past 2 month i brough 2 new lens! 85mm f1.4g and 35mm f1.4g. and i find that is impossible to focus @f1
.4 to f2 ! it seem like it back focus. finally i brought the Lens chart to calibrate the lens i find out that even i am at +20 i still got little bit of back focus, include my 24-70, 14-24 , 70-200, any body have an d800 have this problem?
