As we all know, that stands for Florida Scrub Jay In Flight With Acorn. The 300 2.8 is somewhere between Florida and Illinois jammed in a box with bubble wrap and styro popcorn so I dusted off the old 300 f/4, attached a D7200 and chased Scrub Jays out on Merritt Island. It even squeaked a little for the first few exposures than it kicked in. 1. 2.
