what a mess. i have been swapping lens elements. i have a fisheye, the lens elements from a 50mm  and the small glass elements from a canon powershot. so far i have spent about a week just swapping them about. i think that as of last night my understanding of how these elements make work together to make a lens has increased dramatically to about 1 %.

here is one combo that didnt work.

this one was a bit of a milestone. the first two elements of the 50mm lens have been reversed and i added the second last element from the powershot lens. it would not quite focus but the field of view was about the same as a 35/40mm lens on a 35mm camera.

this is essentially the same setup as above except the two pieces of glass from the 50mm are now the right way around.  field of view reduced but closer to focusing. 

almost any change i make to the lens results in a macro lens. here are some pixels.

here are slightly more pixels show that the field of view is increasing as the night wears on.

whoa its almost a fisheye. 

there it is.  a large step backwards.

now thats more like it. still cant focus though.
