Dorkbot London 95

Dorkbot is a strange social gathering — they says the gathering of the people doing strange things in electronics.       Superficially it is the Geeks gathering yet in reality, some people are overlapping with computer hacker, anarchist, social activists etc etc. sometime a kind beyond the ordinary brain.  Its mean, for certain situation, they are quite resorceful and effective people.

Both a question and a proposition. Both are projects which would welcome wider collaboration and the ingenuity that Dorkbot may bring.

They are the regulars, friends. —– (Those photos were taken by the 100year oled Kodak Vest pocket camera lens on Nikon Z7 = sorry about the focus,  it was to scueez its pantograph )

I’ve been with them —– gosh, over 15 years ! ?

Joe Rush in the Southwark London

South of Themes river, around the London Bridge, and down towards Deptford, navel center Greenwich — used to be a ship building and the industrial area —– .   So, we can see a lot of disused buildings, abandoned empty spaces etc. even now.   And, somewhere, somewhere we saw “re-development” etc though, ? ? ?    (kind of sky-scraper, Shard is the prominent one)

An easiest “Re-development” is to put the chairs and tables in the empty space and sell the drink (and some food) = as long as somebody buy a drink, it makes a business.  A place called Vinegar Yard is such kind.   Put a disused Train coach on top was a option (and may be used as an office space, in the same time as an eye-catching display.)  

Huge ants infesting the building must be another option.  Then I realised that, this is a part of the Joe Rush Exhibition.

Joe Rush is a well-known figure among the festival fan as he is the fixture of the Glastonbury Festival while displaying huge  so-called wasteland art.  (Using discarded objects such as a parts of the machine etc and create a kind of the sculpture —– so, the aforesaid Ant was made out of motorbike’s fuel tank and the photo above seems to be out of piping connector, and photo right seems to be an Italian coffee maker)   I met him about 15 (?) years ago. And remember when I visited his work shop in the Deptford creek.

(Don’t ask me what are they.)   But, something fuzzy image, photo left was taken by Kodak Vest Pocket Camera Lens.

No idea what this one was ?

Not only the mechanical sculpture, south london got many big toy for the grown-ups.  (not Haley, but Triumph = THE British !)

And Southwark can offer enough drink.

Since the time of Shakspere.

In case if the drink excess, you can treat it with no problem.  (everything handy here)

And the posh food as well. (The mix of discarded junk and the too clean new fabrication is the Southwark London)

All the photos here (except one) were taken by the 110 Pentax 24mm lens on the Nikon Z7

First Reiwa (令和) Sky

So, this is the sunrise (over the roof) 1st of April 2019  06:18 ( = British Summer time 07:18) by Zeiss 18mm F3.5 on Nikon 850

And this is the same sky but a minuets before of the top photo, taken by 110 Pentax 24mm on Nikon Z7   (It seems Zeiss lens showed much clear image —– of course, 110 lens costed me only few pounds as a junk, in contrast Zeiss was £800 even for a second-hand = be humble, don’t expect too much)    😀

PS : Looking around the Net-sphere, it seemed that the news of naming the new era in Japan took so much attention from all over the world.   The tradition to name the Era originally came from Han dynasty of China though,  like most of the culture in China it ceased to exist under the communist rule.  (So that the young Chinese except Taiwanese, even can not read their own classic literature like Laozi 老子, Confucius 孔子 — let alone to understand them)   Yet still, as nearly 1/4 of world population is Chinese, some of them might have studied classic, hence able to read the “Chinese” character 令和 of which the meaning is more or less the same to us .   (Some character’s meaning is quite different between Chinese and Japanese = such as for flowers, Chinese use 華 , Japanese use 花 but for Chinese this letter 花 mean mor like a lot of mess, therefore 花子 in China mean a beggar wearing tattered rug. — without knowing this, quite few Japanese girl got their name Hanako 花子 ! )

The meaning of the character 令 is “telling or announcing” = so that, with an additional 金 (metal) to its left hand side, like this 鈴 it’s become “Bell”

And the 和 mean “come together or harmonize”  so that a word 平和 mean peace ( 平mean “flat or plain”) = Everybody come together in harmony” is a Peace.

Therefore, 令和 Rei Wa mean, Calling a Harmony  or Telling, be in Peace”.  (May be not as strong as “Shut-up, you the Devil”)   😀     (By the way, officially Reiwa starts on the 1st of may, coinciding with the new Emperor to take the throne.   This, one month ahead schedule was for the people to prepare such as for printing the calendar.)

Few more photos of last Heisei days

I’m living in England though, still it is the last moment of Heisei Era for me.

I’m a Japanese, yet I’m more like a spooky kind than an Anime generation.    And never be a Gamer of Gandam kind.

Or a dirty old man ? —– It’s quite a questionable.  

Then I found, the local Iceland shop was closed. —– I don’t think it’s anything to do with the end of era in Japan.  (Don’t you think, this is THE good lens = instantly giving 50 years old atmosphere to the picture !)   😀

And found that the Small White Elephant Cafe was also closed. (Before the end of financial year ?)

Those photos were taken by the homemade ZM2 lens or Pentax 110 24mm F2.8 lens on the Nikon Z7.

On the end Japan got their new name of the era as Reiwa (令和) —– long live to them.    🙂   🙂   🙂

Japanese New Era is coming

Well well, not for tomorrow’s April fool, but Japan is going to have the new name of the Era for coming new Emperor.    Japanese calendar system has the name of each Era with each Emperor’s throne.  Which is the continuing tradition of the past 2500 years, started on the time of the legend of Emperor  Jinmu.  So that the coming new Emperor Naruhito is its 256th Emperor.  = in other words, the current Emperor Akihito’s (He is going to cede the throne to his son Naruhito on 1st of May)  Heisei Era will end tomorrow.  (I remember the day, when I went to see the wedding parade of Prince Akihito and his bride, Michiko in their hose drawn coach. — I think I was a secondary school boy then) 

—– anyhow, on this last day, I should clear the stacked photos of Heisei while it is still in its era.

(Those photos were taken by ZM2 lens and Helicoid B lens on Nikon Z7)

On the end Japan got their new name of the era as Reiwa (令和) —– long live to them.    🙂   🙂   🙂

Useless thought — is it ?

While boiling the eggs, I suddenly heard a noise “Pang”.   I knew it must be a noise of the egg cracked, as time to time they do.   When I checked them, I found an egg popped open a part of its shell, like a submarine opened his hatch = a well made round hole. —– I’ve seen hundreds of the cracked egg when they were boiled “in my life” though, I never seen the Egg Submarine opened his hatch. = this is THE first event ever I encountered and witnessed in my whole life.    is it ? ? ?  —– So, what’s the matter ? 

———- Then I realized, this is the serious identity crisis case.  It would shake the foundation of the cause or justification of me to blog here. —– How and why this blog started ?  = This blog / Yoshizen started as a talking post to explain my theory, that is,  The Zen is not for talking or thinking but to DO.  This theory was conceived through my own experience of doing,experience of doing, and from many stories how the one could achieve his skill by just doing it many years kind, and the old say, such as even Rain drops carve the rock kind together with the very simple facts that the most of Buddhists sects are having their practice to repeat doing the same action.

—– So far, I think I succeeded to explain those matter by explaining them as the function of our brain / Amigdara. 

But, what about this instant case / Open hatched Egg ?     What this egg to do with Zen ? —– Quite few of the posts here are showing a kind of activity, demonstrating the simple, repetitive work for “Making something” also showing the sample of the way of utterly free thinking.  (why not approach, such as to use a spray can as a barrel of a macro lens or a discarded drink-can can be made a good sculpture etc. )

But is the Open Hatched Egg to do anything with the Zen ? = nothing.  Why not ? (Everything is the only an occasion in the life = have you ever seen any of two eggs cracked and showing exactly the same pattern ? —– Does the Zen Blog got to have a special big topics to talk ?  —– am I assigned to deal with such heavy role ?  —– who the hell yoshizen is ? = It must be a joke = can not be such ostentatious matter here.  it’s just a small free blog.  —– What an useless thought I got here.     😀

Sony Lens Mystery (2) — After Sony’s answer

Sony2-Test

On the time of the first discovery of the strange phenomenon, inside of a Sony’s 30mm Macro lens, I gave an enquiry to the Sony.   And I got an answer from them which said :

“With reference to your enquiry and after further investigation, we would like to highlight that the Sony lens does not have a special technology used. Therefore, the focus resetting does not have to do with specific technology used inside the lens.

SONY SUPPORT TEAM
http://www.sony.co.uk/support/en “

As they didn’t answer why and what for the lens focus move, I check the lens and found that even after more than 10 days, as I haven’t touch the lens (and the lens hasn’t been mounted to the Sony body = battery or super-capacitor if there was any at all inside, must be exhausted) the focus still moves.   So, I further gave them an even harder test, “with 10 mm extension ring”. (photo top)

Z7+30Macro+10mm

On Nikon-Z7, the Sony SEL30m35 lens + 10 mm extension ring made quite a good close-up images and this was the closest I could go. (photo left)   And a bit more distance, lens worked almost on AF mode. (photo middle)  Then — while lens was kept aimed to dark object, I suddenly moved the lens (camera) to bright outside = the lens focus moved to far (photo right) then back  to very close.  M m m ? ? ? —– wait a moment, the LENS got 10 mm extension ring too.    How come the focus to far subject like the photo right here was possible ?    What kind of optics can override the 10 mm extension of the focus by a little movement of the lens ! ? ? ?    It’s incredible. 

Sony+10mm

So, I did test the same on Sony A7R body.   The result was as you can see on those photos.  = With 10 mm extension, the lens can give only very closed images (photo left) and the middle and the right photo.

With a bit of cynical view, this lens SEL30M35 (30mm Macro F3.5) can give more on the Nikon Z (with my special adapter) —– than on the genuine Sony body.   😀     What ever the Sony says, the lens keep move the focus while detecting the own position without power, as if its got own mind.  This must be their special technology used inside of this lens.   So, the mystery was not solved at all.   😀 

(Sony might got quite a confidence to ignore a funny question, even after the Canon and the Nikon came into the full frame mirrorless market, Sony’s share is still over 60%.)

ZM2 Lens – Spring Walk

First visitor here tonight was from USA, seeking Plum Flower.   So, I’ll show you many Cherry flowers, Plum Flowers.

You may not believe though, all those photos here were taken by just one lens,  (homemade ZM2 lens, on Nikon Z7 camera — ISO 100, AV setting)  Slight difference of the focus, the lens can produce quite different kind of image !

This plant called Japonica Japan was originated from Japan as its name suggests, and a cousin of Quince, or relative of Pear.   Incidentally, a name Nipponia Nippon which meaning is the same (Nippon is the formal name — Japan is a nick name after Marco Paulo) was for national birds Toki who has been nearly extinct and revived to about 150 now.

Ever cute Snow drop, Japanese name is Yukiwari-so (雪割草) which mean the flower who sprout out the snow !

I found this variety of cherry first time in this country.  Still no idea of its name.

And this is somewhat close to the plum. (But not Japanese Ume 梅 —– I don’t know why Ume didn’t come here.)

And this is Daphne —– somewhat related to Cloves though, the story was very complicated = lots of misunderstanding.  (You might have seen a furniture made by a wood called Mahogany but never know what its tree looks like.) 

Same as that, the wood for burning incense Agarwood 沈香 was a mystery to the Japanese for many hundreds of years, and people mistook this plant was related to Cloves 丁字 (hence Japanese misnamed this Daphne as 沈丁花－－－on both case the letter 丁 represents the shape of nails which is a shape of the Cloves as well and the smell of this flower is the same to the Cloves though) those plants are in fact totally different plant. 

Since Agarwood can be sold for very high price, the tree has been pushed to near extinction = now they are protected and the genuine wood is hard to come by, so that, there said to be a lots of fake in the market. ( = a wood dripped into an artificial incense was sold to the tourists.)

Crocus is a relative of the Saffron.  (So, don’t eat them)

(In fact, Daffodil is also poisonous — if you eat = Who eat ?)

I guess this cherry seems to be originated from Yama-zakura.  — but not sure of its multi-petal flowers.

So, it was a nice walk and shootings.

Those three photos were somewhat an extra.  I met Ms.S and Mr.M as a next door of one of the cherry flower’s place.  They got very fancy bicycle with motor. (And those photos were for them to copy from here)

Go out with ZM2 Lens (First field test)

It’s a rare bright day.   And the spring is coming.  (Olegon Maple started flowering)

I didn’t know there was a gallery here. (but not open today ?)

It’s hard to tell whether the aberration of this lens, ZM2 is coma or astigmatism ?  (The camera was Nikon Z7.)   Do you want to see this photo in normal sharp image ? I don’t think so.  This is what this photo should be.

Is it an image from a dream or nightmare ?   Or, premonition ?

The difference of those two was just a slight move of focus. (Since the DOF was so shallow, slight move suddenly makes the image collapse. )

You might be wondering, how such hopeless lens can still makes decent image in the same time.  (That’s why I said peculiar and I like it very much.)   😀

Peace to everybody.

.

ZM-2 lens (Second version)

———————- (ZM2 sample photo —– fake  stage up)

There wasn’t so much complaint to ZM lens —– still, give a thought or two = even though I said most peculiar, the reality was not peculiar enough, just another mediocre lens. 

Before, while experimenting with the lens, I noticed that this lens can produce much more aberration when it was reverse mounted.  =  So, why not. = I further modified the lens optics made reversed.

The result was, some may say, a lens impossible to use.  (Somewhat comparable  to the Helicoid-B lens which got strong astigmat aberration ) Yet still, this might be what I needed.  (What’s wrong ? )   😀    (as you can see from the photos, DOF is extremely shallow, and showing very heavy coma aberration.   This lens was about 45mm F2 equivalent, fully open, still if well focused, image looks quite sharp.) —– now I need to find the suitable subject.  (I hope the subject wouldn’t be frightened and runaway )    😀

Is it peculiar enough ? (just a bit off focus)

And this is well focused (so far).   😀
