'Ive noticed this with a lens before but I cant remember which. Clearly its one I dont use very often so that may well be the same lens as you.

It's not causing me any great heartache, but I'm curious as to if it is a fault, design, or something else.
With the aperture fully open I cannot always get focus lock at 28mm. I can zoom in to about 35m and get lock on the same object straight away. I live with this by then stopping down to allow for the different focal length.
Now, this camera has been dropped and DIY repaired, but this doesn't happen with the Tamron 70 - 300 I also use on it.
Could it be that the sensor has moved slightly, or does it sound like a lens thing?
