I have the Canon EOS 650D with Canon 50mm f/1.8 II lens.

After some tests I mentioned that I have ~1cm front focusing (see this question).

Is there any way to calibrate Camera/Lens without disassembling them?

I wouldn't panic just yet. As noted in a comment to the other question, I don't think your results are quite final yet.

Assuming there is an issue, there's one way: sent them together into Canon for service. They may do this for free (Pentax did with my K10D, before Pentax started including a micro-adjust feature on their cameras), but may charge some (I wouldn't be surprised if they rule this as within acceptable tolerances for a $100 lens). They'll do the work on an optical bench and get it just right; if you send in multiple lenses, they can test the whole set and select the appropriate compromise (the camera probably doesn't have a way to remember different settings for different lenses, as a higher-end model would).

Other alternatives are:

  • use live view and contrast-detect focus when critical focus is crucial.
  • or, manually focus.
  • learn to live with it; it's only a little bit of focus error and if you stop down a bit it won't matter.
  • and, make sure to buy a camera with focus adjust as a user-accessible feature next time.

  • \$\begingroup\$ I'm pretty sure none; this is one of several reasons I recommend people who are serious about photography skip the "entry level" and enter a little higher up instead. \$\endgroup\$

  • \$\begingroup\$ Wait, actually, the Pentax K-30 does. In general, the smaller brands are more likely to have advanced features on their entry-level cameras, because the bigger brands have to worry more about competing with their own higher end. \$\endgroup\$
