EOS-1D Mk III, 500mm f/4L, 1/400, f/4, ISO 800
About 90% of Full Frame.
Required rotation and some subsequent cloning in the upper right and left corners.
Handheld from a Zodiac off of Bonaventure Island during Chris Dodds' Gannets Galore workshop.
The bugs are small flies and they were everywhere around and on the island in very large numbers.
Good news was they really didn't bother you much and better yet, they didn't bite!
