Malachite crystal 2

I was taking photos last night with my new macro when I reversed it to get 1:1 shots. I tried to stop down the aperture and found out that the blades were stuck. Apparently someone oiled them, or some oil got on them. You NEVER oil something like aperture or shutter blades; dry and clean are best for them.

That's why all of these photos say f32 but are mostly out of focus. The lens was only stopping down to about 5.6.
