hi all,i got the siggy well over a year ago and use it regularly on my 60d,although i like it i do find it not so sharp wide open,i recently got a 70d and with the same siggy the images apear to be sharper wide open and stopped down,i didn't do any ma adjustments on the 70d for it,maybe its just me but could a 3rd party lens be more sharp on 2 similar model cameras.

Each body has its own tolerances, obviously the 70D's tolerances were more copacetic to the Siggy.. :D

70D (unlike 60D) does let you do your own focus MA, so you can potentially improve the results even further by doing that.
