The subject of the photo is the aperture blades of the Auto Miranda lens itself.

If the same photo can be entered into two categories, I'd like to also enter it in the "Hors categorie". I can justify this because I have managed to take a fairly clear photo of the aperture blades of a lens using that lens itself. Since the Miranda lens is mounted backwards, its main lens element was in between the camera and the blades. So, the lens took a photo of one of its own internal components.

Equipment used:

Canon EOS 60D
Canon Extender EF 1.4x II
Opteka C-AF DG AF Macro Extension Tube 20mm
Opteka C-AF DG AF Macro Extension Tube 12mm
Opteka C-AF DG AF Macro Extension Tube 36mm
Canon Zoom Lens EF 70-210mm 1:4 (made in 1986)
Zeikos 58mm UV filter
Tiffen 58mm SOFT/FX 3 filter
Tiffen 58mm Neutral Density 0.9 filter
Sunpak 58mm Circular Polarizing filter
Tiffen 58mm CLEAR/ND Graduated filter
Bower 58mm -> 55mm step-down ring
Prinz 55mm Circular Polarizing filter
American Valve RC50 2"CI Plastic/Copper/Steel rubber pipe clamp
Auto Miranda 1:1.8/f 50mm lens (made around 1979)

The Miranda lens is clamped backwards into the pipe clamp (which is
clamped around the last two filters on the camera side). The manual
aperture on the Miranda lens is held open with a broken toothpick.

That's a total of 13 items between the camera body and the Miranda lens. Plus a toothpick after the lens.
