Pixel Peeping: Full-Frame or M43?

Just for the fun of it, I thought I'd post a few pictures.  First question is:  were they all taken with the same camera?  If not, were some taken with a Full-frame?APS-C?  M-43?  And gosh, what about lenses? Prime? Zoom? Kit? Hint: I own a Nikon D800, Nikon D7000, Olympus E-PL5, and Olympus E-M1.
