I am gearing up for a new project: shooting historical buildings from a close distance, so I need an extreme wide angle lens. I am currently using a Canon 6D with a 17-40mm f/4L, but I need a wider lens. I am considering a Sigma 12-24mm or a Samyang 14mm. I would like to know if anyone has experience with both lenses on a 6D (or another Canon full frame camera) and could comment on performance and specially if the Sigma is significantly wider than the Samyang (I could not find pictures of the same setting shot with both lenses).
Thanks for your opinions.
