Looks like an ideal option indeed, especially for birding, you won't have to swap lenses and very interesting also, for birding framing a bird at 600mm isn't an easy job, when it's already in the viewfinder framing while zooming is an easier job.
My concern about this lens is it's durability, the more the zoom range, the more it has elements inside, the more it's prone to have problems and lose some of its optical quality with frequent use, especially this lens might well be used in harsh conditions.
I can't justify buying it for very occasional use, however if it were available for rent here, It would be my obvious choice for the next migratory birds season
