Shouldn\'t take too much to set up a test shot with a ruler and a tripod.
I would venture to guess that the following is going on:
1. the two lenses are not reporting aperture correctly... and by that I mean that 2.8 for one isn\'t identical to 2.8 for th ohter. For instance I remember reading that Sigma\'s 85 1.4 isn\'t really 1.4
2. the FOV markings on the zoom may not be entirely accurate either ... so maybe when you think you\'re @35mm on the 24x70 you\'re really more like @32mm
the two things combined could account for your perception. That or you just need to drink less while shooting.
