to have a major lens sales problem.

I believe only top end lenses were made there. ;)

Interesting:
Nikon Closes Camera Factory in China, Blames Rise of Smartphones

Firing about 10% of your overall photo business staff is quite a move, if not unexpected. It's more than twice the amount of staff they already fired a couple of months ago.

While Nikon marketing would like to concentrate the media discussion on "the smartphones are guilty", that plant was producing Nikon DSLR lenses just as much. Obviously those are not selling ok as well.

It also is interesting that with better products than Nikon Canon was able to actually grow +13% (current quarter) their compact camera sales. So it is neither "the market" or "the smartphones" who damage sales figures any longer, it just is poor product development which is to blame. No G9X Mark II, no RX100 from Nikon.

You need to learn a couple of basics to understand.

If you want to compare then you need to export/develop both images to the same size/resolution (e.g. 8 MPx for viewing on a UHD monitor).
Then you shoot your test image at the exact same settings for time and aperture, but for the K-1 you go for a one (actually 1.5 divided by 1.4) stop higher ISO (e.g. 3200 vs 1600).
And: Obviously you have to use a FF lens, not that Sigma on the K-1.

Now you should see that at this higher ISO the K-1 image looks the same as the K-70.

For the "why" and "how" use the search here or google. It all has been explained a million times in detail.
