MC-11 vs MetaBones T for Canon 300mm f4L

[flyingmunkey]

hi guys. new here and i'm looking for help. the title basically says it all, but i'm trying to find help on deciding which adapter to use. i currently have the a7ii, but i have an a7rii in the mail right now. most of my glass is native sony, but sony doesn't have a good prime zoom yet. so, i'm looking at getting the canon 30mm f4L is, but i keep finding conflicting information about both of these adapters. also, i haven't found anyone using this lens with either adapter.

 

does anyone here use this combo? i'm mainly concerned about auto focus performance as i work at an airport and will be using it for (moving) plane photos mostly. any input is greatly appreciated, thanks!

Hi, here is a good resource for metabones performance with many lenses:

My recently aquired Canon 300/2.8 L USM 1st gen (no is) works very well with the metabones IVt in green mode on the A7rII. I have yet to test the advanced mode but I intend to write a longer post about this combination. Regards,
