Why can't Canon develop, in their Camera software a way that, when you Manually Focus using Live View at their, or your own given distance Target for the purpose of Micro Ajustment, a way to be able to register it somehow to the Camera? After all you can register a focus preset on the White lenses!
Didn't quite understand that. Are you saying if you use live view, they register the MA value based on the distance? You'd need to be very accurate with distance.

Papa.
But live view has nothing to do with micro adjust.
But then maybe I'm not reading your post correct and your thinking along the same lines as I am in relation to MA
ie: you manual focus on a target and then let the camera AF on the same target using the phase detect. The camera could then get the difference and adjust . Also I don't see why a database can't be built up for a lens , so that the camera can know adjustments at different focus distances and at different focal lengths for a zoom . The more you do it the better the performance would be.
At the moment I have a lens that's got a different MA up close to the. MA at a longer distance. So I have noted the differnt MA's and can enter the values in depending on the type of shot . i do have an average value as well that I have as the default so I can shoot various distances (I tend to stop down a little bit when using that)

Just get Focal by Reikan. Much easier.
Hi Phil,
I have no problems Calibrating my Lenses! What I am trying to say is, why can't Canon or Nikon come with an automatic way of matching any lens to the camera to find peak performance? Then apply In the Camera software! By the owner.
I think I know what you are getting at... so you basically want a feature where the camera does a phase detect AF attempt at a given target, and then uses contrast detect to attempt to improve it, and uses the resulting difference (if any) to automatically set the micro adjust parameters?

That's it,
do all that you've suggested, then do a Live View focus X 10 magnification, then whatever the difference gives the answer?
I think, the OP is suggesting to have a camera with a built-in FoCal .
There is nothing wrong with it, all FoCal does is controlling the camera via external connections, why can't it be done internally?

Ahh now I get you.
Don't know to be honest. It would seem sensible, although they would lose out on lens calibration work...

That would be a killer feature - they really should implement that
The only issue would be making sure that the customer put the camera on a tripod and used a target that was big/high contrast, and did it with enough ambient light to allow accurate focussing - they'd have to provide some instruction on its use.
