I think it really depends on whether you need the extra reach. If not and you would find the macro capabilities more useful then trading it in for the f4 lens could make sense. Alternatively, if you want better image quality and you don't need the extra reach very often then a good option would be the 2.8 GM II lens plus a 1.4x converter for when you need it.
I have a question, should I trade in my 100-400 for any of these? Do you think it’s a good idea?
