So, my daughter recently bought this $2 lens thingy for me at a flea market.
It was a strange 2-part combination of a “macro” lens and a “wide angle extender”.
I had no use for the latter one but I tried out the macro lens (filter?) as It fit on one of my lenses.
The lens(es) together and separated:
The macro lens had poor optical quality and the results showed considerable softness and odd shimmering artifacts but I gave it a try and I must say that after shooting with it for an hour or so I started to appreciate the flaws. The results are weird yet strangely pleasing.
Below are samples I shot yesterday.
