Thanks for clarification. You saved my lot of time.

I am curious to know if there is any way to insert viltrox, metabone or any speedbooster in between XT2 and Native fx lens ? Such as if i use 18-55 f2.8-4 kit lens then i have to put it at f4.0 for constant aperture. On other hand if i use speed booster then i can have f2.8 constant aperture equivalent to full frame focal length with greater constant dof without buying 16-55 f2.8. I am using only manual focus and aperture. So it will be ok without camera/lens communication. Just need to insert speedbooster in reliable way anyhow.
