Since I obtained some Focusing Helicoid, I’ve been testing their best use etc —– so, while testing 36~90mm Helicoid with old antic lens, watching the tree, I saw a squirrel on there.


The lens, originally for a Kodak red bellows Folding Camera, was mounted on an extension of a helicoid and working as a 175mm F10 telephoto lens. (Pretty dark)


I don’t know what the squirrel was doing there, I just snapped a busily moving squirrel. (Though don’t ask fine focus to 100 years old dark lens on an awkward helicoid. — this must be an optimum result for an inpromptuous handheld shot.)  😀


(And I don’t think this photo is showing any good quality —– never mind If I needed I could have used proper Lens. —– and I wouldn’t insist “fuzzy image” for this kind of picture ! —– You can see properly photographed catkin’s image.)



What on Photography


Although it was a bit cropped, still this was a quite wide-angle view (18mm) of a morning sky, and this was more or less the view what we are actually seeing = in other words, this IS a faithful representation of the view = and that was what we expect to a photo.  —– So, the Photo IS a COPY of the subject, therefore if the subject wasn’t there in the first place, the Photo couldn’t exist neither.  And may be because of that, the Photo competition prohibit the Photoshopped photo.   Photo has to stay as a faithful secondary image of the subject.


And this is the image of the same sky, taken by the other camera at about the same moment of the photo on top.

So, this is a tricky situation. This photo above may be seen to be an illegal image using a ready-made digital effect, so-called “Filter” such as in a smart phone.


But this is the natural character of the lens.  From the common sense, this images may not to be regarded a Photo still, this IS the image, straight out of the photographic device / camera.  (Downsized to 1200x*** and collaged by Picasa in my XP laptop)



They were the images out of Sony A7R with so-called Helicoid (B) lens. —– If the photography was a mean to express oneself, those photos may have my feeling which evokes much deeper into your subconscious.  And they were not by the ready-made effect but only one of the kind in the world. (Whether you like it or not.)   😀


Helicoid Lens (B)


Helicoid Lens (B) is a sister of (A).  Both came from the same Sony Zoom lens and I’m using the same size helicoid which I got from China.


So, this 18~200 Zoom lens became the SZ lens and the Helicoid A and B.  Well done.

Helicoid-B(3) -004

Lens was tested while temporally fixed on the camera using plastic pate, such as whether the lens should be used reversed or not, and with smaller Iris etc. (Photo middle) In order to adjust the infinity, lens was fixed on a M42 to M39 adaptor ring on the M42 to AI (Nikon) mount adaptor. —– after the infinity point was found, the position was fixed with super-glue. (Photo right)


It seems this lens was an aspherical as the funny shaped reflection on the surface suggests. (Photo left)  This helicoid extends from 17mm to 32mm and the Lens which got about 35mm focal length can focus from infinity to 15cm close-up.  And the calculation from the exposure reading, the brightness seemed to be F2.2.


Though, this lens is having very strong aberration. ( Astigmatism ?) —– same as the Lens (A), the center wasn’t too bad but image quality was one of the worst = which I appreciate a lots.  😀     (It’s so rare to find this kind of image in the photography because, nobody design the lens like this for sale.)


(Photo here above, Left was the (B) lens in its finished looks — looks cool isn’t it ?   😀  And the right showed the Lens’ closest view, which showed its softness for comparison.)

For impressionistic fuzzy image, the poorer the lens quality, the image looks more interesting. (I think / and that was where Pinhole Photography stands) —– strangely, the close up image was rather sharp. (I mean its center was) (Photo right)  —– Whatsoever, I’m quite happy with its outcome.   😀


Helicoid Lens (A)

Helicoid Folder(1)-DSC08423

While hibernating in the winter (because, I can’t go ski kind, let alone climbing the mountain, = still have to do something — I made yet another homemade Lenses. (this time using a focusing helicoid sold in the net.)

Helicoid Folder(2)-003

In the political stance, I should re-use other old camera’s lens barrel kind though, they may not come when I want.  So, I bought some focusing helicoids from China such as 12~17mm, 17~35mm, 36~90mm, mostly M42 fitting.  (M42 rear mount / Pentax screw mount can be easily converted to Nikon, Canon, Sony-E with a simple (and cheap) adapter.)


And the lens I used was came from broken Sony zoom lens. (In the center of the photo above, two of the small lenses)

Helicoid Folder(4)-001

So, the game starts = how to fix a small irregular shaped lens to the helicoid.   In here, cut a card-board paper to the shape (Photo left) and mount into an empty filter ring (Photo middle) — and 52mm filter ring was mounted to the helicoid. (Photo right) = to test and check if the infinity focus can be made. —– (this approach failed)

Helicoid Folder(5)-002

And in here, another lens was temporally mounted on a helicoid with soft plastic patty (Photo left) —– Photo middle showed the lens on the previous photo was screw mounted to an aluminium ring which was epoxy fixed on to the 52mm filter ring, and to the helicoid, then to the camera body. (Photo middle and right) —– (For clarity sake, those photos were taken before the mat-black paint was applied

Helicoid Folder(6)-00

This lens, with about 65mm focal length has an Iris ! —– though, the image made by this lens was too bad (except pretty good center) and the effect of the Iris was not much help.  😀

Helicoid folder(7)-Fullmoon-31-01

So, they are the images. (Looks hopeless coma aberration)

My attempt to make homemade lens has been having funny paradox, while making the lens DIY, the image quality was just fuzzy and poor, —– yet still, I’ve been trying to make it somewhat usable. —– ? ? ?    Then the “Enlightenment” came which was “Why not”  It IS the nature of the lens = bad lens makes bad image.  What’s wrong ?  The top photo here was made by this, Helicoid Lens (A) —– I think, this bad image was not too bad.  I like this painterly effect.  Don’t you agree ?  (It seems, the Japanese Zennists are visiting here.   So, those “Play with lenses” are also the demonstration of the “Mind game in Zen”=  “liberate yourself from a stucked mind” “Why not”    Ha ha ha.   😀 )


Blue Moon without Eclipse


It was a Full Moon, but we in England couldn’t see the Eclipse like somewhere else could.     Never mind, it won’t cause any misfortune.

(As always, the photo here was taken by Tamron SP Mirror 500mm F8 on Sony A7R. Through double glazed window.)  😀


Dance Dance Dance !

May be because I’ve clicked the Spanish Flamenco or Japanese Awa-odori dance kind before, time to time, Youtube send me the dance viz —– so, I’ve encountered those amazing dance viz.

In this viz above, the first group was Doushisha-Kouri Hi’ and the second group was Osaka Tomioka-Hi’ —— Yes, they are all Hi-school girls.  First group was performing the dance,  titled “Black Rose” in black costume.  Then the second group was dancing in the 80s Disco style.  Those two were the top of the many hundreds of the entries of Japanese Hi-school Dance Club Annual Competition.  Lots of the club members may never dance before = It’s mean, to train the members in Three years to this level must be nothing but a phenomenon. — (A story behind told, that they practiced up to Nine hours a day ! —– Some comments to the viz described “like a Ninja” = Yes, Ninja was created in the same way = They were all under the same Japanese Zen Culture !)

Despite Tomioka got only second in last (2017)  year’s National Competition, once their viz, “Babbly Dance” was uploaded on to Youtube, it spread through SNS, they received 30 million hit and created a hype in Japan. ( So, they were invited to dance at “New year’s Eve National Song Fest/ 紅白歌合戦 on NHK” = for the hi-school girls to appear such National fest was the exceptional honour)

I admire the intensity and the speed of their body movement, though I wouldn’t dance in that way.   They dance very physical though, their movement was a staged, visually choreographed style for show = not follow a natural body dynamics.   It’s mean, if they were pushed while dancing, they will be easily toppled.  I took the basic body movement from the ski = if we lose the balance on ski, we will fly in the air and land 10 Ms away.    So, I’ll keep the center of the movement always in the symmetry to the center of gravity (so that I can hit or give a kick in any moment without losing the body balance as the body itself having the counter balance.)

One girl was saying, “Don’t think. Just keep doing until the body start to move automatically” = this words were the same as what I’ve been writing here, “Don’t think = Mushin” is the key in the Zen practice.  When their body start to move automatically, the ill-balanced artificially choreographed movement would be smoothed out.  I think, while doing such intense training, those girls would gain much more important “Natural dynamism of the body” which will be the key for their happy, healthy life for whole life.  Well done girls.




Piece of Art

I’ve just received a mail, large air-bubbled envelope.  And I discovered a content, a piece of Art which could have been packaged in a heavy wooden crate.

Art-top5It’s from a daughter of my friend, who started a fine art study, whom I gave a pinhole photo device. —– As a return of a 0.2 mm void on a beer-can panel, she made pretty unique image of a master piece for me.  (It’s a proof of that, a 0.2 mm void could have a trade value for could be a priceless master piece though, don’t take it for a precedence, it may not work for your case.)   😀   (A void created by a Zen master could have a significance, comparable to the whole universe.)   Believe me.   Ha ha ha.  😀

Morning SKY – 18

N_SKY(1)-DSC_0357Took on 18-01-2018/02:41   (This photo got funny reflection of the room)

England was having only +9° weather and severe gale force wind, nevertheless the life goes on and as usual, still, a morning is keep coming.

N_SKY(2)-DSC_0358/6:45 (ISO 800, 2 sec)

Looking out the window, I noticed rather fancy sky.   (Except the last photo, all the pictures here were taken by a Nikon mount Zeiss 18 mm lens / on AV mode)

N_SKY(3)-DSC_0359/6:47 (ISO 800, 2 sec)

On front of my eyes, the Sky changes minutes by minutes.

N_SKY(4)-DSC_0360/6:49 (ISO 200, 6 sec) —– When those 6sec exposure occurred, the camera was hand-held, while the top of the lens was pushed against the window glass.  😀

N_SKY(5)-DSC_0361/6:54 (ISO 200, 6 sec)  (Notwithstanding its hand-held 6 second, the picture was surprisingly good. —– don’t you agree ?)

N_SKY(6)-DSC_0363/6:56 (ISO 200, 6 sec)

N_SKY(7)-DSC_0364/06:59 (ISO 800, 1.3 sec)

N_SKY(8)-DSC_0365/07:01(ISO 800, 1 sec)  (The light in the each picture was a different aircraft —– so many of them flying)

N_SKY(9)-DSC_0366/07:09 (ISO 800, 1/3 sec)

N_SKY(10)-DSC_0368/07:32 (ISO 200, 1/20th sec)

N_SKY(11)-DSC_0372/08:04 (ISO 100, 250th)

N_SKY(12)-DSC_0374/08:33 (ISO 100, 640th)

At last, the sun came out.

N_SKY(13)-DSC_0375/08:36 (ISO 100, 80th)


(Only this picture was taken by a homemade G9 lens on Nikon D850.)

Birthdays Party

birthday Party(1)-DSC_0278

There was a kids and grownup’s joint birthday party among the member, ex-member of the Dorkbot / Spacehijuckers.  Where it took place in the notorious Lime house Town Hall, where the lighting was notoriously awful pink light. 

birthday party(2)-008

Made a situation even worse, I took pictures with a notorious homemade SZ lens and the 40 years old Nikon fisheye lens on Nikon D850.  And the result was what you can see.

Somebody started to do a clay craft, try to show their creativity.  —– Following the foot step of Marcel de Champ I made a toy size urinary = great attempt (I think).

birthday party(10)-004

birthday party(11)-001

birthday party(12)-002

birthday party(13)-00

birthday party(14)-007

SZ lens is about 100 mm F1.8 though, as it doesn’t have a clear focused point, it is not easy to use, especially under the dim pink light.  😀   (Of course, their  lighting can be set to neutral white though, if it was their choice I have to follow.   (Or, I should have brought own my light.) —– don’t worry it was just a party.     Happy Birthday !



Omuni-focus Lens

Omni lens(3)-003About a month ago, I talked about Halina camera and its lens. —– A story how I made its lens to use on the Sony A7R camera and showed its sample photos.

Omni lens(2)While checking those homemade lenses, I found that the said Halina lens could, (with an additional diverging lens on front, as its focal length become longer) be used with a thicker Nikon body.  So, I further modified to add a diverging lens and mounted them on a 42M (Pentax screw) to Ai (Nikon) mount adapter. = Here I got Omuni-focus lens for Nikon DSLR. (And this work was somewhat related to the other lens)

Omni lens(1)-001

I know, this situation is having a silly contradiction.  Why 47.5 MP Hi-Res camera need such low-Res images ? —– Omuni-focus mean, nowhere having a “Distinctive OUT of FOCUS (Bokhe) image” in the same time, no “Clearly Focused image” either.  = Just rotten images spread from top to bottom. ( More like a pinhole photo ! )   

A_Omni lens(4)-006Yet still, those photos above, both far and close subjects, it is a rather remarkable phenomenon, such a cheap plastic lens can make (a kind of) usable image in any distance, without focusing, without using smaller F-aperture.    (BYW, the last dried rose was taken with an additional close-up ring) = Omuni-focus is not necessary an almighty.)

A_Omni lens(5)-007And those comparison photos were for academic interest.  Left was by this Omuni-focus lens, and the right was in deed, a pinhole photo image !

Now, my point must be clear, not necessary only decent sharp image could be a good photo.  (Though, I’m not implying my fuzzy image here IS a good photo.  😀

Omuni—– May be not a good photo still, I found that those fuzzy images appeal to our deeper psychology. —– I had distant memories in my subconscious, I might have seen this long long time ago —– may be even on my previous life ? ? ? )
