I wonder how many of the snide posts are coming from photographers who own and use the current 70-200mm f/2.8L IS II. Just wonder.
yes, here! I find the absence of Arca-grooves on the lens/tripod foot already annoying on the Mk. II. On Mk. III i find it ... insane. Even Tamron has finally seen the light on their 70-200 G2! Lack of such a simple feature that certainly would not break the bank on manufacturing cost of a 2000+ lens, but would be extremely useful to many user and does not hurt users who don't need it ... is simply "Canon-esque". And it certainly does not increase my desire for an "upgrade".

Yes, we aren't spec sheeters like Sony people, we like real world differences.
yes. In my real world use, having Arca-compatible grooves right were they long - directly on the OEM Canon lens foot - would make a real, positive difference.
Fine. What specification should Canon use for the dovetail?

A Note About Compatibility
There are a number of companies that sell gear based on the Arca-Swiss dovetail rail. In addition to Really Right Stuff, companies such as Wimberley, Markins, AcraTech, Foba, Novoflex, and Kirk sell gear that is commonly marketed as "Arca-Swiss style" or "Arca-type" or "Arca-Swiss compatible."
Arcs-Swiss has never published a standard, so we developed our own and distributed it within the industry. In general, most of this gear is cross-compatible (but many Novoflex plates do not fit our screw-knob style clamps). For example, a Really Right Stuff L-plate will work just fine with the quick-release clamp on your Markins ballhead. And your Wimberley lens plates will work great with any Really Right Stuff clamp and ballhead. An exception to this is our lever-release clamp.
WARNING ABOUT OUR LEVER-RELEASE CLAMPS
Due to wide variations in other brands of Arca-Swiss compatible plates, we recommend using our lever-release clamps only with Really Right Stuff or Wimberley brand quick-release plates. If you own other brand plates, see this note about our plate exchange policy.
Our lever-release clamps are not user adjustable, so the plate that you use in our lever-release clamp has to be EXACTLY the right width. Only Really Right Stuff and Wimberley build plates to the same exacting tolerances. But screw-knob style clamps are much more forgiving of slight differences in plate width since you control the clamp jaws by turning the screw. So most Arca-Swiss style quick-release plates will work in most screw-knob versions of Arca-Swiss style clamps. Warning: many Novoflex plates do not work even in our screw-knob style plates.
