The first one is a closeup(!) shot of a relatively big (20mm total length) wasp's compound eye and ocelli. Used a 10x cheap microscope objective + Canon 7D.
The second image is (I guess) a lacewing which I found dead in front of my window in the dust. I used the 4x objective from the same cheap set. It looks like that this objective has only one lens (or a achromatic doublet).
