ok, so, not knowing your photography background, please excuse any question that may feel elementary.
1. Don't worry about ISO. Nothing to do with focus. However, rule of thumb is always shoot at the lowest possible setting as to not introduce s/n ratio noise.
2. depending of the distance to subject, understand that you are shooting from a moving platform and your depth of field matters. 4.5 has a shallow dof at close distances. you could easily lose focus with drift of the inspire.
3. is your lens set to mf on the lease itself? I haven't tried it in the x5, but if the lens is on MF lots of systems, the auto focus or remote focus control won't work. it disengages the AF motor.
4. Try setting it to manual focus on the lens and then set the lens to infinity. get your aperture to f8. then shoot something 40ft (to be safe) away and let's see what you get. The doc with that should be twenty something feet to infinity.
5. don't put the lens sharpness down till we get this sorted out.
6. Yes, don't drag the shutter on moving systems... LOL great way to introduce you to motion blur
Let us know what results you get.
