Tamron 150 500mm f5-6.7 Di III : This lens is AMAZING!! 

You have a nice backyard Mr. Wiehe, you also have a lot of birds.

You should also try taking pictures of killdeer birds if possible.

Fantastic and fun format... I love the style of your edit on this one. Yet, even more I'm so envious of this kit that you rented. The lens is nuts, packed full of features... and the A7CR!! I'm dying to try it out now too. I might have to go to lensrentals now. Great shots too and congrats on your 27th year of teaching

Liking and commenting for the cheeky edit cut into you wearing a cycling jersey. Enjoy it seeming like you have fun making these things, good stuff!

I love how clear you speak. Very engaging video and clearly enthusiastic about what you're talking about. Pleased review more lenses!
