Oops, missed that the TC was included.
However I rather grab the 500 PF then.
I feel the discussion was:
if you already own the 300PF and the TC14E3
do you really need the Z4.5/400S?
And I said: Yes, if you got enough money and space!
The same goes for the 2.0/200VR plus TC14E3
Do you still need the 2.8/300VR as well?
Yes, if your work calls for it: absolutely
