I see the point. I'm a bit of a skeptic. I wonder if your 200-400 had a problem all along, one they could see and expect to fix, but that you had not noticed?
But i guess it's possible. It just seems like the energy would have to come from somewhere. When you put that lens on, for it to bend it has to be you twisting it in place that bends the metal, and it's a solid piece of metal. It's just hard to believe they are delicate enough to bend (or conversely that you would be strong enough not to notice the increase in twisting you needed to do).
But maybe it's really that soft. I wonder what that part of the lens is made from?
