Macro shots (2)

On this post, all the shots were made by Pentax 110 Auto 24 mm lens on Sony A7R4. And looks like macro shots were the heavily cloped small part of the original photo’s part enlargement —– can you find where it’s came from ?

So, it is clear, a lens I bought for £5 from a junk box, Pentax 110 Auto 24 mm lens has the quality of the (almost) top lens, and the 60MP image sensor of Sony A7R4 can capture (almost) whole amount of those visual information there. Therefore, a wide angle casual shot of a 24 mm lens was in fact, holding the details of the macro level too.

Pretty Good isn’t it ! So, I like this Pentax 110 Auto lens on the Sony A7R4 camera always in my pocket. 😀

Macro shot ?

Z55 – A7R4

Once before I found a trouble of manual focusing in the Sony camera. So, I was testing Zeiss 55mm lens on A7R4 body with Focus peaking and the Focus magnifire. —— This time both function worked well = AND I amazed by its fine details of the captured image. = The silk flower was 100 cm away yet the enlarged image showed a real close-up = macro quality.

Z55 – A7R4

I wonder IF this fine quality came from the quality of the Zeiss Sonner FE 1.8/55 ZA lens or the camera’s 60MP image sensor ?

AI Nikkor 50 – A7R4

For comparison, this one was AI Nikkor 50 mm F1.2 (at F1.2 / 100 cm) on A7R4 (this 50 years old 50 mm lens seems to be a bit softer than Zeiss 55 mm —– But, F1.8 lens got to be sharper than F1.2 !)

AI N 50 – N Z7

Then, how about the AI Nikkor 50 mm F1.2 lens on Nikon Z7 ? It’s haed to tell if a bit softer image was caused by a larger F aperture (F1.2 instead of F1.8) or a bit fewer pixel number (46MP instead of 62MP).

P110-24 – A7R4

On the same setting, I tested it with the remotest possible lens = Pentax 110 Auto 24mm F2.8 lens === 24 mm lens image was far smaller than the 55 mm lens. Still, the enlarged image showed quite a fine detail !

It’s suggests that as long as the lens was seriously designed good lens, its can produces very fine details = IF the resulting image was not very fine, it was because, the camera / image sensor / image processer was not good enough.

P110 – NZ7

This is the comparison = The same Pentax 110 lens was mounted on the Nikon Z7 body through a homemade NEX – NZ adapter. —– Even though the same optical image was projected, the smaller sensor seemed to produces a bit rougher image.

Godo – A7R4

So, see the image of the lens which was not seriousely designed or made = homemade Godo-lens.

NZ-B – N-Z7

Then, how about the image made by yet another fine camera Nikon Z7. —– But (you believe it or not) I don’t have an authentic lens for this Z7. (I’ve been empoverished by its XQD memory (made by Sony), expensive spare battery etc —– I can not afford to buy their lens.)

So, the Z7 camera was tested with another homemade lens, NZ-B lens which showed very fine undefined image !

Early Magnolia 2020

In this post, the photos were taken by a homemade lens Godo Lens, except no.4.

Those photos were taken by Tamron SP 90mm Macro on Nikon Z7.

I featured this flower twice (?) before using another fuzzy lenses. But, it seems the people takes the flower branch home there is no branch left on the lower part of the tree, and made me very difficult to take picture. (So, I needed to resort with something special measure. 😀 )

Those following five pictures were taken by the other homemade lens “Pla-B” Lens” —– though, with the bad weather I trid three times to get a kind of results. 😀

.

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 😀 )

Screen shot by Soft lens (2)

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.

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

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 !

Oleander

This is a tree flower which I have deep attachment, hence I want to see more here = though, strangely she was not planted often.  Probably because people afraid of the poison of this plant.   In deed, if you feed the handful leaves to the animal (cow or goat kind) the animal would die easily = strange contradiction is, its poison (Oleandrin) has very similar effect to the poison of Foxglove (Digitalis / Digitoxin = Very strong stimulant and or poison to the heart) —– yet you can see the Foxglove everywhere even though Foxglove can kill you too.
The reason why I feel such attachment to this flower was, she was associated with some poets who I respect, — and its poisonous nature.    When I was small, my hero was the Ninja or humanoid Robot, not a Superman kind of American comic fantasy.  So, we kids practiced how to make a rope to climb a wall or the formula to make a poison.  (still, I never heard of any accident with those poisons = Japanese got necessary knowledges —– idiot can’t be a Ninja = we kids wanted to master the real skill, not dreaming in a silly fantasy to fly a sky.)

Very remarkable fact of this plant, Nerium Oleander (夾竹桃、キョウチクトウ）is, that this plant has the will and the ability to survive while eliminating other plant with its poison.  Oleander was the plant first revived and flowered on the literally scorched ground of the Hiroshima, after that atomic bomb.   Hence, she was named and honoured as the Flower of the Hiroshima. —– (Hidden message here might not be a flowering peace but a kept poison / we never forget.)

(Those photos were taken by a homemade lens nicknamed “koda-fun lens” with or without extension ring.)
.

Judas Tree

If you are familiar with a flower of Sweet Pea kind, you might noticed that this is the same group.  Yes, this plant belongs to the group, used to be called Leguminosae.  Yes, Legume = Beans.   And among the Leguminosae, she must be having the funniest story. 

This tree said to be originated from middle east, Judea country, hence its name.  But the other story was that, this is the tree of which Juda of Iscariot hanged himself, hence it was named so.  Yet, others say, because the tree’s seed pod dangling from the tree trunk, which resembling a hanging body, hence the name.  —– In that case, when the body of Juda was dangled from the tree, people found the similarity ?   Waite a moment, the seed pod of the tree has been dangling from the tree even before the human being inhabited the area, let alone Juda himself. —– M m m ! ?   Which came first ?     

Even more funnier story was that this tree was registered by the Israel Government as a protected species.   It seems, their Government was anxious to keep enough number of tree for their population, when they need.  

What a poor tree.   Isn’t there anything better to hang ? 

.

Winter Cherry (again !)

OMG, —– when I walked close by, I noticed that, that Cherry is flowering again. —– Since she is flowering every winter, it shouldn’t be any surprise though, when actually face it, still it was a OMG.

Though this time all the flowers are rather high on the branches.  I went back there with “Tele-photo Pinhole” = simply it was the DD Pinhole further extended by the extension rings which made it to 105mm Tele-photo.  (If it was a lens, extension ring will work as a close-up device but for a pinhole, it only makes the effective focal length longer. — in fact, as it will make the image larger, it would have a close-up effect as well though, pinhole has no focus at all, in any “focal length”, if you close to the subject, you will get larger image any way.)  So, what so ever the theory, Pinhole image is Pinhole like image.  Too fuzzy.  Still  if anybody want to see more decent sharper images of the same flowers, I got many many other shot. = please go back to them.   😀

(On the photos above, left and middle were the same flower though, the middle photo was by the Mag lens (and heavily cropped)

I may need to come back with other kind of lenses.  😀

Incidentally, soon after I wrote London weather was mild, suddenly it became cold.  And, this is my first frosty photo of this season. (by the Mag lens)

So, anybody in the cold, Please survive well.

Sow Bread (Cyclamen) — (Secondly Photo)

(Top photo was in fact a screen shot of the second photo. — Second =

original photo was taken by a homemade Mag Lens and the

screen shot was done by even fuzzier  Gaudy Lens)   😀

Sow Bread (Cyclamen) was introduced to the Japan about 150

years ago.  Botanist then, Saburo Okubo named it as a direct

translation of the English name Saw Bread to  Buta-no-Manju !

(How beautiful ! ! !)

Most of us think, Cyclamen as a potted flower associated with

Christmas. — As a matter of fact, they are the best-selling plant 

in the winter.   So that, to find its flowers in a shady ground of a

public park was a rather surprise to me. (I have no knowledge or 

a proper reference book to distinguish whether this one was a

wild one or just humble but a tough type for an outside garden.)

.

Biggest selling plant mean, it has a very competitive big market

= how to attract the customer, so to find a good sale’s point is a

serious business.  So that, adding a nice smell to the normally

smell-less Cyclamen having a fierce battle. —– On the end a

Japanese scientist has succeeded to develop a nice smelled

variety by manipulating / tampering its chromosome.  =

Made a cross bleed between C.persicum (2n=48) and the

C.pupurascens (2n=34) with scent, to (2n=41) then by the 

use of  Colchicine alkaloid from Saffron, made it to (2n=82). 

(And further process by exposing to Ion-beam to change its

DNA to create nice color with nice smell.)

The whole process sound very complicated and awful. 

Somebody, a kind of  “Activists” may start a fuss, still others may

say it was not actually tampered the Gene but only the change of its

container (Chromosome) which technique has been used to creates

many Seedless fruits such as  the seedless grape, water melon etc.

(When the number of chromosome set was changed to x2, x3 …

such irregularity obstructs the normal development of the seeds

= hence seedless fruits.) 

Although, the plant can produce the fruits, its plant was fertile =

even a cross-pollination couldn’t produce next generation = no

possibility of its spread of an abnormality = safe to the Nature.

—– ?  is it ?        

(As a matter of the fact, our Nature has been bombarded by the

cosmic ray, nuclear particles etc. which is causing the damage /

change of the Gene.

(Which may have contributed to the evolution of many species.)

—– Even on the worst analogy, an Atomic Bomb on Hiroshima,

must be caused millions of genetic mutations if not just burnt to

the death, didn’t create a single Super cockroach nor Giant man.

Genetic mutation might cause the abnormal development or

abnormal growth of the cell or organ (which was called Cancer)

if not die straight, but to have a chance to create any distinctive

new feature to the species is a rare rare occurrence.

To see what is natural and which is not, or how far we can go is a

very difficult question (unlike Activists are shouting) = may be

our useless ideological imagination (and a want of nice smell) is

creating more trouble.  😀

Cherry in Focus-Shift blurr

Don’t panic on your eyesight. It’s not your eyes.

The picture here IS shaky !   😀

The photo above/top was the photo, made by a “Focus-Shift”

(while the shutter was open, the focus has been moved) =

hence created funny blurred image.

The lens used was a specially modified Canon EFS 18~55mm =

(modified to fit onto 5D and its focusing motor has been made

to work with external signal)

—– the photo below was a normal shot for a comparison

(same lens but without focus shift.)

This cherry IS the same tree which I nicknamed the

Perpetual Cherry, since it’s flowering even in the Autumn.

And she was photographed here by the same modified

18~55 mm lens though, this focus-shift technique doesn’t

necessary suit for this shot.  😀

(= so, it’s just a demonstration to see the effect)   

Unlike the other soft-focus lens which gives only a fixed

focal-length and it’s viewing angle, this focus-shift

technique with the zoom lens gives more freedom —–

and a fun.
