Canon 16-35mm II needs adjustment. What to do?

[Photo Enthusiast]

I just bought a Canon 16-35mm II f/2.8. I don't have professional focusing tools, but have two methods for determining focus. A ruler and dollar bill, as well as another method I found using a moire pattern on an LCD monitor.

ALL my other lenses, with one odd exception, focus perfectly. The 16-35 benefits from a +6 adjustment on my 5D Mark II and 7D. I don't think it has anything to do with the properties of ultra wide, as my 10-22mm focused well on the 7D, and has a shorter focal length on the 7D than the 16-35.

Should I return my lens (had it for 2 days), have Canon adjust it, or just use the micro adjustment on both bodies?

The odd exception is: My 24-70mm benefits from a -7 micro adjustment on my 7D, but NONE on my 5D! I tested at f/2.8 at 70mm on both cameras. I don't get this one, especially given all my other lenses work just fine on both cameras.

Contact Canon for a quote... You might be surprised how much or little they charge. In my personal experience, it is pretty reasonable. You don't have to agree to it and you can probably back out of the deal and live with it.

If you're unhappy with the state of your lens, return it and try another one.

I know a photographer who is pretty picky about accurate focus and it took him six different 24-70 F2.8, before he was happy.

Have you taken any real world shots with it or just shot your ruler and $ bill, i have never tested a lens in my life, when i first got my 300mmF2.8L and got rid of my 300F4 i wondered what the hell i had done, because the first week the shots were no where near as good as the F4 but that soon changed when i got used to it
