i was just wondering if my sigmas are supposed to be this way... on my old lenses for my olympus 35mm, to focus to infinity you just turn the focus all the way untill it stops, but with these 2 sigmas for my xt, the infity focus is actualy a little bit to the left of where it actually should be... is this how they all are now?

All lenses are like that (and not just Sigma)! :idea:

Even the old Carl Zeiss on my Hasselblad are doing it
-> You'll also notice the red mark (for infrared wavelenght) is sitting to the far side of the infiniry mark, if it's there...

but i've also noticed that the autofocus is not completely right, could there be something wrong with the calibration on the camera or the lens?

What two Sigma lenses are you using? Maybe I have the same. I'll check mine.
