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.
