Thanks again to everyone who posted a reply on this post.
I have finally pulled the trigger on two lenses: 35L and 70-300L.
The 70-300L was a late decision. I think this lens will cover me for three things that I will do from time to time: sunrises off balcony at home (this is for the next eight months where I plan to shoot every morning the sunrise is good), the Chicago Air and Water Show (now that I am shooting with a FF camera, better reach) and bird photography (I have a friend with a bird feeder in his backyard outside Milwaukee, so I get to dip my toe in the water on this).
Next up is looking at either the 85 or 85L after I save a bit of money OR Canon has another 15% off sale for its refurbished lenses.
Thanks again!
