これは「仏教の行と大脳生理」のポストに付いたコメントのやり取りで言い得て妙だと＝再録に至った次第

[…] このブログでは禅仏教を専ら神経生理の自動制御に帰結して論じていますが、そこでは「だから何ンなの」はめったに出て来ない。自動制御の稼動状態は誰の目にも明らかであるから解り易い。しかしその背後には不可解なものが多すぎる上に「ホンマ？」がついて回る。無心になる事で、経験則やDNAに予めプログラムされた自動制御に任せる。同様に生をカルマの生起に任せる。＝これで人智を超えたダルマによる完璧な対応処理が行なわれ全てメデタシメデタシなれば文句ナシ。－－－とはいかない。都合良い神ワザ伝説はいくらでも並ベられるし、それをもってスピリチュアルな調和が得られるなどと強弁しても意味はないーーーつまりそれが真実ではないのだから。＝真実ではない所がダルマゆえの真実か？と、解ったようなシタリ顔してもまた無意味であるし、だからサトリは犬のクソと言ってみても何も始らない。　つまり完璧な答はどこにも無い。 […]

スピさん、コメント深謝。御自身で諒解の如く言葉としての解答などどこにも無いでしょう。それでも何かスピリチュアルな真実をお持ちいただいたとか？　是非お聞きしたいものですね。
そもそも小生がやっているのはゼロから出発してのDⅠY禅探求です。つまり２５００年前同様、何の仏典も無い状態で、色々試しながらそれが「いわゆる」禅と伝えられているものと合致するか、その検証を試みている訳です。
自動制御は遇然の発見ながら、これこそが
釈尊が見出したもの、そのものであったとは完璧に納得。で、だから何ンなのよは、DIYそのものが答え。現にここに在り何だかンだやっている当人の在りよう、その事実、日常平常が答えです。ヤレ同心ニ重濃度針穴写真云々、ZAPPAの写真がどうのと、全て能書抜き、現にためらいも無くやった事、おそらくその解脱の上に在る自在が問題です。禅は能書でも足をひねる事でもなくいかにこだわり無く生きる事が出来るか、それが唯ーの目的。　(乞参照　＞ヨシ禅縁起）

〜〜〜で、ここまで来てハタと気がついた間抜け、[ Spiritualism ]と言うのはコメントを書いた誰かではなく実は大分前に書いた自分の古いポストからの抜粋であった。

で、そこでさらに出て来る疑問は、いったい誰がこの抜粋を作ってコメントに入れたのか？？？－－－そもそも１０００以上も有るポストの中から、しかも日文の内容を理解して撰択すると言う作業を、果たしてどっかのボランティアさんがやったのか、あるいは WP かグーグルの AⅠ が全自動で処理したのか？？？ ーーーそのどちらであったとしても、これは驚き以外の何物でも無いし, いささか怖い話でもある。ーーーつまり処理する目的で僕のブログを読んでいる目にとってこれらはどう見えているのか。ジャンクのベス単と禅がいかなる脈絡で捕えられていいるのか？？？　フシギ。

Leitz 50 mm-vs-Zeiss 55 mm

Casually I called Leitz Elmarit lens I used on the Nikon Z in the previous post, a homemade though, glass itself was a serious Leitz product. Hence, having a proper optical quality as we expect. —– ? was it ? = was that quality, within a normal standard ?

—– So, I made a comparizon.

This is the test image taken by the Leitz Elmarit P 50 mm F2.8 at F2.8. With the focus peaking. (Photo right was a part enlargement of the centre = the top of the tree) —– the small twig still maintain its detail though, is this fuzziness normal ?

So, to have a close comparizon, Zeiss Sonner FE 55 mm F1.8 lens was mounted to the same Nikon Z7 body and had the test shot on the same tree, same condition. (since Zeiss / Sony lens has a funny habit = keep move the focus, so that, click the shutter when focus was peaked) In the photo right, some leaves on the tree were coloured red = may be an effect of the chromatic aberration. Was it ? Wait a moment = this is not a £1 junk projection lens but a genuine Zeiss / Sony lens costed hundreds of the pounds. (Even though it was made in Thailand)

Then, I gave yet another test = Zeiss Sonner lens was mounted on the Sony A7R body and had exposure of F1.8 and F8. (manual focus) —– F1.8 image (photo above middle) was the sharpest among all the photos in this post. (Though, strangely F8 image = photo right, was soft —– very difficult to make a precise manual focus on this A7R camera)

Since the same Zeiss lens showed no chromatic aberration on the A7R body here, there is a possibility of either (1) Sony has correction program built into their image processor to compensate lens’s own aberration. or (2) The lens’s obstruction = keep moves its focus when the lens was not mounted on the Sony body = moves only a small part of lens, only to destruct the clear image, hence making big chromatic aberration on the Nikon Z body.

Yet those photos here showed very different strory. The photos were taken same as those photos above.

= Zeiss lens on the Sony A7R body. Exposed on F1.8 and F8. —– But here, F1.8 image (photo middle) showed funny chromatic aberration (red leaves)

(This is the puzzle = how those red leaves were created ? The Sony camera and their image processor seemed to hide too many puzzles.)

—– the correction program of Sony Image Processor may be working erratic. (still, how to make only some leaves red on the Nikon Z and on the Sony A7R as well looks too strange = In fact, the culprit mast be the Lens, not the camera, though, how this Zeiss FE lens can put the red color to a selected part of the image ? === this phenomenon needs to be investigated further !

This is a problem of the “Soft controled digital imaging” = it would make a pretty picture though, it may work, may not work like a Beauty App. That why I hate those artificial images. (Still, film photography can create strange phenomena too —– but, as I didn’t have an experience to enlarge a 35 mm color photo to 1.5 m big and examin the details, may be I was not aware )

Here, they are the shot to finish-off this argument (of Red Leaves) made by Zeiss Sonner 55 mm ZE lens. = The lens was tested at F1.8 if it showes chromatic aberration of red and green fringe on the roof pattern. = The result was as you see. (When the lens was fore-focused, the image has green fringe — photo above right)

And I found a very interesting bokeh pattern on the tree behind. The question is, is this the quarity of the lens which says “Sony / Zeiss Sonner” ? ? ? ( 55 mm is not special, neither F1.8 is difficult to design)

So, how about the chromatic aberration of the Nikon 50 mm F1.2 (photo middle) and F2.8 (photo right) —– a lots of red leaves seems to be here too ! = We shouldn’t be surprised. —– Otherwise we need to pay thousands of £ for a lens which shows no aberration on fully opened iris. === Only the question IS, why we need such perfect image ? ? ? (May be the obsession.) = If you want to see the perfect image, come down to the tree and see it close)

The reason why we don’t see such Chromatic aberration everyday, —– (1) We don’t use maximum F-aperture often, except in the very dark situation. And if it was dark, we can’t see such color fringe in the dark details. (2) In those lenses (Zeiss 55 mm, Nikkor 50 mm) when we stop down two or three stops, the aberration would be disappeared = hence we don’t became aware its existence. (3) We don’t enlarge the image to such big size. = so that, in the small print, the color fringe (even if it’s there) would be buried in the details. (If you are seeing the enlarged tree top photos in this post on a PC screen, it is the equivalent of seeing a 36×24 mm size photo enlarged to the 120 cm x 80 cm (43″x32″) and giving a close look.

The aberration is an optical phenomena, when the light was not converged into the focal point and spread to the surroundings as well, make the image fuzzy. Among the cause of such problem, if it was coused by the way how the light was bend differently by its color (= wave length) it was called Chromatic Aberration. As you might remember to see the rainbow 7 colors made by a prisome, when the light go through the glass they bend according to the wave length (= color). To solve this problem, converging lens which bend the red light more to outward and the diverging lens which bend the blue light more to outward were combined together to conpensate each other to the light concentrate to the same focal point (so to make a sharp picture). —– While making the light bend inward and outward, still make them to converge to the same focal point, optical designer use the fancy technique and special glass etc etc = that’s why good lens is using 10 or more glasses inside of one lens. (= making such lens hugely expensive) —– Sigh 😀

—– Still, it is rather rare to see such prominent Chromatic Aberration like the red leaves here, —– in most of the case, the fringe color appeared only on the edge of the details and make the picture just a bit soft. (Hence the most of the people doesn’t became aware such things ever existed in his lens. )

And in this point, why the Leitz projection lens I’ve talked on the begining of this post showed such character become clear, = the projection lens showes the 35 mm slide image hugely enlarged therefore the chromatic aberration would become quite visible yet, a bit soft image wouldn’t be much of the trouble as the larger the projected image, people view it from the larger distance.

It seems, the battle between the camera, lens keep going on. 😀

The Moon of 15th August

As I said, in the old Moon calender 15th August is always full moon. So, to have a full moon tonight was just a coincidence and I found her behind a tree at rather late 22:00.

—– I took the pictures of the full moon many times, using Tamron SP 500 mm lens. But I didn’t want to do the same on this time, so took a picture of her with a kind of ordinary lens = Leiz Elmarit P 50 mm F 2.8 projection lens (costed me £1) modified to use on the Nikon Z camera, because, it was not a very sexy image with fuzzy lens. —– And after I open a photo on a PC screen, I noticed that there was a reflection of my room on the window glass = Oh, no, I should have put light off. How careless I was. The moon of 15th August has gone and we never have another chance for re-take. (Next full moon is not the 15th August one) We have only one life.

.

15th of August

In the old moon calender 15th August has always full moon. And this is the day when the last World War was ended. So, there was a memorial ceremony for the 3 million war dead attended by the Japanese Emperor and the Empress. (Photo above right)

And it is often the time when Japan has a visiting typhoon. (Photo left)

Seemingly Japan was no exception, thanks to the climate change and having an extreme hot summer as well, making a record 40.7 degree C at northern Japan, Yamagata.

Poor fellow Japanese. —— Thenks goodness, I’m away.

Hibiscus

When you hear the name Hibiscus, you may imagine a red flower in a travel brochure of tropical island. Yet still, a kind of flowers belong to Hibiscus group = in the Malvaceae family is amazingly common and flowering everywhere.

This is a Hollyhocks. (seems to be Althaea rosea)

—– incidentally, this plant is a sister of Marshmallow (Yes, that soft white sweets) = the sweets used to be made using a sap from the roots of the Marshmallow.

And this one seems Hibiscus synacus.

But this one seems to be a very different garden valiety though, still pretty like a Hibiscus.

And you may remember this small flower in a grass patch, like a weed desperately clinging to the ground. Still, this one belongs to the Hibiscus family.

It’s somewhat interesting to think about that what sort of the fate or history pushed this plant to cling and survived on a rather poor dry ground ? —– Was that only a niche she found ? (We all knows, life is hard — she must be a rather lucky one, as she has achieved to make a flower at least !) —– by the way, did you know that the Hibiscus plant is Cannivorous = in the night, their stigma catch and strangulates a small insct and suck their body fluid out. = That’s what I heard, but not know the truth.

NZ – B – lens

I wrote about NZ lens more than a year ago. Since then I haven’t go out with that lens often. Big bright lens is too big to carry in my pocket.

So, only the front element was recycled then. But, how about many other lenses ? In that 18~200 mm Nikon Zoom lens, there were 3 more groups of glasses were used. = When I tested, I found that the third group was fit to the purpose straight. = easy to make-up as a usable optics — I mean, for my purpose. (Left top is USM / Silentwave motor and the D was the diverging lens I used for an experiment “Retrofocus” as the front element.)

So, the third group glass together with its sliding barrel was just glued to the Nikon-Z mount ring. In this structure, the movement of the glass makes a focus from infinity to x0.6.

As you might have guest, this lens wouldn’t give any clear sharp image. = still, may suit for some subject. Wait and see. 😀 ( I’m serious)

.

Sony lens myth (3)

Some time ago, I wrote about the strange behaviour of the Sony 30 mm F3.5 Macro lens when it was mounted on the other camera. (Sony lens moves their focus while the lens was not mounted on their Sony camera, = even without having connected to the power.

mm

In fact, I’ve written about the Chinese made NEX-NZ lens mount adaptor, in a postscript in the Homemade NEX-NZ adaptor post.

While testing this Chinese adaptor with Sony / Zeiss 55 mm 1.8 lens on Nikon Z7 camera, I noticed that this lens behaves same as to 30 mm F3.5 lens.

Those 6 photos above are the continuous shot showing how this 55 mm lens moves its focus when the camera was aimed to the outside. The lens moves its focus from Close to infinity then to very close again, obstructing anybody’s attempt to use the lens anywhere else of the Sony camera.

—– It is quite natural that the camera Co, hate other made lens used on their camera, but why they need to block their lens used / tested on the another camera ? — Is that because the lens needed to be used with their own correction program such as Chromatic, Distortion correction built into their image procesor ?

As I wrote it before, the most interesting question is, what kind of device or mechanism made such function works. —– the focus motor might be a silent stepper motor kind (but it makes some noise) though, what sort of the power back-up system maks its function keep working, —– how it retains the power without having the trouble of re-charge ? ? ? ? — small battery or super capacitor kind ? (Sony didn’t give any answer for those inquiry. — and I haven’t disassembled and checked inside of the lens yet.)

My Dictionary

This is my English dictionary which I’ve been using for the past 60 years. My brother gave it to me when I passed the hi-school enrollment. —– Since then this one served for me to know the meaning of the word, and check spelling etc.

(I’m changing the cover after 18 years of use.)

(It seemed people surprised to find that me not having Oxford = What’s wrong ?) —– They surprised me not to take drug, no alchol, no TV, no smartphone, no smoke, no woman, even not gay, yet still eat meat = and disassemble expensive camera = what’s wrong. (it’s not your business ) =

If I follow the way of the other people, I didn’t need to come to the Zen !

Inside, a small note was left that I got it 1960 when I was 15 years old. (15 years old boy started to use it 60 years ago and after 60 years still using it exactry the same way. = this was the reason why people don’t argue with Zennist.) 😀

I don’t think I’m proud to use one dictionary for all through life. In fact, there was a time that I was using SONY electronic dictionary which was very useful and convenient though, as it was based on the mini-disc memory system, mechanical instability hindered its use. = when it works it was brilliant but the trouble was, it didn’t work when I needed the most. —– and on the end of its life, it left the last epitaph “Please insert the disc correctly”. = Maybe I should have tried to get another Electronic Dictionary but it didn’t happen (no Akihabara in London, and I was not using Amazon then. = So, that was what it should have been and has bee as it was. —– In compalison, people struggling to get new one unnecessarily)

(I guess, maybe other people are using app dictionary kind on smartphone but that was what I hate most = I hate Google spy on my mail, eBay trace my type, taste etc etc Why they don’t leave me alone ? —– For them, I’m only a subject to squeeze out a profit and for me, they are only a necessary evil)

And awhile ago, I got a Thesaurus from Lidl for a whopping £1.5, my writing got a great sophistication and the eloquence. ( Ha ha ha 😀 )

German Realism

There was an almost ending exhibition tytled “Magic Realism” at the Tate Modern.

But I’m not guiding you or work as a catalog —– you better find them.

It seemed, there was only one Paul Klee = counter part of Joan Milo ?

(Only this photo was taken by 110 Pentax 24 mm lens)

(And like all other photos, this one was taken by a home made so-called ZM-2 lens)

Human history has two drastic experiments, one was the Chinese Cultural Revolution, which destroyed all the culture and killed a population of 40 million for the sake of Chiarman Mao’s greed for power. And the other was the Weimar German Republic till the birth of Nazis when all the “Idea” was developed and tested in Art as well.

All the human issue, wemen’s issue was also discussed and argued.

I don’t know why when those hidden desire was unleashed, why they become to grotesque Hentai Images. Was that the face of hidden reality ?

But the most cynical irony was, even the most well designed democratic system couldn’t save the burden and the poverty from the war reparations, and push the country to even more disastrous rise of the Nazis. After all, all those distorted faces showed their pain. They were not a happy people. This true reflection was what the Realism mean.
