110 Pentax 24mm Lens test

Considering the image size of the 110 Instamatic was 17x13mm, so that a lens for that camera could able to perform like this on the 35mm full size was rather amazing.  (In fact, inevitable corner fall off is creating even nicer atmosphere)

Such a small lens on a small mirrorless camera is very handy though, to be honest, such convenience makes rather casual attitude of the shooting, and often produce unsharp / blurred image.  I often create blurred image though, it was “when I intended” —– otherwise, it was nothing but a failure.  (another trouble was, that against such small lens, the shutter shock of A7R is comparatively big = tend to make blurred image) 

Such pictures may not have any artistic value still, if we could read the name etc. the details on the goods, there might be a bit more interest.

I wouldn’t pretend any meaning on those images, —– just an atmosphere.

And may be a kind of the test of the lens character.

This photo showed rather interesting phenomenon.  The center is not as sharp as its surroundings = the lens may be showing the curvature of the image.  —– But, I don’t believe such as like the Pentax made a lens having an image curvature.   This got to be what they intended =  intended what = to compensate the curvature of the film. 

I think, other than the Pentax design team, not many people has tested this lens on the camera other than the dedicated  Pentax 110 Auto  body.   Naturally,  the test on the 110 Auto was done by an Instamatic Caset film = which may have inherited curvature of the film though it has been compensated by the lens’ own image curvature.   It’s mean, nobody was able to notice the image curvature of this lens before.  (other than the very Pentax design team) —– How interesting.   😀



Rather Blured image

Ultimately, on the photography, it is irrelevant to know the name of the camera.  Since, the matter is its end result = image.  (Yet still, if you want to know, those photos here were taken by the Kodak Vest Pocket Camera lens on the Sony A7R body.) 

(Incidentally, do you noticed that the guys behind the gate of the Downing street holding a machine-gun.) —– now you must be convinced, that they looks like holding one, —– don’t they ?   In deed they really looks like so.  (you know it’s all in your mind —– you are only seeing my dubious picture)   😀

So, we are seeing what we want to see.



Following the previous post, this is the even more enigmatic piece.   In fact, I just lost a word and got my jaw dropped.       I’m not sure, whether I can call it a dance —– or just an expression happen to be on the body ?

(The viz looks quite dark and mysterious, even nightmarish. —– and that’s I like) The Art in this level would negate all the question such as where it came from or even who made this.  Though, the harsh reality is, we may not able to see the same, after some years or decade as the body of the performer will be lost.   Without the body, its controlled movement and its moment, this art couldn’t exist. —– should we feel sad ?  —– the even harsher reality is, the memory, and its container = brain will be also rotten in the same time.    Who said art is long ? —– (Youtube viz may last longer —– yet it’s horrifying to image, after all the living things extinct, still those video data will remain as the electronic form like a fossil stone. 

Those two above were more like commercial dancing still showing some relation to the first piece.      (They are quite beautiful.)

Morning Sky on Oct’ 2018


( 13-10-2018   / 06:04 —– by Zeiss Distagon 18mm F3.5 for Nikon on Nikon D850)

It seems this was the only second morning red sky in this autumn.  Whether it was the matter of the angle of the Sun or the clarity of the Air, we don’t have red sky in summer.

Wide Fun

(The same sky by Omnifocus Fun lens on Sony A7R —– / 06:05)


( 05:58 —– by the Kodak Vest Pocket camera lens on Sony A7R)

Screen shot by Soft lens (2)

Mag COPY(1)_DSC0028

I found this pretty image in the net.  The original was much sharper, rather normal picture.  When I took screen copy using my homemade Mag lens, in order to avoid a moire, I gave a bit of off-focus.  It was a character of the Mag Lens, when it was off focused, the image suddenly increases the aberration thus, the image become nice soft picture.

Mag COPY(2)_DSC0024

This image was not as much as off focused like the first picture. (Just enough not to see the screen pixel, hence neither moire)

Mag COPY(3)_DSC0027

Then give a bit more off-focus.  —– Isn’t this picture looks more sexy ?  (Shame, I was not the photographer to see the lotus flower in the first place)

I think, now you were convinced to appreciate soft image !


Mug shot (2)


Yet another collection of Mag lens images taken around the Oxford street, London.


Sony A7R’s AWB tend to give brownish adjustment when it has too much blue sky for alien lens.



Strangely this lens is pretty good to create 19thC townscape paintings like image.  May be Sony’s brownish AWB was contributing to this tendency too.







Only a trouble of this Mag lens is, its effect is sometime unpredictable.  😀


Vest Pocket image on the 6×7 camera

Vest'P6x7(1)-A09A8379In the previous post, you might have seen the Vest Pocket lens’ image captured by a 35mm full size digital camera.  Though, the original size of the Vest Pocket camera was 6×9 (43mm x 65mm exact) —– so that, the image only on the cropped center wouldn’t show the full character of this 100 years old lens. —– (Strangely to say, don’t you agree this picture above looks like 100 years, even 200 years old painting ?)  

—– The fact, you must be noted is, 100 years ago then, the user of Vest Pocket camera seeing their picture contact printed on 6×9, card size B/W print.  Today’s reader of this blog can see the picture’s detail / sharpness easily enlarged, though there was no such luxury in old days = people just accept the picture made by the camera (with no focus adjustment).  As long as the picture showed the face looks like your boy, it was a good picture ! 

A funny story was,— there was a Photo-club in Japan,  namely “Vest Pocket camera appreciation club” (Ves-tan Club”/ べス単クラブ — Ves-tan stands, Single lens Vest Pocket ) of which the photo enthusiasts of the photo image made by the Vest Pocket camera was associated together.  And among the members, there was a special practice = use the camera while lens’ front hood which restricts the aperture smaller was removed (— See the previous post =  Lens was originally F6.6 but with the front hood makes it to F11). So, they appreciated the images with soft bokeh by the spherical aberration, the most.  In today’s standard, they might be branded “Otaku”  (It was almost like a religion, same to prefer the images made by the Canon or Leica lens than the Nikon, saying that the Canon shows the atmosphere / or taste (aji / 味) more, but the Nikon lens pick-up just clinical flaw of the skin.  —– mind you, this was the story of 40, 50 years ago.   😀 )  

Vest'P6x7(2)--004I mounted the lens on the Pentax 6×7 body using a camera’s body cap and tested its image character.  (You may say, 6×7 is not 6×9 though, don’t be too fanatic = it wouldn’t kill you anyway) 


(In order to mount the Lens unit to the body cap, an aluminium ring was cut out.  Because the lens has to be very close to the camera body, there was no space to put a focusing mechanism.  So that, the close focused image was made by adding an extension ring. )

Vest'P6x7(4)-A09A8359So, I took some photos on the 15 years old,  Fuji, Provia  ISO400 film — but exposed as ISO160 as I anticipated the film’s loss of sensitivity in time. — (Since, the lens was set to maximum F-aperture (F6.6) the image was pretty fuzzy on the 6×7 Pentax view finder too = rather difficult to see the definitive image.)



(Since the 100 years old single grass lens has no coating, image has a lot of halation as well.)




(Fuzzyness was created by not only its out of focus bokeh but by its aberration too.)



(In here you can see a lot of bokeh by the spherical aberration.= unlike the intentionally created bokeh of Helicoid Lens (A) or (B) kind, Vest Pocket lens’ fuzzyness looks more natural.)


So the painterly effect of this Vest Pocket lens looks rather subtle and looks natural. And the image has more atmosphere which gives more depth to the image too.  A depth of its image was induced by the emotional resonence (something like = I’ve seen this long time ago), not from the detailed data which will talk to the intellectual brain —– in fact, too much data in the image distract an emotional response, exactly like a noise in the music.

(Which the members of the “Ves-tan Club” most appreciated.)


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.

Short walkB(5)-DSC09267

Short walkB(9)-DSC09283

Short walkB(6)-DSC09279

Short walkB(7)-2018

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(10)-DSC09294

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.



Deeper into the Zen

Some of you, the keen followers might be wondering what this man is  talking about ?   And what would it to do with Zen ?

—– The fundamental question is, “If the Zen is to deal with the life in the absolutely empty mind =  in Mushin, (completely dispassionate, almost like a machine) —– Hey stop joking, which part of the brain is actuary handling it ? ”  (If somewhere the brain IS handling = with the intention to handle it, IS not Mushin but just not aware what he is doing, it’s a fraud ! )

How I came to here, you may find how our condition of the Guts (and the chemicals of its bacteria, parasites) influencing our “Feeling = Heart = Mind = ultimately the way of thinking”   We are not really in control. (Since this blog IS the live description of the DIY Zen research, I need to see the mechanism what makes the Zen as Zen —– in fact what IS so-called Zen ? = if any at all ?)

Now you must be convinced, that the so-called Zen teaching in the town IS fraud. Zen couldn’t be learned or taught, while saying Zen.  As long as the notion of Zen in mind, even if it was hidden in the deepest unconsciousness.  It IS not Zen.  I’ll show you “The legend = the Archer who try to reach Zen while learning Archery in Japan” in the next post. (If you like to start ahead, find a book and read it before hand = Zen in the Art of Archery : by Eugen Herrigel —– It’s a small book = 100 pages or so in a Penguin books)


PS : I’ll explain you, my utterly strange Lens Making Game.  Do you think is there any complicated theory or creative notion ? —– Non at all.  It was the same process of the cutting a lemon.   In other word, a kind of work of Just Do It with a material I found then —– Imagine, do you think would it be any sophisticated philosophy or scientific theory behind ? = far from it, cutting minute depth of metal barrel to match the focus = IS the ZEN.  (I don’t have a skin thick enough to have a pretense to show-off “Copy the mantra” kind)   😀
