Flower Patch (4) — by 2-Element Homemade Lens (A)


There are two “2-Element Homemade Lens” = both were based on the

(supposedly) same toy camera lens (seems to have 27 mm focal length) but

one was using HOYA short-eyesight specs lens to lengthening the focal 

length, suits for a full-frame Canon 5D.  The other was using a strong concave

lens, came from a discarded zoom’s front element, and I made this for Nikon 

(though, for this test, I’ve used it on 5D with “Nikon to EOS” mount adapter.)  

As the original lens was designed for focus-free, they are the easiest  lens to 

use = unlike Pinhole, at least I could see the finder image, still no need to focus 

= just click, thanks to the camera’s AV mode.   🙂

And the photos in this post were taken by the HOYA-Canon type.








As focus-free, the lens could capture from quite close range to the distant subject

with very reasonable quality with an added “good” softness and the good deal of

halation which makes me smile with fun.  🙂

(though, I haven’t established whether its softness was the toy camera’s inherent character

 or caused by the added lens —– whichever the cause, it wouldn’t spoil my fun.)

And the images made by the toy camera lens (hence, close-up only) was in this post.
