Correct the quoted dimensions for the Z600 are 1cm smaller diameter in the new lens -vs- the E-FL version. (new Z 600/4 TC -- the diameter of the lens is quoted to be 165mm - so slightly smaller than the AF-S 600/4 E -FL which was 166mm and obviously larger than the 2 other Z super lenses).
But as you can see from the attached (for the Z400) we need to provide accurate measurements for the Zemlin solutions for the new lens -- hence the need for both lens and digital measurement tools.
I have Zemlin Hoods with Skids on them for both my other lenses and lens caps too. AND YES - having dropped a D5 with 400/2.8 attached, while on safari, which ripped the mount out of the D5 -- an insurance job -- I am legendary for my ability to drop, bash, scrape my gear in the "excitement" of the hunt/chase
