Again with the Canon EOS 7D and the fantastic EF 70-200mm f/4L IS lens. Embiggenate it and bask in the amazing detail of this squirrel, who was probably ten feet over my head in a tree.
Basically a 5D with an 18 megapixel APS-C sensor in place of the 5D's full frame one, the 2009-vintage EOS 7D was Canon's workhorse crop sensor body for years, popular with airshow buffs, birders, and anyone else who wanted a bit more reach with their telephotos before being replaced with the 7D Mark II in late 2015. These days they're as cheap as $130ish at KEH if you don't mind BGN (bargain) grade. (I don't. KEH grades their stuff so conservatively that pretty much everything I've bought from them has been BGN and I've never had to return anything.)
