3 x it came with the same defect.
If you hold tablets on the lens and turning the ring to the manual focus, then increased the
Entfernungssklala and freezes.
The automatic AF is significantly slower than in the horizontal to the vertical position.
Diagnosis of Canon: Defective USM drive.
2 lenses I have it repaired.
Both were then decentered and rotten.
The 3rd I then added directly to the dealer.
Hello Canon It's still ???
I've now (actually from the desperation) a Sigma 70-200 fetched 2.8 OS.
The thing is absolute class and still about 100 euros cheaper than the Canon.
