Yashica-Kyocera Macro (2)

Those two photos were the x6 shot of the Butterfly Wing.

As I described in the old post I made this lens last November

— and now, it is the time to take it out or find a good subject

to shoot on a table top.

Any how, it was a broken 38~115 mm Zoom Film camera of

Yashica-Kyocera.

To disassemble the camera is a brain game = Which screw,

where to start is quite crucial to have an easy game though,

even if you were completely wrong and made a mess, not much

damage would be done, nothing to lose but a bit of Ego.  😀

What I did with this camera was, taking out the optical unit

from the lens barrel and re-mounted it up-side-down

(front side back) to the same barrel.

(= Camera lens was designed to give the best performance

when the front was focused to the infinity, and the image

was closely projected to its back.

It’s mean, if the back of the lens was closely aimed to the subject,

the front side will make a big enlarged image. 

= this exactly what the macro photography is.)

The lens barrel was glued onto a Contax-Canon mount adapter

to be used on the Canon DSLR.

And this (improvised) macro lens gives x1.7~x3.6 magnification.

(with a farther 44mm extension it gives x6 magnification !)

—– considering its cost virtually nothing, the performance isn’t too bad.

— though, with a test shot of yet again the egg of

Green lacewings which showed Chromatic Aberration,it was

found to be not as good as Chinese cheap Microscope Lens.

(which was designed for macro work))

—– incidentally, I’m very much puzzled by this Egg —

(1) Why so many of them were found in my room = Why

the insect prefer to came and lay the eggs here.

The larvae of Green lacewings  eats Aphis kind, it’s mean

they should have chosen such kind of environment.

(2) When this egg was laid — last year ?     If so, why I didn’t

see it till yesterday = it was on my desk, very front of my eyes.

(Photo above were x2 and x6 magnification)

Taking closeup photo of rather unwilling wasp

wasn’t very easy.  🙂

(With the enlargement, flaw of the lens such as a

Chromatic aberration, became appearent.)
