focus off - what to do

I own a Super Takumar lens that I trough the short time of disposal have become fond of. But it did not take long before I realised that something was wrong. I had gotten a extreme macro-lens instead of the portrait lens I had reckoned. The world of manual focus is new to me, but I gather that I get about 3 meter of focus max, when the lens itself states 10, before I reach infinity focus.

You see where I am getting at. I am not very lens savy, but do anyone have any clue as to whether there is an easy way of adjusting the focus? Just thought I would ask. I was thinking that maybe the non-pentax m42 adapter trows the focus off balance, but maybe that is far fetched.

(For the record, I did order a certified Pentax adapter, but deliviry time of a true pentax adapter is nothing short of a disaster up here. I've waited for more then two months for the thing. According to Pentax Sweden, they will recive it in early Mars, go figure.)

If you're using an adapter that has a protrusion like this one, your focus will always be slightly off. You'll have to wait to get the official Pentax adapter to be able to use screwmount lenses on a practical basis.

The lens is a classical SMC 55 mm 1.8. If it is solved with the pentax adapter I will be happy, let's hope that it is as simple as that. Oh well, at least it's only less then a month until it arrives... For now it is not usable in the normal sense though. I'll post when the adapter arrives when I see if there is any differences.
