Stacked Lock Pin

Locking pin(1)-SZ lens

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

Locking pin(2)-5-002

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.) 

Locking pin(3)-5

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 !

A09A7715

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.   🙂

Well, having pretty noisy firework somewhere outside, it seems the new year has come. —————— ( not much significance to Zennist though — )

Without cheating, this IS really the morning sky of the first day of the New Year.  (1.1.2018  7:56)

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.)  😀

G10 Lens

G10 Lens(1)-A09A7667Generally speaking, the converging lens was designed to project an image — and supposedly a good image.  So, whether it was a cheap toy camera, one time use camera, their lens was designed to make an image as good as its cost allowed.  Its mean when I re-use those lenses, naturally they create quite usable images. (and from their deep depth of field with rather small iris, those images were somewhat focus-free)  But, even among my homemade lenses, if the lens came from somewhere which was not expected to form clear projection (by its lens own), the image was rather hope-less (without having the other lens to compensate the aberration together)   A Lens, which I scavenged from Canon G10 compact camera was that kind.

G10 Lens(2)-5

Photo left was a PENTAX Zoom compact camera.  From this one what I utilized was a mere lens barrel.  And from the photo middle, Canon G10, compact zoom camera. From this massive Hi-tech camera, what I found useful was just a front element of the lens, that’s all. (Like a stepper motor driven F-aperture, stepper motor driven focusing unit etc etc — not mention the screen system, image sensor etc may be used “one-day”  😀 )  And the photo right was the finished product, G10 lens for Sony A7R. = Looks cool isn’t it !  (sample photos which I said hopeless quality may come soon)  😀  (Zen Buddhist would say that, Even a hopeless lens should have a Karma which made him to play a role.) —– Incidentally, today (06-12-2017) was the exact 100 years anniversary of the Independence of the Finland —– Kiitos !

Halina Lens

Hong Kong based Chinese Co. who made Halina camera, Hakin was an interesting company.   In fact, Halina itself was an utterly insignificant cheap camera still, they started to make the cameras as early as in the 1950s = started about the same time to many Japanese camera makers.  They all started to make cheap tin-toy cameras.  From there, the Japanese camera industry developed and evolved to the today’s Hi-tech industry. 

In contrast, Halina stayed almost the same position since.— or, they might just stick to the cheap products to sell in the poor country.  —– I would say they were serious people though, they only managed low-tech, or they never wanted more.  (It might be an old Chinese philosophy to know the position !)   (Still, they made TLR (ish) camera, Auto-exposure camera even 8 mm Cine = surprisingly many many cameras.)   It seemed, they try to survive against digital camera (unless the PC / Printer was handy no print to give to the friends ) still, phone camera killed them off.

Halina camera(1)-001

For me, it was yet another Toy camera lens still, yet another try.

Halina camera(2)-001

In most of the case, so-called Focus free was done by the smaller F-aperture’s Depth of Field.  So, instead to have focus free, I emphasized even stronger blurred image by removing the small F-aperture (iris) (= hole in a plastic = Photo left)  Then, the Lens alone was mounted in the center of a metal panel of the camera mount (photo middle) —– Then, on the camera (Sony A7R) (Photo right)

What the photo looks like with this lens was —–

Dork(1)-E

(Those photos were from the Dorkbot gathering.)

Dork(2)-E-001

Dork(3)-DSC07559

Dork(4)-E-002

(Not the best occasion to test the lens still, the lens could handle the very tricky lighting condition rather well ! —– Other than the big halation, the images were quite normal aren’t they.)

XP Again ?

A09A7600It’s not right.  The HP laptop, which I’ve been using for net connection, suddenly died. In the righteousness of the eastern heaven’s standard, such unfairness shouldn’t be happened to such nice man like me !  😀   Theoretically, I can still check Email or my blog using my phone though I wouldn’t do such awkward work.  HP seemed to be hopeless. Even worse, it’s on Sunday = no help. My friend in the WW workshop texted me “It will be saved” though, I can’t wait till Wednesday meeting.  With a kind of last moment struggle, I tried to revive long dead Toshiba with XP on it. —– Basically, this one is working except the connection to the net. (MS said, that they can’t configure) THEN, if MS said so, how about IntelPROSet Wireless ? = Oh !  It’s works.  Then configure its connection with the router password etc etc. (so-called tinkering = and update many program)   😀 

Desktop5-001

It was a funny situation.  Window was saying that they no longer support, still they supply some update for XP.   In this way, I managed to access my Email and a lots of lots of trouble, reached to my blog (this one) —- still, in a certain extent it IS working !

A09A7606So, somewhat sneaked out the trouble, and while thinking whether HP could be repaired or not or buy new one —– I’m testing this one (= TOSHIBA saved from a scrapyard) to upload a new post. (while finding out loads of mismatch.  😀  )

Still it’s a fun !   Honest.

6 years of Zero

I know this DJ, Bradley Zero nearly 10 years.  On the beginning, he was DJ-ing in a local caffè where I was very frequent. (I was using their Wifi) —– funny story was that when I was frequent, they became very busy but, when I stop to go, soon they lost Licence.    (It’s mean, the DJ lost a job too.)  (Mind you, it was a sheer coincidence = I didn’t give any hidden political maneuver nor Voodoo curse kind. —– still this kind has been often happening to the place where I go.)  Then a while later I bumped the guy carrying his DJ gear to a local club and told me that he is going to play there.  So, I went to that club and became a kind of regular.  And so on so on many years past, then he formed a company called “Rhythm Section” and he became international too and so on. (What makes this guy remarkable was, that he was very modest still having a firm confidence to stick to his way, literally single-minded and building up his collection of vinyl and the reputation) —–  This week, he sent me an Email saying that they are going to have 6 years Birthday session. 6Years-Zero-000Zero put me on the guest list.  I went there with my Disco-costume = Rotating LED Vest.  (They got many DJs and play a kind of Dub, some are nice and good to dance.)   Anyway, I enjoyed being there and danced reasonably well.  (Though, it’s rather annoying,  these days people videoing other’s dancing with their phone = still, it might be a sign, that my dancing was not slow down or dead yet.   😀

Looks rather normal picture was taken by so-called Fun Lens.  Fuzzy images were taken by the Gaudy Lens, and if it was very fuzzy, they were done by the Mag Lens —– but I don’t think you ever bother to know.   😀

Autumn Color

Fall Color(1)-DSC07415

Those photos were taken by a single glass homemade lens, called Gaudy Lens on Sony A7R Camera —– you may wonder why needed to use High spec’ camera = the matter was not the spec’ but its small size.   😀

Fall Color(9)-DSC07456

This last photo was by the Mag’ Lens, not by Gaudy Lens —– any way looks the same = doesn’t matter.  As those both lenses got a lots of halation, picture never looks sharp.    Yes that’s what I wanted. = I just wanted atmosphere, or Impression.   In that requirment, those lenses are doing good job.   😀
