I've an oncoming trip to Europe and am in need of a zoom lens that will cover the 24-70 mm range. The ideal purchase is of course the EF 24-70mm f/2.8L II USM—and then I wouldn't have to start this thread—but that might not be doable, and thus I'm forced to look at two alternatives: the EF 24-70mm f/4L IS USM or the EF 24-105mm f/4L IS II USM.
Anyone knows if Canon got around to fix that focus shift/RSA problem on newer copies of the EF 24-70mm f/4L? Apparently, barring that issue, the lens in question has better quality than the EF 24-105mm f/4L II.
Those of you who own these last two lenses, I'd appreciate your input.
Of course, whilst the trip is the main pressing reason for the purchase, I do want the new lens to join my professional toolbox: for now I've covered said focal length range with primes, but a zoom is long overdue—changing lenses isn't always ideal.
Thanks in advance.
