My new carry-everywhere camera
1951 Ansco Speedex 45 'Special'
With Agfa Apotar 85mm f/4.5 lens in a Compur Prontor-S shutter
Only slightly bigger than the Holga when opened
But quite a bit thinner when folded up
Sadly, the 50-year-old bellows has several pinhole light leaks (Blue LED flashlight inside camera)
A homebrew solution
Looks nice and opaque
