I wonder if you can say what fraction of your DSLR photography is done at aperture ratios below f/2.8? Or better yet, what fraction below f/4? Answers are also very welcome from other photographers, particularly professionals.
I ask because
a) looking through the "Featured image" selections, going back about five years, I see not a single example using a lens that goes faster than f/2.8, but actual f-stops used are not listed.
Canon seems to be expecting a lot of its FF DSLR users to work within a f/4 limit, judging from its development of an extensive "f/4 L" series, often alongside existing f/2.8 offerings: 17-40, 24-105, 70-200, 300, 400, 500, 600. (Not to mention the 28-300 f/3.5-5.6L and 100-400 f/4.5-5.6L)
