Deteriorating NIKON




This Nikon Z7 is only about one year in my hand. Camera is functioning normal (like other camera such as D850, A7R4 etc) though, this camera started to show its own deterioration. = such as covers of the connecting points expanded and no longer works as a seal cap (Photo above left). Its skin started to fragmenting (Photo middle) and the cover for the memory card chamber started to expand the size (Photo right) = may not work for dust or water seal any more.

I reported this to Nikon asking their help more than 10 days ago through their web site though, no response at all. = it seems the most serious deterioration Nikon is having is their system / communication / customer care.

I don’t know whether their move of the office from the Richmond to Surbiton was for a cost cutting or else, cutting the meagre cost of plastic material couldn’t make much savings, I think. The one thing clear was, like any other camera manufacturer, Nikon’s financial position is very bad too = may be as such bad try to save a penny from the price of plastic.

By the way, don’t forget, I’m not talking about their cheap toy camera, but it is the 3,000 pound made in Japan camera. = I should be treated with a suply of bit higher quality plastic.

The decent quality plastic should last many many years — the plastic cover on D850 or EOS still keep its shape perfect (after 3 years, 5years) —– is the Nikon quality became a myth now ?

How to deal with Cold,Flu,C-19 Granny’s way

They are the advises made by Dr.Med Seiji Ishigro (by a Ytube Viz) which was told by granny.

  • When you caught cold (or Flu, C-19) stay in a bed and keep you warm. (= Body’s immune system needs higher body temperature to work. = When you were cold You get Cold)
  • Stay in a bed mean, you have to be laying down to have better condition of blood circulation and the ease of your guts. Because of the body’s immune system / antibody was produced in the intestine.
  • Body temperature was rose by the body, not a toxin of the virus = because it needs higher temperature for the antibody to work. Body themselves knows this, hence rose their own temperature. = It’s mean don’t use the medicine to lower the temperature.
  • Eat well such as Kiwi, Lemon for the vitamin C. Good Cholesterol (meat, egg, cheese etc) and the mushroom for the vitamin D.
  • Don’t panic = You may get well soon when you stay in a bed for few days and get sweat for one night = It’s a cold. Million of years we’ve been with them, still we are here surviving.
  • (Though, if it didn’t work, don’t come back here to brame Dr Ishigro, he was told by the local granny, it’s a cetury old granny’s way)

Daisetsu Suzuki — ZEN

Fortunet to some of you (unfortunet to others) This Viz was in Japanese.

But, he was not a Zen monk — he was a trancelator and he was talking about the difference of the concept between the east and the west. —– So, he speaks, the notion of FREE in the west IS a notion of a relationship = has to start from two subjects. And its meaning IS = the one is free from the other. It is the relation of Subject and the Object. Dominant and Subjected. Such as the God and I. = So, the fundamental ethos / idea of the west starts from here, therefore the social structure too.

In contrast, there is no such God in the east. Instead, the heaven and the nature which we are in its part. Therefore, in the east, we were not created by the God, but we are exists as a part of the universe, nature from the start.

A word which was normally assigned to the word “Free” was 自由(Jiyu) though, the real meaning of this word in the east IS “To be as it is”. —– If it was the case of you = You to be as real you ARE (not the one who you imagined or others defined). (this is close to the meaning of the Zen notion 自在(Jizai)). So, in the Buddhism, You are not exists but the Nature (Dharma which you were a part) IS. So that, the Rinzai Zen try to make you aware who (real) you ARE through dialogue. And the Soto Zen try to disolve you as a part of the nature through practice (sitting and the other daily activities).

So, he was talking something like that.

Sony vs Nikon

AI Nikkor 50mm F1.2 on Nikon Z7 / Zeiss Sonner FE 55 mm F1.8 / Pentax 110 Auto 24 mm on Sony A7R4

This is rather repeated subject = compalison of Nikon 50 mm and Zeiss 55 mm lens and the Image Sensor of each 46MP and 62MP.

Z55 F1.8 – A7R4 (100cm away)
AI N 50 F1.2 – A7R4 (F1.2) (lens was mounted through NIK – NEX adapter)
P110 24mm – A7R4 (Center of image was quite good)
AI 50 F1.2 – N Z7 (The same Nikon lens on Nikon Z7 body)
AI 50 F1.2 –F1.2 & F2.0 on N Z7 (when the iris was close to F2 its image get very clear)
P110 24 – N Z7

On this test Nikon Z7 46MP image sensor performed almost as good as Sony. The Pentax 110 Auto 24 mm lens performed very well on both Nikon and Sony body. (hence this tiny lens is the most well used lens on my gajet)

.

Macro shots (2)


On this post, all the shots were made by Pentax 110 Auto 24 mm lens on Sony A7R4. And looks like macro shots were the heavily cloped small part of the original photo’s part enlargement —– can you find where it’s came from ?

So, it is clear, a lens I bought for £5 from a junk box, Pentax 110 Auto 24 mm lens has the quality of the (almost) top lens, and the 60MP image sensor of Sony A7R4 can capture (almost) whole amount of those visual information there. Therefore, a wide angle casual shot of a 24 mm lens was in fact, holding the details of the macro level too.

Pretty Good isn’t it ! So, Ilike this Pentax 110 Auto lens on the Sony A7R4 camera always in my pocket. 😀

Macro shot ?

Z55 – A7R4

Once before I found a trouble of manual focusing in the Sony camera. So, I was testing Zeiss 55mm lens on A7R4 body with Focus peaking and the Focus magnifire. —— This time both function worked well = AND I amazed by its fine details of the captured image. = The silk flower was 100 cm away yet the enlarged image showed a real close-up = macro quality.

Z55 – A7R4

I wonder IF this fine quality came from the quality of the Zeiss Sonner FE 1.8/55 ZA lens or the camera’s 60MP image sensor ?

AI Nikkor 50 – A7R4

For comparison, this one was AI Nikkor 50 mm F1.2 (at F1.2 / 100 cm) on A7R4 (this 50 years old 50 mm lens seems to be a bit softer than Zeiss 55 mm —– But, F1.8 lens got to be sharper than F1.2 !)

AI N 50 – N Z7

Then, how about the AI Nikkor 50 mm F1.2 lens on Nikon Z7 ? It’s haed to tell if a bit softer image was caused by a larger F aperture (F1.2 instead of F1.8) or a bit fewer pixel number (46MP instead of 62MP).

P110-24 – A7R4

On the same setting, I tested it with the remotest possible lens = Pentax 110 Auto 24mm F2.8 lens === 24 mm lens image was far smaller than the 55 mm lens. Still, the enlarged image showed quite a fine detail !

It’s suggests that as long as the lens was seriously designed good lens, its can produces very fine details = IF the resulting image was not very fine, it was because, the camera / image sensor / image processer was not good enough.

P110 – NZ7

This is the comparison = The same Pentax 110 lens was mounted on the Nikon Z7 body through a homemade NEX – NZ adapter. —– Even though the same optical image was projected, the smaller sensor seemed to produces a bit rougher image.

Godo – A7R4

So, see the image of the lens which was not seriousely designed or made = homemade Godo-lens.

NZ-B – N-Z7

Then, how about the image made by yet another fine camera Nikon Z7. —– But (you believe it or not) I don’t have an authentic lens for this Z7. (I’ve been empoverished by its XQD memory (made by Sony), expensive spare battery etc —– I can not afford to buy their lens.)

So, the Z7 camera was tested with another homemade lens, NZ-B lens which showed very fine undefined image !

Daikon 2020

So, I’m watching the same windowscape of my kitchen window.

Only a difference in these days was, the leaves of the Daikon head. Which was growing well. Some of you might say that I can cut them small and eat or put in a Miso soup —– I know. But I want them to live free and grow. (I’ve tormented the Daikon root badly enough, boil her alive and eat = I need to make a hypocritical excuse by humainly saving the leaves)

It’s a spring. (Forget the hell outside or the world beyond)

So, the Daikon is having her flower bud —– though, would the flower open or not is the different story.

https://yoshizen.wordpress.com/2017/05/17/daikon-flowers/

When she got 30cm tall, before opening the flowers, she lost a vigor of the life. I couldn’t see any reason why, —– it was same as last time. How shame. (May be I need to learn about the Daikon plant start from its seed, not the left over top of a Daikon food.)

MP Cherry 2020

Those photos of the Multi-petal Cherry was taken by a homemade lens, NZ-B lens on Nikon Z7


May be in a normal sense, such lens may not serve for a photographical use. Yet still, any image could be an image as long as the author = I wanted. Why not ?

Under the COVID-19 pandemic, our activities and the movement has been restricted, so the picture I am producing may looks one pattern too. (Sorry)

The lens NZ-B seemed to have two glasses of which I re-mounted into a zooming barrel and able to focus from infinity to 1/3 close-up. Still, born to be a simple junk lens the image never be sharp. —— But that was what I wanted. 😀

Requiem

Those screen shots of the Youtube viz was made with Canon 5D-MkIII, EF 40mm F 2.8 set manually to F5.6, 1/8 ~ 1/30 Sec’ = ISO was selected to enable this exposure.

Under the restriction we stay at home —– to spend more time with internet. = So, I encountered one of the most distinguishable, Morzart’s Requiem which was packed with the strongest anger ( = no sobbing, or asking mercy but an explosion of the anger — may be toward the God) But, mind you this recording was made 2014 —– I think the Venezuela was not in the hell (yet). And this is not my sarcasm toward the COVID-19 trouble we are having. (Timing was purely the coincidence) — but, my coincidence was always having had the message = the God may be angry.)

The musisians of this orchestra and the choir must be the ethnically the most diversified members — that’s what I noticed.

In my view, the Requiem is only a music Mozart created for himself with his true sentiment. (Others were just a commercial products to buy a favour of the society)

(Morzart said to be a member of the Free Masons though, when he died even before completion of this Requiem, nobody helped his funeral and he was buried to a common grave. — was this what he deserve ?)

How NOT to get COVID-19

This was a tweet which has been Re-tweeted 100.000 times in two days,

[the advise, how NOT to get COVID-19 infected] made by a (Prof) Takayuki Miyazawa(宮沢孝幸准教授) of the Virus study, Kyoto Uni’, Japan

(1) Think, you were a person already infected by the COVID-19.

(2) And Think, try NOT to infect others.

(3) Breath through the Nose. (not by the mouth)

(4) Don’t touch your Nose, Eyes, Mouth while you are out.

(5) While you are eating, just eat, NOT to SPEAK (or Talk)

(of course, those MIND-SET were on top of the ordinary precaution = What to DO, such as [Wash your hand] [Keep a distance to each other] etc ——- may be because of those mind set and the attitude, the number of the infected in Japan is (on 30-03-2020) only 2.700 cases so far.

Stay safe and keep you well.
