Lens Comparison (2)

This 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.  😀

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

The 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.

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

By the Helicoid (A) / ISO 100, 320th

By the G9 lens / ISO 100, 1250th

By the Double Density Pinhole / ISO 6400, 250th

By the G10 lens / ISO 50, 640th

By the Mag lens / ISO 50, 650th

By 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 ?

By 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)   😀 

100 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 ! )

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

By the SZ lens / ISO 50, 1250th

By 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)

Squirrel

Since I obtained some Focusing Helicoid, I’ve been testing their best use etc —– so, while testing 36~90mm Helicoid with old antic lens, watching the tree, I saw a squirrel on there.

The lens, originally for a Kodak red bellows Folding Camera, was mounted on an extension of a helicoid and working as a 175mm F10 telephoto lens. (Pretty dark)

I don’t know what the squirrel was doing there, I just snapped a busily moving squirrel. (Though don’t ask fine focus to 100 years old dark lens on an awkward helicoid. — this must be an optimum result for an inpromptuous handheld shot.)  😀

(And I don’t think this photo is showing any good quality —– never mind If I needed I could have used proper Lens. —– and I wouldn’t insist “fuzzy image” for this kind of picture ! —– You can see properly photographed catkin’s image.)

What on Photography

Although it was a bit cropped, still this was a quite wide-angle view (18mm) of a morning sky, and this was more or less the view what we are actually seeing = in other words, this IS a faithful representation of the view = and that was what we expect to a photo.  —– So, the Photo IS a COPY of the subject, therefore if the subject wasn’t there in the first place, the Photo couldn’t exist neither.  And may be because of that, the Photo competition prohibit the Photoshopped photo.   Photo has to stay as a faithful secondary image of the subject.

And this is the image of the same sky, taken by the other camera at about the same moment of the photo on top.

So, this is a tricky situation. This photo above may be seen to be an illegal image using a ready-made digital effect, so-called “Filter” such as in a smart phone.

But this is the natural character of the lens.  From the common sense, this images may not to be regarded a Photo still, this IS the image, straight out of the photographic device / camera.  (Downsized to 1200x*** and collaged by Picasa in my XP laptop)

They were the images out of Sony A7R with so-called Helicoid (B) lens. —– If the photography was a mean to express oneself, those photos may have my feeling which evokes much deeper into your subconscious.  And they were not by the ready-made effect but only one of the kind in the world. (Whether you like it or not.)   😀

.

Helicoid Lens (B)

Helicoid Lens (B) is a sister of (A).  Both came from the same Sony Zoom lens and I’m using the same size helicoid which I got from China.

So, this 18~200 Zoom lens became the SZ lens and the Helicoid A and B.  Well done.

Lens was tested while temporally fixed on the camera using plastic pate, such as whether the lens should be used reversed or not, and with smaller Iris etc. (Photo middle) In order to adjust the infinity, lens was fixed on a M42 to M39 adaptor ring on the M42 to AI (Nikon) mount adaptor. —– after the infinity point was found, the position was fixed with super-glue. (Photo right)

It seems this lens was an aspherical as the funny shaped reflection on the surface suggests. (Photo left)  This helicoid extends from 17mm to 32mm and the Lens which got about 35mm focal length can focus from infinity to 15cm close-up.  And the calculation from the exposure reading, the brightness seemed to be F2.2.

Though, this lens is having very strong aberration. ( Astigmatism ?) —– same as the Lens (A), the center wasn’t too bad but image quality was one of the worst = which I appreciate a lots.  😀     (It’s so rare to find this kind of image in the photography because, nobody design the lens like this for sale.)

(Photo here above, Left was the (B) lens in its finished looks — looks cool isn’t it ?   😀  And the right showed the Lens’ closest view, which showed its softness for comparison.)

For impressionistic fuzzy image, the poorer the lens quality, the image looks more interesting. (I think / and that was where Pinhole Photography stands) —– strangely, the close up image was rather sharp. (I mean its center was) (Photo right)  —– Whatsoever, I’m quite happy with its outcome.   😀

Helicoid Lens (A)

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.)

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.)

And the lens I used was came from broken Sony zoom lens. (In the center of the photo above, two of the small lenses)

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)

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

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.  😀

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.   😀 )

Blue Moon without Eclipse

It was a Full Moon, but we in England couldn’t see the Eclipse like somewhere else could.     Never mind, it won’t cause any misfortune.

(As always, the photo here was taken by Tamron SP Mirror 500mm F8 on Sony A7R. Through double glazed window.)  😀

Piece of Art

I’ve just received a mail, large air-bubbled envelope.  And I discovered a content, a piece of Art which could have been packaged in a heavy wooden crate.

It’s from a daughter of my friend, who started a fine art study, whom I gave a pinhole photo device. —– As a return of a 0.2 mm void on a beer-can panel, she made pretty unique image of a master piece for me.  (It’s a proof of that, a 0.2 mm void could have a trade value for could be a priceless master piece though, don’t take it for a precedence, it may not work for your case.)   😀   (A void created by a Zen master could have a significance, comparable to the whole universe.)   Believe me.   Ha ha ha.  😀

Morning SKY – 18

Took on 18-01-2018/02:41   (This photo got funny reflection of the room)

England was having only +9° weather and severe gale force wind, nevertheless the life goes on and as usual, still, a morning is keep coming.

/6:45 (ISO 800, 2 sec)

Looking out the window, I noticed rather fancy sky.   (Except the last photo, all the pictures here were taken by a Nikon mount Zeiss 18 mm lens / on AV mode)

/6:47 (ISO 800, 2 sec)

On front of my eyes, the Sky changes minutes by minutes.

/6:49 (ISO 200, 6 sec) —– When those 6sec exposure occurred, the camera was hand-held, while the top of the lens was pushed against the window glass.  😀

/6:54 (ISO 200, 6 sec)  (Notwithstanding its hand-held 6 second, the picture was surprisingly good. —– don’t you agree ?)

/6:56 (ISO 200, 6 sec)

/06:59 (ISO 800, 1.3 sec)

/07:01(ISO 800, 1 sec)  (The light in the each picture was a different aircraft —– so many of them flying)

/07:09 (ISO 800, 1/3 sec)

/07:32 (ISO 200, 1/20th sec)

/08:04 (ISO 100, 250th)

/08:33 (ISO 100, 640th)

At last, the sun came out.

/08:36 (ISO 100, 80th)

(Only this picture was taken by a homemade G9 lens on Nikon D850.)

Birthdays Party

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. 

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.

Somebody started to do a clay craft, try to show their creativity.  —– Following the foot step of Marcel de Champ I made a toy size urinary = great attempt (I think).

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 !

Omuni-focus Lens

About a month ago, I talked about Halina camera and its lens. —– A story how I made its lens to use on the Sony A7R camera and showed its sample photos.

While checking those homemade lenses, I found that the said Halina lens could, (with an additional diverging lens on front, as its focal length become longer) be used with a thicker Nikon body.  So, I further modified to add a diverging lens and mounted them on a 42M (Pentax screw) to Ai (Nikon) mount adapter. = Here I got Omuni-focus lens for Nikon DSLR. (And this work was somewhat related to the other lens)

I know, this situation is having a silly contradiction.  Why 47.5 MP Hi-Res camera need such low-Res images ? —– Omuni-focus mean, nowhere having a “Distinctive OUT of FOCUS (Bokhe) image” in the same time, no “Clearly Focused image” either.  = Just rotten images spread from top to bottom. ( More like a pinhole photo ! )   

Yet still, those photos above, both far and close subjects, it is a rather remarkable phenomenon, such a cheap plastic lens can make (a kind of) usable image in any distance, without focusing, without using smaller F-aperture.    (BYW, the last dried rose was taken with an additional close-up ring) = Omuni-focus is not necessary an almighty.)

And those comparison photos were for academic interest.  Left was by this Omuni-focus lens, and the right was in deed, a pinhole photo image !

Now, my point must be clear, not necessary only decent sharp image could be a good photo.  (Though, I’m not implying my fuzzy image here IS a good photo.  😀

—– May be not a good photo still, I found that those fuzzy images appeal to our deeper psychology. —– I had distant memories in my subconscious, I might have seen this long long time ago —– may be even on my previous life ? ? ? )
