Instagram sucks! :-)
Fine..I remember one of my colleagues bought an EOS 450D and after a few shots we realised the pictures set to be totally horizontal were not horizontal. So either the sensor or the mirror or the penta mirror was in a bad position causing aslope/awry pictures. My colleague has to compensate every picture with a few degrees..Canon should spend less money on marketing and more on testing and quality.
For me, this is The Camera. At last, Canon!!
