This subsection is where I've put the autofocus lenses from companies other than the camera makers (e.g. third-party lenses). These lenses tend to come from only a small group of companies, with the L-mount and Sony FE-mount having the most options. At the last update to this page, the Nikon Z-mount is getting much broader support, but for Canon users, only the RF-S (crop sensor) is currently supported.
Note that many of the lenses in this section won't be found in most camera stores, but only on eBay or through Internet sites. Also, some are only sold regionally (typically Asia).
