Isco Gottingen 1:4.5/50 Enlarger lens

This video was made for a different project. Isco Gottingen enlarger lens 50mm f5.6- f11
Due to this lockdown, I was looking through my hard drives and found these clips and thought I can create a video. That's kinda simple exercise =).
The lens is small and made of plastic, got only two aperture blades. It creates very distinct visual effects. Not very good for everyday use, but is sharp at f8.
I have two Isco Gottingen enlarger lenses. The other has five aperture blades but suffers from ghosting, not sharp, it's blurry.
This video clip wears made in Mugdock Country Park, Mugdock wood. It was really hard to find some insects, It was an empty forest. Although youse some ants and mosquitos. I am not Scientist
and I don't know much about the insect. Possibly it was a hot day.
