Further modification

As I mentioned on the previous post that the 110 instamatic macro lens needs the helicoid focusing —– I did the work.

Photo right showed the finished work together with 60 mm Extension ring = both Rear lens cap and a camera body cap were fixed to the left over can !

To put a focusing helicoid, the barrel (water can) was cut first (Photo left) The internal diameter of the can happen to be 64.5 mm which was about match to a 58 to 62 mm step-down ring = so, it was connected to a 25 to 55, 58 – 58 mount focusing helicoid from China. Then they were connected to the Nikon Z with 58 to NZ reverse adaptor. (Its mean, to use a 58 mm reverse ring, the lens can be connected to any other camera as well)

Here, everything was conveniently happened to match well. —– in this kind of the work, it is always the luck of “Happen to be” works. When you need, you may find coveniently matching component etc or got pretty good idea etc ( —– If it was not on your case, think about = you might be rued to the God in your life. ) 😀

Photo left = Helicoid was shortest 25 mm, Middle = Helicoid was 55 mm, Right = + 60 mm extension ring

With this modification, the size of the subject could vary from 6.5 mm to 9 mm (x5.5 ~ x4) (with extension ring 5 mm – x7) and the focusing became very easy. = I did Nice job.

Cicada ?

I don’t think we can see a cicada in this country —– other than a its tiny cousin called Froghopper. —– still, I never seen such highly decorated costume on them ! = I was very impressed !

The photo left showes the size on millimeter scale = about 6 mm. Note the size of her hind leg that was where her nickname Froghopper came from.

While tidying up the desk I found a small dead insect among the dust. For most of the eyes, this small bit may not have any significant meaning though, I came from the country where the noise of cicada singing fill the air of sommer all the time (even in Tokyo area) I wouldn’t miss “I know you well” —– the insect was not exactry a cicada but a kind of froghopper. Still, they got the typical same shape.

So, the 25 mm 110 Instamatic Camera lens, reverse mounted to the can which can give about x6 magnification = the result wasn’t too bad for a cost nothing junk —– (may be I should give a helicoid focus on top for a ease of focusing.)

Rice Beetle

Rice Beetle(1)-A09A8055

This is the Rice Beetle I found in the Italian rice after more than 60 years lapse of time.  When I was a child, we were told to pick up and remove the rice beetle from the rice, before the mother cook it.  So, we spread the rice on a news paper and corm it to sort out the beetles.  It was the norm then that the rice was infested by the small beetles, elephant rice beetles.

I don’t remember exactly when its became we no longer needed to look for the insects. Anyhow, when the Co-op rice producer started to fumigate the rice with insecticide gas, the beetles were disappeared from the rice.

Rice Beetle(2)-000Many years ago, when I demonstrated the Japanese cooking to my friend’s family, while seeing me washing the rice, a daughter of the family shouted “Hey mum, he is washing the rice” —– it seemed, that the family has been eating the rice without washing.  Then the Mum started to preach me that the goodness of the rice is in its brown skin and the bran, therefore if we wash the rice, we will lose its remaining goodness etc.  So, I told them the story that there used be a lots of insects in a pack of rice and the reason why they disappeared was because the insecticide fumigation.  To wash off its remaining chemical is far more acute problem than a bit of nutrition. 

To take a photo of this tiny insect, I needed to use x5 magnification.  (Look at its magnified details, I noticed that this carcass got only two pair of legs = its mean the chest and the head was missing. )    Among my homemade macro lenses,  I chose to use the Instamatic Macro and the LED illumination.   Still, it was always the case, improvised Hi-magnification macro is very awkward ( = x5 magnification means the image is 1/25 dark, needs minute minute focus, sensitive to the shake 5 times more etc) — nevertheless it was a fun, especially, this was the record of the very rare encounter = I met this old friend again after 60 years absence.  I was really grad to see that they ARE also surviving somewhere on the earth.

Moth

Moss(1)--001

(It seemed, those photos were the color comparison sample of the lenses.  Left was taken by a current Canon EF macro but the right was taken by a lens from a Kodak Instamatic mounted on an aluminium can in reverse direction. — See next photos)

The old lens for a film may be adjusted to the color compensation on the print making then.

Moss(2)-Instamatic-006

Monstrous home-made lens is still working as a macro lens though, not very easy to use (Very dark with x6 magnification = you don’t know where you are watching)  —– Yet still, think the cost = don’t ask too much.   😀 

The small moth parched on a washing-up sponge must be a survivor (or, could she be the one waiting next spring ? — I’m not sure)
