Released today. My pre-order is in and I can't wait to get it in my hands to do a bit of birding with the FW4.10 on the Z9.
Anyone else going for this one?
Is it going to be your main 600 or do you also have the f/4.0?
Are you planning on getting the 180-600 to go with it or will you use the 100-400 S for the in-between?
