Short Walk (B)

Short walkB(8)-DSC09273

Short walkB(1)-DSC09243

Those photos were another product of the same Short Walk (A), hence using the same homemade lenses Helicoid (A) and (B) on the Sony A7R.     While walking through the park, finding which flower is really a chance encounter, and how to capture it, while seeing the character of the optics and the shape of the flower, how to compose it, in which angle and the distance IS what all about the Photography.  In certain extent, it is a game or the match between the two personalities.  In Zen Buddhist term, we are living on the moment to moment life.   And to deal with the Person (subject just encountered) as if there is nothing else exists and nothing else to do is, so-called Mindfulness, and in this mind-set, there is no Ego.   So, this situation is a proof of the No-self or Anatman.   Yet still, in other stance, to see a subject as a subject might be seen as yet another Ego, therefore not aim the subject but to see everything as the everything may be a right view.   Though, in practice, the image of an ultra-wide angle lens clicked random is just a mess —– so, the question is, whether the Zen needs a nice answer ?    Or such answer itself is not Zen ? ? ?  —– Good question.   What a nice day ! —– Ha ha ha,  😀  

Short walkB(2)-DSC09268

Short walkB(3)--2018

Helicoid (A) lens happen to have an Iris, so that, by the depth of field control, flower showed a bit more details, still, take the image of Helicoid (B) (photo right) is a matter of the taste.

Short walkB(4)-2018

Both (A) and (B) lenses, its center of close-up images are amazingly good.

Those two pictures were given a shake when the shutter was opened. (Don’t ask me what for — it’s only for a fun)

Short walkB(11)-DSC09293

I realized that I don’t have many photos of the Blue Bell.  May be their flower is too common, yet only in a short period.  Still, why it makes the difference to the Cherry ? —– M m m ?  —– I might have an unconscious notion, that the Cherry is the Japanese but the Blue Bell is English.   But why ? ? ? —– May be because, I didn’t grow up with Blue Bell but with Cherry.   As the photography is a way of the Self expression, it became a kind of a biography.

Short Walk (A)

Short walkA(1A)-DSC09254

In deed, I haven’t have done a photo-walk a while. —– without a reason = IS a problem = just getting lazy.   So, bashing myself and went out with a camera and two lenses. (still, all in one pocket = that’s a beauty of the small homemade lenses. = Helicoid (A) and (B) lenses with Sony A7R)

You may wonder what was a point to have those two lenses.   Ha ha ha, you are right.  Both of them are equally fuzzy lenses.  The differences were, —– if the fuzzy surrounding has Coma bokeh, it was the (A) lens.  And if it was with Astigmatism bokeh, it was the (B) lens.   Both for the sake of painterly effect which I like very much.

Cherry Cherry – 2018

Cherry cherry(1)-DSC09146

Since I put the photo of the first cherry, it’s already 3 weeks past.  They are still in full bloom though, the flowers started falling. The end of Somei-yoshino season.   (Then Multi petals cherry is coming.)

Cherry cherry(2)-DSC09140

So, this year’s Cherry pictures were made by “Helicoid-B” lens.  (One of the worst reputed lens ! = therefore in these days I’ve been using the most.   😀 )

Cherry cherry(3)-DSC09147

Without me shake even a single finger, the picture became almost trembled. ( = The technique to produce the paintary effect in the most economical way !     😀 )

Cherry cherry(xx)-026

Cherry cherry(7)-DSC09150

(Only the problem was that the image in the finder was too fuzzy to see the focus.)

Cherry cherry(5)-DSC09166

So, those two (three) photos were taken by a kind of normal lens = Tamron SP 500 mm Mirror lens. —— Somebody teased me saying “Can’t you take normal picture ?” “I leave that kind of business to the Phone camera user, otherwise no point for me to use bulky interchangeable lens camera”   😀

Cherry cherry(6)-022

Though, the Tamron gave me too pale color.  (May be I need to use Photoshop kind though, that’s what I hate most.)

What ? — OMG, it’s Cherry flower

Cherry-18(1)-DSC09083

On the street, I found a dropped Cherry flower.   —– ?    What ?   —– I looked up, OMG it was a cherry tree started to open the flowers.   Only few days ago, there was nothing.  It’s suddenly happened.  I picked up a dropped flower and a bud to bring back.

Cherry-18(2)-021

I put the flowers on the water in a lens cap.  And took pictures.  (After a while, a bud opened as well) —– It was a kind of my habit in these days, which was to make the photos for comparison = the photo left above was taken by Sony 30 mm F3.5 Macro and the right was by Helicoid-B lens.

Cherry-18(3)-5-001

So, this year’s first Somei-yoshino flowers were put next to the kitchen tap = In fact, this IS my photo studio.  (All the “Studio shot” in my Blog were taken in this “Studio” !    Another funny fact was — that all those homemade lenses were made in this kitchen work shop, and almost all of my sculptures were also produced in here.)  

It’s very simple, if we need to make, make it, or just do it.   There may not need to have any good-cause or theory or facility kind.  So, if you have a knife, you can cut.  With the same knife, you can cook as well.  If you can’t, you were just clinging an excuse of not to do or even worse you might be waiting somebody to push your back.   😀     (By the way, this is in deed the way of Zen = Zen need no cause or reason to do.  In fact Zen is to eliminate anything that kind.  Therefore Mushin (Mind of No mind) still, even a mind to think No-mind shouldn’t be there, = hence “Everyday’s Mind” (Heijo-shin 平常心). That’s why to able to be in the Everyday’s mind which is nothing special / peculiar  (is so ubiquitous as a dog shit) IS the Enlightenment.

Canberwell Cherry by Other Lenses

Hel-B

You may think, the camera was rotated but this swirly bokeh was the lens’ own aberration.

Hel-B

Those two were by Helicoid-B lens 

G9

G9

And those two were by G9 lens

G10

G10

Those photos above were by G10 lens

SZ

What I don’t like about this camera was, its AWB (White Balance) changes frame to frame.

SZ

And those two were by SZ lens

—– The hardest part in those photography was, to sort the photos without mix-up, not mention the trouble to capture them while holding the camera high above the head and shoot by guess-work. (You know, the Photography is a hard work)   😀

Camberwell Cherry by NZ Lens

NZ

NZWhile passing through by bus, I noticed that a Cherry tree in a corner of the Green was in full bloom.  So, I went back there with my camera together with some homemade lenses. 

NZ

(In this photo the red cast seemed to be created by the camera’s image processor — may be non genuine lens may not work well with this camera (Sony A7R)

Cherry itself seemed to be a primitive wild cherry, we called Yama-zakura (Mountain Cherry) in Japan, not the well cultivated Kan-zakura (Winter Cherry), nevertheless Cherry flower is the Cherry flower. (May be from the mountain standard, the climate in the town was warm enough to open their flowers.)

Camber-Cherry(2)-002

(The photo above left was the other tree nearby — this one seems a Plum flower)

The photos in here were taken by the lens called (or, I named) NZ lens.  It was a Nikon Zoom lens which I utilized its front element, and made it as an individual lens. (Works as a 90 mm F1.6 and able to focus down to 45 cm)  Its macro quality was not too bad though, it got a strong aberration and together with its “Fully open” F1.6 aperture (Think, 90 mm F1.6 is pretty big), it’s creates “Fantastic” fuzzy images like those top photos.  They were shot while using 10 mm extension ring.  And this fuzziness IS very unusual = it looks like a halo in the highlight which spread around still, the details and the contrast in highlight was maintained. = I never seen the image like this.   (If you agree with it.  😀 )

Instamatic-304 & its Lens

Insta(1)-304-A09A8033

This Instamatic Camera has been sitting in my junk box rather long time = Because  1) I’m not very keen to disassemble Instamatic as I had hard time to deal with very awkward mechanism (It seemed, Kodak designer was not very smart) on the previous experience.  2) I’ve got too many similar kind of fuzzy lenses already. —– The lens on this camera has no focus adjustment, still it was made long before the Japanese one-time use camera by which omuni-focus lens became common = could mean, either very interesting omuni-focus lens or mediocre lens which rely on the small F-aperture (— when people goes out, it will be a fine day and the camera’s EE control will give a smaller aperture with deep depth of field).—– But, I’m not going to use their EE control = I’ll need to have a focus adjustment. = may need to use a not very smooth focus helicoid recently got from Ebay. —– ?

Anyhow, I disassembled the camera.  Since the camera was using only few screws to build and many parts / panels were glued down = as I anticipated, it was a very awkward hard work. (I wouldn’t recommend you to do this.   😀  )

Insta(2)-304

Then I remembered,”If I need a helicoid”, I got an empty helicoid of the Canon FD lens, of which I took the lens out. (Photo left) From that empty shell, I further removed the FD mount part and the front cosmetic part. (Photo middle)

And put the lens which I’ve taken from the Instamatic-304 camera (Kodar 41mm F8 Lens) into the Canon helicoid on Sony A7R  (Photo right)

The test images of this lens were like those —–

Insta(3)-305

Then, I made a fatal mistake.  After final assembly, in order to clean the lens, ( — I thought, that the white smear on the lens was caused by the plastic putty) so, I used the alcohol to clean the lens though, as this old plastic lens was not made by the today’s optical plastic but by a primitive stirole kind of plastic = the alcohol destroy the lens surface = and the image became like those.

Insta(4)-306

M m m, —– even to a man who fancy the fuzzy images, these were gone too far, not funny at all.

On top of the snowy weather and CH brake down, life is hard and complicated.   Not funny at all.   😀

Lens Comparison (2)

Z-18mmThis photo — by the Zeiss 18mm F3.5 on Nikon D850 / ISO 800, 250th Sec —– (All the photos in this post were cropped only in its hight, and the width were kept as its original to show the relative angle of view of each lens —– for example, after the widest 18mm, next wide image was shown here by the Fun lens, which was originally an one-time use panorama camera and the viewing angle was the 35mm equivalent of 27mm lens.)

Seeing the same old sky, I took the picture of the same, with many different lenses —– and made more or less the same images.  😀

Comp(2)-A09A8019

Still, they are only a half of my homemade lens stocks.  (It’s annoyed myself a bit) 😀

Helic-BThe first of this operation was, the Helicoid (B) with a setting of ISO100, 650th Sec —– since this lens has the brightness about fully open F2.2,and 2.2 only = no iris = needed to use lower ISO.

FunBy the so-called Fun Lens / ISO 100, 15th

Helic-ABy the Helicoid (A) / ISO 100, 320th

G9By the G9 lens / ISO 100, 1250th

MagBy the Mag lens / ISO 50, 650th

Son-30mmBy the Sony 30mm F3.5 / ISO 50, 500th —– I can not stop thinking, what this “sharper” image can give us, more than the other fuzzy images ?

SZ-55mmBy the Sony/Zeiss 55mm F1.8 / ISO 50, 2000th (It seems something wrong with this lens’ focus = even with manual setting, the lens moves away when the shutter was pressed = may be that’s why it was offered so cheap. (and lots of them in the Ebay)   😀 

Koda-Red100 years old Kodak lens (equivalent of 175mm F10 / ISO 400, 500th —– as a 175mm telephoto lens, the image was quite good, especially considering that the lens consists only symmetric 2 glasses, that’s all ! )

Koda-FunBy the Koda-Fun lens / ISO 50, 4000th

SZoomBy the SZ lens / ISO 50, 1250th

OmuniBy the so-called Omuni (focus)lens / ISO 50, 1250th

More or less the same fuzzy images though, still got each character.  It’s not too bad to play with those lenses.  (Anyhow, they didn’t cost me much — still gave me a lots of fun)

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.)

Helicoid-B(2)-A09A7721

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.   😀 )

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.

birthday party(12)-002

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 !
