a dead cockroach

My dad buys and sells all sorts of things, and occasionally will buy some camera gear, even though he has no idea of its value. He recently bought some lenses, and asked me to take a look at them, to see what they were worth.

This particular collection of old lenses included a couple of Hanimex lenses, a Makinon lens, and a Sigma lens. The lenses were pretty old, didn't have lens caps, and were pretty banged up.
Some research indicated they weren't worth much - but the thing that intrigued me was a dead cockroach inside one of the Hanimex lenses, so I took a few photos of the lens and the cockroach inside it, to share on my blog.

The lens was a Hanimex 80-200mm f/4.5 MC lens with a 55mm filter thread. In addition to the cockroach, there was a lot of dirt and dust inside the lens. When looking through the front element of the lens, it looks like there is also a largish item to one side - possibly a broken aperture blade or similar.

The lens looks like it might have a Pentax K-mount, and as I don't have any compatible cameras, I was unable to test the lens, to see if it still worked, and to see how much the cockroach and other internal debris would affect image quality.

One feature that interested me was the integrated lens hood. The large band at the end of the lens with the green stripe and "HANIMEX" logo is the lens hood - and it slides out to for a lens hood, or can be retracted onto the lens, as shown in the photo to the right.

The body of the lens was scratched, and the front element of the lens had some damage, with various marks in the coatings. The rear of the lens was also badly marked, with plenty of scratches and scrapes; probably due to the lens rattling around in a bag with other lenses, without any lens caps on anything.
