We spend enough time taking pictures of large objects at close range (and taking pictures of very large objects at medium range) that I had been considering picking up another fisheye for a while.
That’s how I justified it to myself, anyway.
Here’s Invalides through the eyes of a salmon, if salmon could breathe air and walk around as opposed to gasping for air, flopping about, and hoping that a wandering sushi chef doesn’t observe their foray into Paris.

Not that interesting at first glance; the cobblestones, however, make the distortion evident, as do the apparently concave walls along either side of the frame.

Large scale indoor photography: the reason I bought my first fisheye several years ago (that and boredom, I suppose).

The tomb of Napoleon as seen from above. The framing is slightly off, but I like this picture. A lot.

The ceiling of the tomb: Another instance of large circular object plus spherical working fairly well together.
