Only reason to get this for me would be AF and size.
However: for Macro, AF isnt really a requirement and in the field you are carrying a tripod and flash with diffuser so compactness isnt a priority.
And flash sync.
Whats the flash sync for native lenses?
Iirc, its 1/1000.
Useful for Daytime macros.
AF is always a plus , for fast work and when less closeup is needed (I doubt af works well when very close with the high mag)
Smaller also means portability and better hand hold stabilty.
I am really keen if they release this.
But on 2nd thoughts, 20mm is too near working distance and maybe too little magnification.
