Pinned post for links to lens IR performance/hotspot info

• Naturfotograf, an incredible older resource on mostly Nikon lenses, with great info on IR and UV performance
• Kolari Hotspot List, Not a ton of detail here, and some of it is contradictory since it's based on pretty casual user reporting of performance, but it's one of the bigger lists.
• More modern Nikon lens info for Z-mount users
• Samsung NX lenses
