Put the 300+ the TC on the 7II today and again the "L" lens shows its stuff. Plus a couple of opportunities didn't hurt, either.
Was focusing in on this Harrier when Nan, the local bird lady start shouting "A male Harrier-the Blue Ghost!!" Guess not seen that often and rarely this close. So, good fortune to have this occur!
And then a Cara Cara flew by! IMAGE LINK: https://flic.kr/p/RGtjtS 20170315-6E7A5183-Edit.jpg by Roger Kortemeier, on Flickr
I was a happy camper.
Thanks for looking.
