Tamron 90mm focus issue

I've had a Tamron 90mm for a fair while now (I'm sure its out of warranty anyway), on my K20D. It lives on the camera in my camera bag. Took it out today and it just would not focus, it wasn't seeking, it would just make a tiny motor noise and then the hexagonal I-can't-focus-on-anything icon flashes in the viewfinder. After some examination, I found it was just refusing to focus on anything beyond a certain distance, because the lens has reached the end of it's travel. I haven't dropped it, or misused it, taken it out in the rain, sand, or anything dubious like that. It doesn't feel like anything other than it has reached a hard solid stop, just like it used to. So instead of being able to focus on infinity, it stops on L, it won't turn as far as the infinity symbol which I'm sure it used to. Close up it will focus all the way down to 0.29m on the gauge, which is the minimum distance, just fine. I'm not sure if it was always this way, but when it claims on the gauge to be focusing at 3m it's more like 1.5m, and 1m is more like 0.75m. Taking the lens off the camera, it doesn't change it's behaviour so I'm sure there is nothing wrong with my K20D. Got a feeling the lens has to go in for repair (is this expensive? ), unless anyone has any suggestions? TIA

So, got my estimate back. The fault requires them to "Recollimate focus system" which will cost me £31.50 + VAT. Not too bad I guess, but I am already now cautious about getting another Tamron lens.

Total price including shipping it back, £46.80.
