Before I picked up the Rokinon 35mm f1.4, I read a few reviews. Here is what they said about Lens with respect to flares/ghosting.
Flare and Ghosts
There are none.
Even pointed directly into the sun (I have my blind neighbor do this for me), ghosts are still nearly nonexistent.
Samyang 35mm f/1.4 (a. k.a. Rokinon, ProOptic or Bower)
The lens is nicely resistant to obvious flare from bright light sources such as the sun, but the hood works well to reduce generalized veiling flare.
Samyang/Rokinon Lens: Primes - Samyang/Rokinon 35mm f/1.4 Aspherical UMC (Tested) - SLRgear.com!
I never got any flare or ghost with the Rokinon 35mm
f1.4, even when shooting on super bright days.
Review: Rokinon 35mm f/1.4 (Nikon With Focus Confirm Chip)
I did some test shots with my K5, and wasn't expecting these results given the reviewers comments.. Should I be concerned about my particular copy of this lens, or am I expecting too much? Does anyone else see this behavior with their copy of the lens?
This is with no filter and with a lens hood (not that a lens hood would matter for some of the shots).

This I can live with.

Also, I guess this sort of fringing at F1.4 is expected.

100% crop. With and without corrections:
