I'm taking it in on Saturday.

Just to be clear on the Tamron, it works fine but the option to select phase-detect or contrast is disabled in the camera menu when it's connected so I'd say that's not a bug but an expected effect. Possibly because of the CA as tclune mentioned.

No. 'Focus Check Live View' can only use 'Contrast AF' with lenses that have their own AF motors. See page 92 of the A560/A580 Instruction Manual.

On it's way to get the focus alignment adjusted. Back to my FZ38 for a couple of weeks. Fingers crossed it's perfect when it comes back. Will let you all know how it turns out.

Just got it back from Jessops - just over 1 week which is pretty good - and on first inspection it looks to be focussing perfectly now, images sharp right down to f1.8. Will post some samples later

Great.

The AF with the Sony models I've used lately has been "spot on" with my wider aperture lenses. But, every once in a while, you're going to see a problem, as Autofocus Systems do have multiple points that can be out of calibration (AF Sensor Alignment, etc.).

So, I'm glad to hear they got it working for you.

Quick test, 100% crop, f1.8, spot focus, phase-detect AF.

Just an FYI both the camera and lens play a part in the focus equation but lenses tend to be out of calibration more so than the camera body. If its the same on every lens then the camera could be out of calibration but thats rarely the case. Most often it is the lens. The camera provides feedback information to the lens to correct but if the lens doesnt interpret it spot on and rests in the front or the back it needs to be calibrated. Im very fussy when it comes to being spot on, so much so that recently I took my lenses back twice, they left both times being out by different amounts and ended up taking them to another facility other than Canon CPS and backcharged Canon for the calibration. Its also been my experience that you have about a 20% chance that any lens comes from the factory spot on. You could keep taking it back until you find one that is or simply take the lenses and camera body in for calibration.
