Probably photos published on "enthusiast" sites where camera/lens info is readily available, as opposed to stock photo agencies or major commercial publishers.

Probably photos published on "enthusiast" sites where camera/lens info is readily available, as opposed to stock photo agencies or major commercial publishers. The number of photos taken using phones would no doubt dwarf the data used here, dedicated camera/lens combos are becoming something of a niche market, albeit still a sizeable one. I use the Olympus EM-1, way down on the list. Nonetheless I found it interesting that the most commonly cited lenses used were the 12-40mm f/2.8, and the 40-150mm f/2.8. These are both excellent quality lenses, but relatively massive and quite expensive, at about $1000 and $1500 respectively. Saying goes the merit of a photograph depends much more on the person using the camera than the camera being used.
