Does anyone know if a lens this size can have an internal zoom movement like the 70-200? If extends like the 70-300, any concerns about weather sealing?
It would have to be at least as large as it would be as a fully extended lens. Without DO objects the current 100-400 in its full glory would be a guideline.
The standard zooms are sealed despite being variable length, that should work just as well for a telezoom.
