Ultra Proxer — Recycled from Old zoom lens
Proxer is an old name to call Close-up lens which attach on front of the lens.
The lens I’m talking here is a front lens element I’ve scavenged from an old zoom lens 85~210 mm F 3.8, sold under many different names —– the photo was in the previous post (first photo, Front lens was near the left end).
Most of the close-up lens consist simple convex, single meniscus lens mounted on a filter frame. Same idea to put a magnifier before camera lens and take close-up photo. It was convenient to have a small adapter lens to take closer picture, as in the old days there was no such things like a macro setting on the Primary lens (Standard lens).
—– To make a high-performance Proxer, I did some cut and bonding works with epoxy glue, which was worthwhile to create a treasure out of junk. 🙂
Photo left : Don’t hesitate to hack-saw a lens barrel. Once disassembled and the glass was removed, even a precision optical device, is a piece of metal. = What it used to be is only in your mind. On this moment you are dealing the work to create something new. What required here is a careful but very simple and boring push and pull work. 😀
Center photo : To the front lens, hack-sawed front barrel (which got 58mm filter screw ) was screwed back and a filter ring was bonded to its rear side with epoxy glue.
Photo right : The finished close-up lend was attached on the front of the Canon EF 100 mm Macro lens, which also has 58 mm filter size.
You might be wondering, while having macro lens already, and having a skill to use the lens in reverse etc. = all sorts of close-up trick, why do I need to have yet another close-up lens. —– well, all of my Macro lenses were down to the life-size, in other words, they take a picture of 36mm x 24mm is the closest. I simply wanted to close a bit more. (My attention tend to go rather small things. 🙂 )
—– And a real intention was to have much more exaggerated out of focus Bokhe. (I’m tired with clear images which is everywhere and too easy to come by today.)
Photo left : With this close-up lens, when the master lens, 100 mm Macro lens was set to the infinity, a small dole (36 mm tall) looks like this. (taken F 2.8)
Center Photo : With close-up lens, when the Master Macro lens was set to the life-size, it produces x2 larger image (dole’s head is 10mm). Have look the Bokhe in F 2.8 = max open). (This Bokhe is quite close to the Olympus Zuiko 50 mm F 2 Macro lens ! )
Photo right : A small beetle who happen to came to my room (it’s too hot these days, the window was fully open) this photo was taken with a bounced flash-light with F 11.
Unlike most of the Proxer, this home-made close-up lens has double lens chromatic structure, and fully coated. = Think, a cost of common cheap Proxer, and a Front lens which is the most crucial part of the lens structure in a zoom lens.
= Difference of quality is obvious. As you can see it in those sample photos.
A photo of a moth parched on the wall in my room, taken by EF 100 mm Macro with the handmade Proxer. = With F 2.8 the depth of focus is really shallow still, in the focused area, the image is very sharp.
This is a test shot of the screen of a Tablet (a photo of my umbrella). This close-up lens maintained very high quality of the image = Very even, corner to corner. And this is at F 2.8 ! (See details, by click it, and again)
Left photo is Macro lens alone and about 1/2 size. Right photo is, with close-up lens but Master lens was set to Infinity. Hence this combination can take photo from infinity to 1/1 and with this Proxer to x2. (By the way, Canon 5D mk-III has dreadful red-color cast when ISO was set to 6400. In AWB and in any setting. Though, at ISO 100 much better. = See the photos below)
(Photo left : 5D but Mk-II. Photo Right : The ISO setting was 100 = Much better !)(Those are hand-held photos = only for Color reference.) To be fair, I show you the photos by Nikon D810’s color in similar setting.
(Photo Left : Nikon D810 — ISO 3600 Photo Right : Same but ISO 100 Both with Micro Nikkor 55mm F3.5 — 1/2 )
Higher ISO setting mean, very low out-put of image sensor has to be amplified electronically to its limit. While amplifying to such extent, still linearity has to be maintained, while the out-put of each BGR may not having exactly the same character.
= Can of warm is opened. 🙂 In the same time, higher amplification also amplify the noise as well.
—– I admire and praise the people who managed it and brought the benefit of very high ISO setting even if it was not (yet) perfect.

Junk Lens — How to recycle ?
After digital revolution, analogue age old lenses become almost a junk.
Simply, the camera and the lens today are too different from their predecessor.
As the lens has to work with the camera which got so many functions therefore
the lens also needs to function such as auto focus, electronically position controlled
F-aperture, distance-coded focus not mention high zoom ratio, of which the zoom
position was also electronically coded. (Those code were used to control Flash-light)
= In order to deal with all those electronics, the lens having its own microchip and
able to communicate with camera’s main CPU.
Without having those electronics, lens couldn’t be used on the camera —– except
Canon EOS (It can take any lens include a Pinhole in AV-Mode, of course with
manual mode as well. — But, Nikon couldn’t make even a single image out of pinhole,
without giving quite complicated procedure to set-up the camera side. )
Though, don’t misunderstand, even today, the optics is still optics, it works on the
same principal, hence if you get a convex lens and concave lens scavenged out of old
camera lens, it would make a telescope for a kids to experiment. Or use them to project
an image or focus LED light etc etc.
[]
The lens design has also changed a lot such as the use of aspherical lens (in fact most
of them are a so-called Compound lens, aspherically moulded plastic was stacked on
a glass lens) —– nevertheless, I admit, today’s lens is very well designed in deed.
(Though, why they became so big and heavy ? — considering, how compact camera
became so small and light, while able to take more or less the same picture. 😀 )
In those aspects, may be there is no point to give a damn to the old lens though, still,
such as F-aperture diaphragm has changed almost nothing (only driving mechanism
may have changed to motor etc. And the front lens is still, good achromatic lens.
Not mention the focusing helicoid which is impossible to make by ourselves, still
having lots of use, not only in the photography.
= We can scavenge a lots out of such old lens. —– As a matter of fact, good old
non-plastic lens is far easier to disassemble and Re-use. (Plastic built lenses were
NOT designed to be serviced as they were built by snap fit or heat-weld.)
(Lens above is a Canon TV lens, it must had a price of many thousands of pounds. )
The best thing is, we can find those old lens in a camera shop’s junk box,
with a price of couple of pounds, if not free.
To disassemble those lens, there may not need to have more than small
+ AND – screw drivers. (but need to use the brain a lot = it is a puzzling game)
In coming posts, I’ll show you what I’m going to do with those “Components”
saved from old lens.

Flying Angel — Wire Figure
This is my Angel, yet another wire-figure I made on 2007. (So, those photos were
taken by that old Kodak camera, and the photos were clopped —- hence, pretty low
quality photos) But not PSed, the figure was really in the air (hanged from the tree).
When I brought this to a gathering of Dorkbot, the figure made a well known artist
Anne Bean, frozen 5 min—– ( I was frightened, such good artist can memorize all the
structure and able to make identical copy 🙂 )
Strangely you may found, this lady has no neck. Her right hand holding the head. 🙂
Wire used was 1.6mm garden wire, and I was planned to make it x5 size, it’s mean
life-size, by 8mm copper tube though, I realized that, if I made this in my room,
I can’t take it out 😀
—– One day, when I got big studio, I’ll do it (though, seemingly never happen 😀 )
[]
Development of Foetus
Well, I meant not a baby but wire-Figure in Foetus Posture.
Unlike a body posture spreading limbs, Foetus posture might be more awkward to
make sense, because it might become just like a pill of wire. —– So, I tested how it
could be made simple and still convincingly looks like a human-figure. — The first
study above was made its back and the legs separately, so each did look “likely” shape.
(I found, in Foetus posture, it doesn’t need to have a head —- We think head was
buried between the shoulder. 🙂 )
Then, the second attempt was how to reconcile the joint of upper-body and the legs.
—– This one was not successful or smart enough though.
The head was accommodated in the third model.
Looks not yet streamlined enough —– though,
so far this is the final piece called Foetus.

Drawing with Invisible Force
[]
This is a wonderful watercolour drawing by Elene Caravela, which I found in her blog:
elenacaravela.wordpress.com (Quality sake, please see her Original Drawing there)
Elena has been one of the most prolific artist and the blogger who showed Watercolors, Oil paintings,
Photographs = very wide coverage of genre in very high quality work.
In the past year or so, I always impressed, even amazed by her drawings,
how her almost whimsical free blush strokes able to capture such vivid and also
realistic human figure. —– What is the secret of her creation ?
[]
To my comment and a notice that I want to re-blog —– she gave me her reply ;
[]
I’d be flattered Yoshi. I guess, I plan in my head a bit to make sure the figure will fit on the page
(mentally count out head size both vertically and horizontally, but really loosely).
Then see the movement on the spine and extremities. The force takes over.
Sometimes it works, sometimes it doesn’t 🙂
[]
—– As she said, she might have given some consideration to the size of the
head etc. = here the thinking stops, then “the Force takes over”
To see her blush work, there is no hesitation, its quick movement some times creates even
the paint splash or drip. (in another piece) = blush and the hand moves perfectly spontaneous.
So, —— in such spontaneous blush stroke, look again the drawing above, = one blush stroke
perfectly depicted the body-line to the round bottom. — I guess, here not only the
direction of the blush movement, also it involved certain control of the pressure to the blush
and its twists, which determine the width of the line. (though, only a guess — I know the way how
to use curving chisels but not necessary the drawing blush 🙂 ) — all in the moment of one stroke!
This phenomenal control was done by the invisible Force, not possible by a human thinking.
[]
Spontaneity mean, there is no intentional control or thinking. —– This is nothing other than what
Lord Buddha taught = the state of Selfless / Mushin, therefore “The Force takes over”
= this Force is what Buddhists call the Dharma ! (or the Rules of the Universe)
The moment when the blush and the subject meet, the tension and the heat created
on that moment, drives the blush wild. = and creates dynamic impressive piece.
(consideration or useless thinking such as what others or market may think etc. spoil the tension
and the heat, hence makes the piece dull)
But Elena got perfect freedom not bothered by useless thinking, and I guess, when her blush was
driven by the Force, even she, herself may not able to control = blush got its own mind and move
almost automatically. That is how she creates such impressive work = It’s wild, as it was driven
by the Force of artistic nature. 🙂 That is what the art of Elena stands out.
[]
By the way, don’t get me wrong, I’m not implying Elena’s work is anything to do with Buddhism.
Far from it, the state of Selflessness is one of the inherent human psychological nature.
Buddhism applied it to more general aspects of the life. Not only the superb blush work, we can
achieve the superb life with it. = Quite similar to that Love is not because of the Christianity, but
they applied it to much deeper spiritual level.
Zen Buddhism pushed the potential of Selflessness to its extremities.
—– That is what the Zen Buddhism is.
[]
Elena has acquired this state of mind while drawing / practicing again and again,
probably tens of the thousands of times. Hence, the Buddhism using the same way of
the approach = practice it again and again until the hand started to move automatically.
= Hand moves automatic = without thinking = without self conscious = Selflessness.
In the Selflessness, invisible force takes over. This force is the Dharma. = Under
the control of the Dharma, phenomenal freedom and the result can be achieved.
This is how the Selflessness in the Zen Buddhism works.

Handmade Flash System (3) — Macro Flash
In the close-up photography, the exposure was a headache before the TTL metering was invented. Still, the use of flash-light remained yet another headache —– until TTL auto flash-light was developed. (When the lens was close-focused, effective F-aperture changes logarithmically (= life-size shot darken 2 F-stop, unless the lens was designed using internal flow focusing system) and the flash-light intensity changes in distance also logarithmically ( = brightness on 0.5m is x4 brighter than it was in 1m distance) Yet still, in practice, even those TTL flash-light was not necessary convenient to use for the close-ups, as they were not designed to be used in such close distance.
In the other hand, lens has been well advanced to have even extreme close-up, almost to the lens front though, in such close-up position, the big lens front block the light to the very subject.
= flash head has to be positioned, close to the subject.
[]As a matter of fact, close-up photography and its equipments are the cash-cow of the camera manufacturer. = The most of the people who “need” to do the close-up photography is the public institutes, doing scientific research or even police forensic photography etc.
Therefore, they pay the equipments what they were asked —– anyhow it’s not their money. (hence, they are so expensive, and creating so much profit.)
And in those scientific photographic front, the use of flash-light was much more preffered over other light-source such as tungsten light, because of the flash-light has no heat problem, and the xenon flash-light contain much more UV or near UV light which is often used for fluorescent effect of certain chemical, hence extremely important for forensic and medical photography.
[]But for a poor man on the street, those Macro Light from camera manufacturer is too expensive, even though, structurally they are not so special. =
So here, yet again, comes the same motto, WHY NOT make it ourselves.
(Though, here is a very strong WARNING ! Electronic flash is a Hi-Voltage lethal device, even if it was powered by batteries, some of the parts, inside are having more than 300V. And in operation, when it was triggered, some of the lines carries 3~4000V ! = Unless, you are very experienced in Hi-voltage circuit, I wouldn’t recommend you even open the housing of flash.
—– before handle, the capacitors has to be completely discharged through 1K, 5W register) ( I got many experiences of repairing studio-type flash, up to 5000WS, which discharges 1200V and handmade 600WS studio flash for my use. —– I’ll show it to you in another post.)
[]This macro flash was made with an easiest straight approach.
Just take the flash-head out and devised it to mount on the lens front that all.
Still, it rotates (and fixed) any position on front of the lens, and the head also rotates in two axis hence it enable the flash-head aiming to the subject, or rotate it upward and a paper stack to its head would make more natural diffused light as well.
The base of this modification was Nikon SB18 hence it works perfect as a TTL Macro Flash with old F3, FEII, F801 etc. etc. though, as Nikon changed the design of their flash control system in their digital camera, this one doesn’t work with such as latest D810.(so, the photo above may be misleading. 😉 ) May be I should make the same using their latest and cheapest flash. (in fact, structure of the flash head is all same, only 3 cables connected to the tube, I can connect this head even to a Canon flash.) ( So that, the photo above is just an illustration of mechanically “how it was constructed” and no sample photo of how this Macro Light works 😉 )
[]Funny story of this was, when I showed this to the Nikon (UK), their boss Mr. Obara was annoying so much and said “How come, you buy such cheap flash!” but their engineer was burst into a laughing “Yes, this is what all about the Macro Flash in deed” and said “You got far better skill than our prototyping engineer” —– though, it was 1986, just before my trouble started. Then I gave-up my photography, and most of my possessions were gone to storage if not sold, hence, there was even a single photo done by this flash ever existed. So that, when I found this in the bottom of cartoon box, I felt a bit of amazement and the sadness. —– One’s life has all sorts of twist and turns in deed.
(Yet still, I’m glad, my fun loving creativity and the skill on my hand didn’t die with it.)

Handmade Flash System (2) — Light Bender
As a matter of fact, this is my first Digital Camera. It was a broken Kodak DC215 Digital Zoom camera
which was given by my friend as its battery chamber has been smashed.
So, he gave it for me to play with. Lens was x2 zoom (29~58mm equiv) and Image sensor was 1.5 MP.
( In today’s standard, it is a toy camera level though, 10 years ago, it was rather expensive good
camera 😉 ) Since the camera has been dropped and a corner of it has been smashed, I was not
sure whether it was repairable even if I get spare parts from Kodak. Still, with internal check, the
suspension mechanism of Zoom and Focus was not broken, I tested it with external power supply
—– it was functioning ! So that, not just repair the battery chamber, instead, I made an
additional battery housing attached to the bottom of the camera to use it with
5 rechargeable batteries. (Originally, 1.5V x 4 = 6V —-> 1.2V x 5).
Camera has its built-in Flash and it was working though, as I wrote before, I don’t like this kind of
direct flash lighting. So that, I made a Light reflecting adapter to bend the light upward.
Then with a hand held white paper this light was reflected again toward the subject
therefore able to create more natural lighting with soft shadow. (photos below)
(Left: By camera’s built-in Flash. Center: with the reflecting adapter and a paper.
Right: (the same)—- the difference is obvious. (This is what the Photography is)
To have a modification of existing flash system, there could be tens of different approaches,
each having pros and cons. Without a heavy internal modification, put a cover on the existing
flash with light sensor to trigger another flash-light is a viable alternative. —– In fact, you can
test a small reflector like this, Just use a small piece of baking-foil, stacked 45 degree on front of
your camera’s flash. —– If you got a camera, which is no longer in use, why not to try.
There isn’t much mystery in the camera design, if it was designed by a human-being,
why not possible to modified by others. Just do it. It’s a fun. :-)
And it would be a start of ACTIVE creative photography to play with light !

Handmade Flash System (1) — Flash with Umbrella
Among my flash system, this is the one I’ve been using the most.
Most (not exactly all) of the photos of table-top shot kind in this blog such as
cooking samples has been photographed using this flash system.
And some party shot such as Capricorn Party was shot by this as well.
The base of this system is an Agfa 383CS flash-light (but actually it was made by Japanese Nisshin)
which takes SCA300 camera interface adapter (so, I used to use the adapter for Nikon, Canon, Contax
etc etc. for TTL compatible type, AF compatible type etc etc.) though, as the camera evolved so rapidly
and their control system became too complicated, hence, those system became obsolete in mid 80s.
—– still, this flash itself has External Auto as well, and of cause the full out-put manual and minimal
(somewhat 1/20th) for rapid fire. And on top of this, it got additional front flash to give
“Catch-light in Eyes” when used with bounce-light !
The rotating head has rotating diffuser as well which spread the light coverage from 35mm lens to
24mm lens. —– Almost everything what most of the user needs.
(As far as I know, this is the most well thought-out flash, ever made.
And after nearly 30 years use, it is still in full working order = its reliability is remarkable ! )
But, unless the subjects are more than 5m away, to take picture with a straight
flash-light mounted on camera —– is what I don’t do. If a light was placed next to
the eyes, similar to Head-lamp, there will be no shadow on the subject.
It is the most unnatural lighting. —– For the most of the subject I needed to work with,
(think, a portrait kind in an interview situation, or to capture a dining scene in a restaurant) is
about 1~2m distance. Other shot such as whole room, restaurant, shop etc will be covered by
another more powerful flash(s) or even studio type flash-light placed somewhere in the side.
Therefore, to photograph the subject in talking-distance, I modified my flash-light
to take an umbrella reflector.
Thence, I could create a photo, looks more natural 45 degree lighting, top lighting etc
with just a swing of my hand —– it’s mean, to operate the camera by right hand only = (before
camera was fully automatised with Auto-focus, it was a bit of special skill. —- think about, such as
Pentax 6×7 or Hasselbrad in one-hand operation with almost studio quality lighting, without the
cost of assistant. 😀 —– and that was how I nearly monopolized Japanese business here. 😉 )
The modification of the flash-light was just done by a simple cut and put-together
aluminium piece kind of work which you can see from the photos.
—– May be the most peculiar part must be the Umbrella.
This is the umbrella only one in the world = specially hand made by a craftsman who has been
making studio flash umbrella for such as Kishin Shinoyama etc. The craftsman had happened to
have his family business, selling and repairing the umbrella in Roppongi of Tokyo, where many
photo-studio situated. Since the photographer who brought back an umbrella from the west asked
him to repair or even to make the same, he became the only Craftsman catering those needs in Tokyo.
For him, my requirement to make such small (diameter 50cm) umbrella was, of cause first ever
funny request. Nevertheless, I got the one what I wanted = literally pocket size Umbrella. 😀
(You may find 70cm size which is using child umbrella frame) —– (In fact, I’ve experimented to
make small one, such as using only half of collapsible umbrella or toy umbrella etc.)
—– the reason is obvious, if you got to move around with umbrella, it catch or hit anything =
the smaller the better though, if it is too small, it wouldn’t work as a diffuser.
The size has to be the same size of the spread of light from flash in its distance. )
[]
Most of the Umbrella adopter for a small Flash, fix the umbrella facing straight to the flash.
My design aiming the flash from the bottom, hence some light escape from the umbrella still,
the light intensity is only 2 F-stop drop. Considering the diffused ligh covering
almost Fish-eye lens, the efficiency is not too bad at all !
(In fact the escaped light is bounced back from the ceiling, also contribute some good effect 🙂 )
[]
With the age of very advanced DSLR, which got ISO speed even 25,000, it is easy to produce
the photo only with available light and it looks natural of cause. But in the other hand the skill
to manipulate the image, intentionally hide something in the dark, kind is all left to
the after process of PS. Though the trouble is, PS often looks too unnatural.
Resorting natural light still end-up unnatural image is not very funny. 😀
Because of the shadow, we know the significance and the meaning of the Light.

Robot astronaut Kirobo
This is an article from Gizmag —– it looks cute and interesting story.
