Daniel and Neuro


Ok, I have a meeting to go to and limited time to digest all this. But I read Neuro's post on the fly this morning.


So possibly to break this down to laymans terms that maybe easier to understand tell me if this sounds correct.


That the AF point, will vary each time we engage the AF function of the camera. The amount it varies will be within the 1/3 to 1/2 depth of focus. Depth of Focus would be releated to Depth of Field but less depth because of the proximity it is measured from the camera. Because it is not accruate to the point, it produces a group of shots similar to say a rifle and scope would. But by adjusting this "group" foward and back with the AF microadjustment we are looking for more of an average of shots that are "Spot On" rather than pin point accuracy each shot.


(This would explain why it seemed harder to tune the 24mm and 35mm than the tele's. It would also expain why as you go further from your target, it might appear less adjustment is neccessary because your Depth of Field increase andit wouldincreases the area of Auto Focus ).
