Yeah, but Samyang lenses are all manual focus. Oh, wait...
The 24 II is a significant optical improvement over the MkI, at f/3.5 and even stopped down to f/8. It also offers the ability to change shift and tilt orientation to one another on the fly.
But...the 85L II is an amazing lens, too. I suppose it comes down to whether you want to improve the optical performance of your wide TS-E images, or have another great lens for portraits.
I think I am going to go with the 85 f/1.2, I am reasonably satisfied with the performance of my 24 TS-E Mk I. Out of curiousity, does anyone know why a TS-E lens cannot be made with AF?
