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.)  😀

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 ? ? ? )

Stacked Lock Pin

When I took those photos, I’ve used additional close-up rings on the SZ lens.

Close-up rings I mentioned were those kind. (Though, this photo left was when I blogged about the lens from an Instamatic camera)  The Nikon mount SZ lens was attached by “Ai to EOS” adapter.   But the adapter stacked on the EOS Close-up ring.  So, I needed to hammer down the Lock pin to release the Ai adapter from the Close-up ring. (Photo right)  In fact I was lucky as I could access the pin —– if an EOS lens was stacked, (so, the pin was hidden inside) I needed to use a hacksaw to cut open the ring ( = the saw-dust might got inside of EOS lens and creates even further trouble etc etc.) 

What I found was, the lock pin was too long ! = It protruded from the ring, hence, even the release-lever was pressed down, pin was still blocking the Ai adapter to rotate.(Photo left)    The pin needed to cut and make it short.  And to do this, both side and other side of the ring was covered by the masking tape first, to prevent an accidental touch of a file to make scratch. (Photo middle)  Then file-down the pin (Photo right), till the pin never protrude from the ring surface when it was pressed down. (check it like photo left again and again).

Close-up ring like this (not necessary red color = blue, gold etc all very colorful) was sold in Ebay a lots, mostly about £25 for set of 3 though, I found this for £15 = may be it was “the rejected seconds” rejected from other bender = somebody throw it away = then, others picked up for opportunity (= any business is the busyness in China = remember, they made a cooking oil from the sewer remain !)  Still I’m buying a lots of staffs (adapter ring kind) from  China/Ebay —– while keeping eyes on its work (I’m not asking them to be a perfect, but at least it wouldn’t harm others ! —– since, I’m a very generous Zen Buddhist.   Ha ha ha   😀  )

It was a full moon !

In the evening of the New year’s day, I noticed a moon behind the trees.  I thought, Oh, it might be a full moon, though, before it came to the center of the window, the sky got cloudy.

Yet still, you can see the unusual “Norwegian Moon rise Photos” in the Bentehaarstad Blog. —– not only that, you will find many many very interesting topics and the photos in her blog (click the links in the bottom)  I’m sure you will enjoy them.   🙂

SZ Lens (for Nikon)

Since I failed to make the NZ lens for Nikon use, I tried it again with similar Sony lens (18~200 F3.5~6.3, A-mount lens which has been dropped and internally broken—– I think I got it for £5.)

Having had previous experience, this time I planed the lens (front compound lens element) should be mounted recessed inside of the barrel. = mounted inside still not block the movement of the zooming barrel —– and all those massive work was what I’ve been doing past 2 weeks or so. = hence no party, no dancing  😀

Whether those 2 lenses were using same design idea or not, they were having some similarities.  Front lens seemed to be about the same size and the shape, though their character seemed to be very different.  Unlike the worst lens of NZ, this SZ (for Sony Zoom) showed rather decent quality as you can see on those test shots image. (mind you, there is no iris = 100 mm lens / fully open as about F2,  but not necessary giving beautiful softness.)

Something what I found remarkable was that this SZ lens got quite good macro capability !   (Those shots above (original size) were with additional extension ring.)  (Further test shot image may come soon or later.)  😀

It’s a funny irony, Nikon lens was used for Sony and Sony lens was made for Nikon. —— (I didn’t play such game on purpose —– It was just an unintended consequence.)

F & M Window decoration for 2017

It’s an old story still, I don’t want the staffs stuck and left over.  (Get clean up before the year changes. )  😀

Hee Ha, — of course all those photos were taken before Xmas, but I was busy making a lens.  😀

And those pictures, if the image was distorted, they were taken by Nikkor Fisheye 16mm F3.5.  And the rectilinear wide-angle image  were by Zeiss Distagon 18mm F3.5 —– the rest of fuzzy images were taken by a homemade G9 lens all on the Nilon D850.   Thanks for watching !  (Don’t drink too much tonight.)  😀

Oxford Street, it WAS

I know, I should have done this week ago.  Nevertheless, here the photos.

Those window decorations were from Selfridges —– but I wasn’t so much impressed.

(Strange green colorings in the shadow area was created by the Sony image processor. —– It IS a headache with this camera.)

So, it WAS a so-called Xmas decoration. (Now there are only Sale, Sale signs)  😀 —– Most of the photos were taken by  the Homemade G9 lens.  (except last one which was by Sony 30mm F3.5 and the camera was Sony A7R)

NZ Lens

Before, I’ve made close-up lens out of a front element of the zoom lens.  So, I wanted to make something different from this Nikon zoom lens. (AF-S Nikkor 18~200 G ED)  Conveniently, the front element of this zoom lens extend  = it’s mean I don’t need to look for a focusing helicoid to use with this lens. (It’s already there.)  😀

The matter of conversion was, to mount the separated front lens unit to a camera body.  There was a possibility to make the lens for Nikon mount. —– but on the end, I found that, unless I could trim off yet another 2.5mm from the lens barrel, it was only useable on Sony E mount.  The photo above was showing how the glue-up connection was made. (Aluminium ring was glued to the lens barrel first, then it was stick to the body mount.) (First plan was to mount the lens unit to a lens reverse adapter for Nikon though, as it couldn’t get an infinity focus, plan was changed to Sony = an adapter to use EOS lens to E-mount was chosen for its matching diameter.)

So far this lens is the heaviest among my homemade lenses.  Looks a bit strange though, it would give an impression of some kind of professional gear, not a homemade mock-up.  😀

Photo above are the test shots of this NZ (NZ for Nikon-Zoom) lens.  It looks the most murky, fuzziest image out of my many homemade lenses.  It was not a kind of light scattered halation — much more fundamental = light is not focused to single point (worse than spherical aberration and the image field was curved) —– Mind you, against its focal length (about 90mm) the diameter of this lens was 60mm =  it’s mean, 90mm lens brighter than F1.5. — Well, unless it was a few thousand pounds lens, no designer would give any guaranty of the decent quality for such bright lens.—– If I could produce decent sharp image out of this lens, it is a fraud.
