The differences are basically reach with the 600mm and/or teleconverters or one stop faster and greater blur of background with the 400mm at 400mm

You know what you currently shoot and are expecting to be able to shoot upon acquisition so the choice should be a reasonably straight forward one

Not wishing to hijack the thread but does a 400mm f/2.8 with 1.4 TC have the same or better background blur as a 560mm f/4? i.e. does a TC affect depth of field?

If youre are shooting a distant subject with a distracting background or are looking for best subject isolation then I have always been led to believe f2.8 is better than f4 and that the 400mm f2.8 was king of the superteles in that regard, I use a 600mm buts thats for reach
