The 35LS and 32 HR-W are very close in fact center shots from both are hard to tell apart. On a tech camera you gain movements with the 32HR-W, but these are also a bit more limited on the larger sensors especially CMOS. But the ability to use tilt is a nice feature on the 32 HR-W.
For the 35LS, it's corner to corner sharp, does not require the Center filter, has a quiet and fast AF motor
Both are massive pieces of glass, heavy and delicate to use in the field.
