5D, 85mm, front focus and sigma 150mm macro.

Hey guys, I'm new in the forum but I need to ask a question, I bought an 85mm f1.8 a few months ago, when it arrived, I noticed it had back focus problems, so after testing, I concluded that it really was, by around 1", so I sent it back, got another 1 and same problem, back focus by 1" (must be same batch production), so I sent it to canon, had it calibrated and came back, not it has around .5" back focus, sent it back, and it came back okay.

A few weeks ago, I was shooting our school intramurals, I noticed things were a bit blurry even with flash so I tried focusing and manually adjusting after, and notice it was front focusing by 5feet at 30ft distance. But up close, it seems to be okay.

So, my question is, is it possible the lens is okay up close but is front focusing at far distances or is it really front focusing but just a lot more obvious when it's far away?

2nd question is, would it be better to have 50mm F1.8 and sigma 150mm instead of 50mm F1.8 and 85mm F1.8? Thanks a lot and sorry for the long story...
(By the way I'm from the Philippines, so return policy and Canon service might be different.)
