Soft option in close-up photo

The lenses of which I dubbed “Omunifocus Lens” produces quite usable images from infinity to 0.5m without having any focus control.  Yet, it has a limitation — closer than 0.5m, the image became too blurred.   Still, if the position of the lens was adjusted it can produce pretty sharp image.   So, I ordered the close-up ring for Sony E-mount and while waiting its delivery, I took a soft option of close-up technique.  = The lens was stack on the camera mount with 10 mm high soft plastic putty. (Bluetack) = As the lens was positioned further away from the image sensor it’s enables the close-up shot. 

Those homemade lenses were mounted on the OM body cap (which can be used as a Sony E-mount body cap), so that I can change each of the lens quite easily = take one out and just stick the other.   Since its humble origin from a toy camera or disposable camera, every lens are all one or two plastic, still each of them showed the different character.  Such as the one from panorama camera got quite deep depth of field = keeping omunifocus character even under the close-up shot. (Photo above left and middle)   Still the other lens showed very nice soft image. (Photo above right) — Can you believe, those images were created by the lens costed almost nothing !   And now you might be realised that the photography even with such thousands pound Hi-Tech camera may not necessary be very precise and rigid technology or art = in fact they can be very soft.  (You can see the images if the optical axis of the lens was 15° out.)
