Pla Lens

Sorry to be too casual — Pla was a shorten of Plastic magnifier. I don’t remember how and when I got it. As I was looking for a lens which is large enough to accommodate a lens of one-time use camera kind, I just found it on a corner of my desk.

Pla on NZ7

Yet another fuzzy photo was a result of the newly created homemade lens, out of plastic magnifier and a one-time use camera. —– I have tested 1/2 lens, 1/4 lens kind though, they were the lens combined the out side of each other. = So, how about to try “Concentric two lenses” !

Godo on NZ7

(Incidentally, this photo was taken by a bit more ordinary (?) lens = Godo Lens.) —– You might say, when one lens can produce the image like this, why do we need yet another lens ?

The situation was more complicated = TO accommodate the other lens in concentric mean, I need to put another lens in the centre of a lens = It’s need to curve a hole in the centre. —– So, I improvised some tools to make a mini bench drill.

I just carried out the work = 10mm hole was drilled on the centre of Pla lens and a one-time use camera lens was inserted into the hole. Then the lens all together was mounted to the camera. It was mounted to the depth where one-time lens can make the focus = but too short to the Pla lens = hence, the resulting image was like the photo right.

(Ring shaped Bokeh was made by the Pla lens’s so-called “Ring Bokeh” caused by too out of focus lens. — it’s mean, even the “Bokeh lens” has to have about near focal length = out of focus may makes nice bokeh, but “too” out of focus may be too bad. 😀 )

So, this image was the worst among my homemade lenses ! 😀

A night sky —– anyway, we may not need much of details.

So, how about this ?

M m m m. —– It may need some improvement (I need to find the lens which can make softer Bokeh ! ) still, I like their paintary effects.

I can’t resist loving the image like this.
