W Lens-B

Thanks to the advancement of the technology and the use of the image recognition system etc, alongside the advancement of the optical design x optical plastic = we may find many usable aspherical lens in many devices.

So, I got a plastic lens and I made yet another W lens for my camera. —– using the same idea of 2 cutted half lenses put together.

The effect was more or less the same to W Lens-A but the bokeh is a bit more prominent.

Basically those lenses were designed for omnifocus, yet still a close-up extension ring works well. (omnifocus works only within a limit) 😀

Whether you like them or not I don’t care. I’m quite happy with them because, I feel that the image is much closer to what I’m living with. 😀

LED Macro Light

Such as 110 Instamatic Macro, when the magnification became larger, the focusing become increasingly difficult = simply its became too dark. Flashlight wouldn’t help focusing. —– So, I made a LED Macro Light for Instamatic Macro lens.

In fact, I made many LED Ring Light before and this one is so far the smallest of all.

The first one I made was not satisfactry and I needed to make another. (You may think that the LED has no problem of heat, but the LED’s efficiency to convert the electricity to light is only 40%, its mean, rest of elecricity all goes to the heat = LED is a 60% heat generator. With over current and the over heat, LED detriorate very quick = heat management is the key point of the design to use LED)

Photo left a LED, the left hand side is Kathode (-) why it is big was to disperse the heat. And the photo middle was the LED macro light which I made this time = its (-) side all together soldered to a center brass ring to disperse the heat.

Light distribution seemed OK (photo right). Though, the image of ring light is all ways boring. (Still, we can improvise them = such as to cover the one side LED using black-tape, etc.)

.

Further modification

As I mentioned on the previous post that the 110 instamatic macro lens needs the helicoid focusing —– I did the work.

Photo right showed the finished work together with 60 mm Extension ring = both Rear lens cap and a camera body cap were fixed to the left over can !

To put a focusing helicoid, the barrel (water can) was cut first (Photo left) The internal diameter of the can happen to be 64.5 mm which was about match to a 58 to 62 mm step-down ring = so, it was connected to a 25 to 55, 58 – 58 mount focusing helicoid from China. Then they were connected to the Nikon Z with 58 to NZ reverse adaptor. (Its mean, to use a 58 mm reverse ring, the lens can be connected to any other camera as well)

Here, everything was conveniently happened to match well. —– in this kind of the work, it is always the luck of “Happen to be” works. When you need, you may find coveniently matching component etc or got pretty good idea etc ( —– If it was not on your case, think about = you might be rued to the God in your life. ) 😀

Photo left = Helicoid was shortest 25 mm, Middle = Helicoid was 55 mm, Right = + 60 mm extension ring

With this modification, the size of the subject could vary from 6.5 mm to 9 mm (x5.5 ~ x4) (with extension ring 5 mm – x7) and the focusing became very easy. = I did Nice job.

Cicada ?

I don’t think we can see a cicada in this country —– other than a its tiny cousin called Froghopper. —– still, I never seen such highly decorated costume on them ! = I was very impressed !

The photo left showes the size on millimeter scale = about 6 mm. Note the size of her hind leg that was where her nickname Froghopper came from.

While tidying up the desk I found a small dead insect among the dust. For most of the eyes, this small bit may not have any significant meaning though, I came from the country where the noise of cicada singing fill the air of sommer all the time (even in Tokyo area) I wouldn’t miss “I know you well” —– the insect was not exactry a cicada but a kind of froghopper. Still, they got the typical same shape.

So, the 25 mm 110 Instamatic Camera lens, reverse mounted to the can which can give about x6 magnification = the result wasn’t too bad for a cost nothing junk —– (may be I should give a helicoid focus on top for a ease of focusing.)

.

W 1/2 lens

Here, [W] didn’t mean 2 indivisual lens. = Both of the half cutted lens. Ideally, the soft image should have the nice halo around the sharp core image —– if there was no sharp core image, it was just an obscure bad lens image. = So, how about the one lens was divided into two and the one half makes focused image and the other was making out of focus bokeh on the same one picture ?

From a Kodak (one time use ) Fun camera, the lens panell was cutted-out.

Cut an ordinary lens to optically functioning 2 separate half was not very easy. So, I did it with disposable (one time use) camera’s lens. = Cut it into half (Photo left) and mounted the one half to normal position and the other half to out of focus position (Photo middle). —– (Then I noticed that the lens I experimented makes rather nasty ring bokeh when it was out of focus —– I needed to search more.)

Photo Left was taken by the original single lens. Photo right was done by the W lens.

This W lens is efectively a w-focus lens. I experimented many w-focus image done by double exposure, or lens shift. But here I took a drastic approach to use cutted two halves lenses. —– I think, it wasn’t too bad idea. The work I took was rather awkward though on the end it was well rewarded. ( = I think —– anyhow, I got prenty one time use camera junk to try again and again 😀 )

.

Stabilize the Camera — Head Pod

This is yet another trick to stabilise the camera after chest pod —– or analog aproach to stabilise the camera.

Photo left is for right eye use, Photo right is for left eye use (Pod was reversed)

If you ever try to take picture of the flower in the very close-up way, without a tripod, you may well experienced an awkward trouble to hold or suspend the camera in the exact position. Image stabiliser may stop the shake of the camera in certain extent = say 0.1 mm shake or vibration though, no mechanism would help to stop your camera drifting — say 1 or 2 mm above the flower. Worse still, if you take picture while using LCD monitor, holding the camera in the air, you can’t make your hand like a solid wood. While your hand may drifting or sway, your head may not shake like your hands = so, why not stabilise the camera with your head. As a matter of fact, when you attach a flash light on the shoe, your fore head may resting on the back of the flash light, so the camera is much more stable. —– so, why not make something to rest on your fore head to stabilise the camera. = The prototype I made (in fact more than 30 years ago) works very well (but only on horizontal way and right eye use — for left eye use, the pod has to be reversed like a photo above right). (The metal piece itself was a simple cut out from a left over of a window frame, inserted into a plastic flash adaptor)

O-M-G — Apple

OMG — the seeds started to germinate inside of fruit !

This photo was taken by a homemade lens called Yashica Macro. https://yoshizen.wordpress.com/2016/05/14/yashica-kyocera-macro-2/

This apple must be rather old — still, not started to rotten = must be sprayed with the strong chemical to make a long shelf-life. Still, the fruit itself has its own internal clock and timed for the moment to come-out.

Of course, the apple was not created to be eaten by a man let alone by Adam. In nature, the fruits will be fallen to the ground and the seeds germinates from its rotten but nutrition rich seeds bed. —– we are only intercepting their process and robbing their opportunity.

If you are “Pro-life” activist, you may plant this seed to a pot to grow an Apple tree —– but sorry Miss Apple, I’m not such tender person (in fact, I had too much trouble before to have too many such pots of plant) I’ll just throw you into a bin. (I’ve been killing too many lives, vegetables, fruits etc etc thrown into my cooking pan etc etc = too late to pretend to become tender hearted hypocrite.)

Our vision — Photo image

This is a part of the previous post —– as I found it got very important point in the aspect of Zen (See — feel — think — what is real — truth) not only in Photography.

Rather fragile looking Scabious —– the lens showed peculiar depth of field image, and the size of back bokeh is gorgeous.

(But have you ever seen such bokeh image in nature ? —– they exists only in the photographic image = they are not real, neither your eyes are telling the truth —– So, how can you tell that the photography IS the faithful copy of the real, without knowing your own eyes could not tell what is real.) 😀

(For example, we are not seeing square building, since we got fish-eye vision as our eyes are round ball, so that, our brain is reconstructing the image following the stereotype that the building is straight = therefore, the photo of the building has to be square ! —– So, how can you tell that the photo of the building is faithful copy of the real building, = you see what I mean.)

Fuzzy Macro for flower

They are the photos made by a homemade lens called NZ-B = It’s a very peculiar lens, = utterly fuzzy though in the certain condition, strangely it shows quite sharp image.

This one may seemed to be taken by any ordinary macro lens though, with a much of amazement, even an annoyance, it was done by the same NZ-B lens on Nikon Z7, AV mode.

In certain extent, this lens would work just like a fuzzy 40 mm F2 lens.

Still, under close look, the image has quite a detail.

Don’t aske me why I didn’t come here a week ago. —– It’s happened as it happened. (That is what the life is.)

When it was far fore-focused, the image became like this = I like this. I think, no other lens ever made the image like this bokeh. And the bokeh image like this only exists photographically = never in the real world.

Hind-focused (photo left) = lens was sunk beyond the infinity position / Focused (middle) / Fore-focused (photo right) = lens helicoid was fully extended = like for a close-up shot.

(Only one exception, the photo above left was taken by the Pentax 110 Auto 24 mm lens)

Quite exotic flower — I have no idea who she is.

Very impressive though, I never seen her anywhere else. — (Is it a kind of Thunbergia ?)

But this one is very common, yet I love this painting like image. (It seemed that the loss of tonal dynamic range was not caused by the softness of the lens but by the brightness adjustment of Picasa and a very bright color = red.)

Still, the same lens can produce prosaically clean photography-like image as well.

The photographer is believing that they are the user of “Photography” though, in reality, the provider of the Photography (= camera maker, photo journalism etc) is using photographer to keep and run the industry and the idea. So that, “Photographer” was made to believe a type of photography which was provided and such stereotypical style “IS” only the photography.

= The belief IS “Photography is to make a faithful copy of the subject” while blindly believing that his own eyes is seeing the true face of the subject. —– In reality, no such certainty ever existed.

And rather fragile looking Scabious —– the lens showed peculiar DOF and the size of back bokeh is gorgeous.

(But have you ever seen such bokeh image in nature ? —– they exists only in the photographic image = they are not real neither your eyes are telling the truth —– So, how can you tell that the photography IS the faithful copy of the real, without knowing your own eyes could not tell what is real.) 😀

(For example, we are not seeing square building, since we got fisheye vision as our eyes are round ball, so that, our brain is reconstructing the image following the stereotype that the building is straight = therefore, the picture of the building has to be square ! —– You see what I mean.)

——- ! ? ? ?

Here a kind of anemone ? —– anyway, the matter is the image. (If you can make a soft image like this using PS I would like to see it !)

I’m not familiar with this flower —– pretty impressive, and it looks even cannivorous. I wouldn’t be surprised if I see the dead bodies of insects laying inside, half digested. (Do you know what IS the truth.)

And suddenly here rather humble looking flower = the color of blue jeans, Indigo came from this plant. (or larger sister of her)

(If I could stop down, the image could have deeper depth of field though this lens has no iris = always fully open F2. But considering the condition as it was fully open F2, the quality of close focused image was amazingly high !)

Then, funny looking chap = the nuts of ceder tree, not a Pokemon still, he looks very very happy today !

The world seems to be pretty peaceful.

Retrofocus

Y-Mac + Div’lens

Behind the lots of experimental / homemade lenses, I got mountain of diverging lens which came from mountain of discarded lenses. —– Converging lens can be easily used as an image projecting lens in many occasions though, not many use of the diverging lens. I did used it to make Wide-angle Pinhole and for Two element homemade lens which was to extend the focal length of the disposable (one time use) camera lens for 35 mm SLR camera.

The diverging lens was simplly stack to the front of the Yashica macro lens (focus was made by its zooming helicoid) and the size of the image was depend on the distance between the Yashica lens and the diverging lens = if it was made adjustable it will become a zoom lens.

Scavenged homemade lens / Yashica Macro is quite good lens though, it got rather limited use only for the macro shot. — Why macro ? Because its focal length was too short to be used on the 35 mm SLR even on the mirrorless camera = When such lens was mounted on the full-size camera, it was same to the lens was focused to very close. = Close-up or Macro shot.

But the focal length of the lens can be extended by the diverging lens. = So, I tried it with a diverging lens which came from a Nikon Zoom lens = It worked well !

Somewhat similar to the situation of “Twisted lens” we are discovering the “inconvenient truth” of the optics. They may not be a residents of the holly land. (I’m talking about the optical effect — utilising its effect while making precise lens-shifting mechanism etc and make usable / reliable products is far beyond the ordinary man’s capability.)
