Of course it was! I'm sorry... Your photo is a great example! I was thrown off by the "15mm" because I was scanning for the word "fisheye." I think the fisheye might be my favorite lens that I don't own yet. That and the 90mm TS-E.... both look like fun and creative choices.
Here's one from my favorite macro lens, Sigma 180.
Great thread and so many excellent images. Here's mine taken with the Sigma 300/4 ATM my fav lens, but I am lusting after the Canon 400 5,6 L and the pics posted in this thread are not helping either
I've had the please to use/own the 50F1.8, 85F1.8, 70-200F4L, and the 135F2L.
By FAR the sharpest, fastest lens I've ever used, with the best contrast, and bokeh is....
The 135F2L
These were taken wide open WITH the 1.4x extender:
