Body and Lens calibration (Canon).

Yes
Have been thinking and wondered if anyone has had their body calibrated to factory zero and their lenses calibrated to their body. This is for AF optimisation only. The reason I ask is, seeing as you can adjust some bodies with MA AF
, I spoke with a local Canon service centre this afternoon and they said they can zero out the body and then adjust the lenses if required.

Just wondering what peoples thoughts are on this?

Cheers
 
You can do your own auto focus lens calibration in just a few minutes per lens. Look up Focus Pyramid in google. It's 10 or 20 bucks & does the same thing as the $80+ calibrators do.

But you need a body with micro focus adjustment, right?

Since mine doesn't have it, I always send it to CPS for a calibration with each new lens, especially the ones with larger apertures. ;)
 
Honestly. There will always be lens to body variances. Knowing how much either front or rear focus variance there is will help you in the field. If Canon calibrates your camera body to say a 50mm 1.4 and it's perfect, chances are when you snap on your 24-70 or 70-200 it will no longer be. This is simply the nature of the beast, they must try to get the best AF possible across multiple lenses which is impossible. When you use a focusing tool such as the Focus Pyramid, these discrepancies will become painful apparent.

So... Now what. If you find that your 24-70 is rear focusing, even though your camera body will not allow you to set micro focus, you can adjust in the field. Example. If you want your subjects eyes to be perfectly clear, you would aim for the tip of their nose.

Knowing by how much and in which direction (rear or front) each lens is slightly out gives you the information you need to create sharper images while in the field.

Hope that help!

Fond regards....

I have spoken with a Canon service centre and they said they could check the body, set it to zero if required and then calibrate each lens to the body. Does this sound right?

But no UK distribution by the looks of it.

I emailed them and they said they do world wide shipping at no extra cost.
