I'm intrigued by this function. As I understand, it can only be used in AF mode, and with Canon lenses. (Obviously in MF, you do the focusing, so AF micro-adjustment doesn't apply).
From what I read from canon - being the most reliable source of information - it is generally not needed. Only if the camera/lens suffers a drop etc...
So, why then on these forums - if you do a google search on this theme, lots of results come up referring to photo forums- that loads of people have to calibrate their expensive camera and L lenses because their L lens either front focuses or back focuses and hence needs to be calibrated!! To me, this doesn't make sense. As far as I can tell, my lenses are fine - and I don't own L lenses. Does this mean, that cheaper lenses i.e. Sigma are better at focusing?
I think that because we have this function, it is a good selling point for Canon - we can calibrate our own lenses.
But I also think it has created another problem because nowadays we are obsessed with sharpness - hence HD TV, lenses being clearer/sharper than crystal!! So unhappy customers still send back their perfectly calibrated camera/lens as being unsatisfactory! As digital technology increases, we are getting more and more obsessed with things that make little difference in real life.
The old motto; 'If it ain't broke, don't fix it'
Thesedays we are fixing things that ain't broke!
What do other members think about this?
I'm intrigued!
Do other members have problems with their L lenses and Canon lenses in general so much so that the micro-adjustment has to be used? If so, what are your adjustment measurements?
I will also add that I think once again sharpness and focus is subjective. I think the micro-adjustment focus can be compared to sharpness as seen through the USM in Photoshop. What is sharp/infocus for one person is unsharp/out of focus for another!!
