I am researching the Canon TS-E 17mm f4 lens to use for architecture. I would be interested to get some feedback from anyone using this lens with either the Metabones or Sigma adapters on either an A7ii or A7Rii body.
Are there any functional issues affecting manual focus particularly focus peaking and focus assist magnification?
Is there any loss of sharpness?
Does auto exposure work correctly?
I would really appreciate hearing from people with first hand experience of using this lens with either of these adapters.
Many thanks.
