Back to Front , I am lost yet again ...
Hi there , Just picked up a sparkling new 24-70 F2.8 L USM !!!
yes yes I know, very heavy indeed , need to get use to this baby ...
Love it so far , Love that it has CA (Circular Aperture) ^^
OK now here comes the thing, tested the lens (second hand by the way UW serial)
and in first glance the focus seemed pretty close to dead sharp) Now I am seeing some
slight softness in the focus. Held the camera very tight like I always do and sufficiant
sutter speed , however , I took some head shots , aimed on the eye but mouth and lips got
in the sharpness I was looking for. So correct me if I am wrong the lens is "back fosusing" ?
So I went in to my 1D Mark 3 Micro Adjustments settings , and tried it out a bit , I have left it for now on +3 (Plus 3) dialed it to the right so to speak.
I am always confused on which was to correct for the micro adjustments. If it is on +3 and the lens seems to be back fosusing , my question ultimately is , in which direction should I try and correct ?
I have calibrated and tried to use the micrso adjustment guide on this forum and I came out at +3 to be in focus. However I am confused a bit ,
Thanks to anyone with the patience to indulge ,
Kind Regards
Ralph
