At 70mm it's still not that great to be honest...definitely wouldn't use "equal"...just cropped with Preview on my Apple Macbook to close to ~equal sizes...

I have said numerous times in this thread, that upper left corner, which you decided to show, is clearly faulty on the 24-70mm, and even with it performing badly, it is still about the same as the OM image. You can clearly see from the other areas that for the same field of view, it is capturing significantly more detail than the OM.

Will you notice in a 20x30 print? Probably some. The image resolution factors into the system resolution of the print.

I didn't look at the 24mm full sized images, but you are welcome to, if you crop to same resolution, and I wouldn't be surprised if the OM is as good in the corners there since they 24-70mm is not really great in the corners at 24mm, but I would try more than one side/corner.
