I bought last Friday a Sigma 135mm and doing some test shots I noticed this copy is front focussing severely. I was shooting all the pictures at f1.8 I am not sure if is something I am doing wrong or it is the lens lack of calibration the reason of it.
I am posting some pictures for all the people curios to see the rendering of this lens but I have to calibrate it and try again to make sure this baby works properly.
I'll post later my after calibration shots.
I was able to shoot some pictures with the Sigma 135mm f1.8 an the Nikon 200mm f2.0 to compare IQ between these lenses, I will shoot this afternoon some with the Nikon 105mm also.
