I ran THIS version (a rental from LensRental) through FoCal last week, and it required a +2W/+3T AFMA, then took it to my next assignment. Of note, I rarely use my 24-70 Mark I for sports because even with AFMA, it was never 'sharp' enough for enlargements.
After using this Mark II lens for 2 hrs, I was having lens envy again and was bummed I had to send it back. Then I got an email from Amazon it was available - so I ordered and received it yesterday. For one night I had both copies.
No copy-copy variation that I could tell, but because the first was a rental I didn't save my original FoCal files - stupid me.
Then (really stupid me), I got another email that my 'preordered' lens from B&H shipped - oops, forgot to cancel that. Now I have two copies to compare, and one to return. I'll be spending time in my basement with FoCal, and I'll also be out and about for few days doing a direct comparison. I'll post the FoCal reports and some other test shots for these lenses on all my bodies (7d/5d/1DIV and 1Dx). While I may not be as thorough or scientific, I'll share the images from all 3 to let you know 'just another fotog's opinion'
