My Arri IIa is focusing slightly in front of the subject which I noticed when shooting at f1.5 and f2.3. I've checked the mirrors and ground glass and eveything seems to be sitting correctly so I'm a little lost? It isn't the lenses as they are all focuing at the same point, anyone any ideas?

You'll need to have the FFD checked and the lenses checked out.

Adrian is right, something is off, either the FFD or the ground glass. Take a look at this web page. It is for the Arriflex 16S, but the focusing principle on the 16S and the IIa are the same. Look at the section on FFD.

also make sure its not a filter. had a polarizer teach me that once. almost to the point i was going to box the camera up and send it in for calibration.
