11 across 3 different mounts... Oh wait is that 12 across 4 mounts, since I have a Sony 18-55 kit lens too. However, 8 of these are in the single mount (Canon EF): 4 primes and 4 zooms.
That sounds insane but here in this thread I feel a little less crazy. 🤣 And all but 1 of these lenses can be used on a single platform (mostly adapted, but I'm fine with that) so almost all do get used from time to time, and about 5 are used frequently (though of course I never use the 70-200 and 100-400, or the 85/1.8 and 70-200, on the same shoot, or the same vacation).
What really IS unsound is that I'm still contemplating at least a couple lenses even though I'm probably stocked for the rest of my life actually. 😕
