Sigma 135mm F1.8 or Samyang 85mm F1.4 or both?

In addition what does the 135mm give in crop mode? (something like 170 @F2.8 ?) Thanks.

I feel I would like to answer this but I don't quite understand what you mean.

With 135mm on 1.5x crop, FOV wise you have the equivalent of a shade over 200mm. Depth of field wise, it's closer to an f2.8 equivalency. (depends on the circle of confusion as to the DOF result you get)

Personally, I'd be the oddball and just go with 105mm instead.

I'm getting confused. I've got the 105mm f1. 4 but came across a guy on youtube who was using it in crop mode at 160 or there abouts at, f2 or just under. I was wondering how this would apply to the 135?

Edit: Just realised having the 105 already ties in with Kei's recommendation. I have-however ordered the 135 in addition for the additional reach it will afford in crop mode at f2. 7 (or thereabouts).
