<<After purchasing a 24-70 f/2.8 my images were no where what I expected. Soft eyes, things seemed out of focus, etc. I purchased FoCal to help with tuning my lenses and after wasting hours on top of hours trying to get my 24-70 tuned, the results were all over the place, so I would recommend skipping it. One time it was -16 then -3 then -11 then +4 then... then... then... then...>>

Sadly a repeat of my problems posted elsewhere with the 24-70mm with LensAlign and FocusTune much it seems to the annoyance of some! However, I do have some faith in my system, although I was losing my cool with zooms, the repeatability was much better with primes. My 300mm f4 analysis actually returned 3 times an AF-fine tune of zero! My opinion is that zooms are a hit or miss issue and best left alone. That said, I have returned all my AF-fine tune settings to zero, upped my technique as you have by increasing speed. Job done
