AJ: Thanks for your insight. I actually own the Tammy 17-50 non VR lens, and I totally agree it is a very good investment, however like all photography equipment not perfect - i.e. dicey auto focus - especially in low light.

I actually find its IQ at least as good if not even superior to the canon 17-55 which is OVERPRICED to my taste.

The secret with the Tammy, is to focus on a part of the subject with good contrast and color, for people use the eyes, or eye brows, or a curve in the nose. For "things" use a colorful contrast part with some borders or lines.

Hm, calibrating in Canon services has cost smth about 30€. Well, you won't afford any Canon lens for these money, but at least 1 correctly working lens is quite OK result :)

What if I own a Canon 60D. a 50mm 1.8 II, a 28mm 1.8 and a 15mm 2.8? Can I send them in and they'll be calibrated all together? And what would I have to pay for this? Excuse my question but I am new to this. Thanks.

NO!

Cameras are not calibrated to lenses or vice versa, this is a old wives tale.

Canon will calibrate your camera to its proper specs, and your lenses to their proper specs. 

That way, a new lens or body you buy in the future will match.

If your 60 D is off with all your lenses, get it calibrated first.  I refuse to buy one, because of the lack of Micro Adjust.

Thanks Spokane, what you said makes sens  8). I may call Canon to ask for the price for a 60D Body Calibration..
Actually the 60D qualifies for CPS, and it's still under warranty, so I may get it for free?

When I bought the 60D I knew the MA would be the only thing I would miss with this camera for now, but I compensate the last surplus of MA sharpness with my artistic talent...or at least I try to  ::)

Since its under warranty, and, presumably out of spec, they should not charge you.  It must be on your listing of equipment for CPS to qualify, so make sure its registered first.

You could send both the lens and the camera, if they tweak both to spec, then things should look pretty good.

Thanks again, that's a good point, "presumably" out of spec! With my Canon 400D and the 50mm 1.8 II I took razor-sharp photos, now with my 60D they are sharp but not as sharp as with my 400D. I wonder if it's only 'cause of the 10 to 18 Mpx upgrade, or both, that the 60D out of spec is not matching as good with the out of spec of the 50mm lens, not as good as with the 400D.

And yes, I'll register them on the CPS homepage, but unfortunately the 50mm 1.8 II does not qualify for CPS, and it got no more warranty, in contrary to the 15mm, which too got no more warranty, but it's a "CPS lens", I am already curious how much the calibration will cost..

Last but not least, how is this calibration done? How can they calibrate a lens? I am eager to know the technical facts behind it, maybe you know Mr. Mt. Spokane?

I do not know the exact method they use to calibrate a lens, it is different for different lens models.  I happen to have a Nikkor maintenance manual for a electrical autofocus lens, and it called for a specially designed piece of equipment to make the adjustments and check them, but my manual is 15 years out of date, so they likely have better processes.  I suspect that they use desktop computer driven equipment nowdays.

It is definitely something you don't do at home, its likely that very few repair companies outside Canon have the full capability.
