New camera problems...

[ChromeScholar]

Last week, I was using a Canon 80D with a Canon 70-200mm f/4L lens for bird and wildlife photos. My wife was using a Canon Rebel T5 with a Canon EF-S 55-250 f/4-5.6 lens.

As of this morning, I am using a Canon 5D MKIV, with the same 70-200mm f/4L lens, and my wife has inherited my 80D, and has the 55-250mm f/4-5.6 lens. All well and good, except...

My wife has gotten used to using my 70-200mm lens, and the 55-250mm just doesn't match up. So now she wants to keep the 70-200mm lens, which means, she says, I need to buy a different long lens for my 5D MKIV, maybe when my 2nd quarter bonus comes in.

I'm thinking maybe a 100-400mm, or a 70-300mm.

Guess depends on what you need. Do you want to be able to zoom in further...then go for the 100-400. If not stick with the 70-300.
What's the f on both of those?

Both are f/4-5.6, which is fine for most wildlife.
