So...putting your lens cap on might cause it to not be able to AF without taking the lens off and on?
Yeah, that's something that shouldn't have made it past QC testing.
True. It's happened to me putting the lens cap back on. It's not hard to get in the practice of retracting the lens first, though. And you don't have to remove the lens just rotate it a bit and re lock it.
I stil love the lens.
