If you filter and count your images in Lightroom, what surprises did you find? Do you use your own usage data to plan to sell unused lenses / cameras? Or maybe, to change the lenses you'll use more in 2021?

The circa 1981 Canon FD 200mm f/4 macro was my #1 used lens for keepers (mounted to a Sony a7II). Merging all the extended configurations, last year's #1 lens was the second most frequent in 2019, the EF 300mm f/2.8L IS II USM (mounted to an EOS 5DIII).
