Et plus exactement :

"There were some rumors going around that your 24-105mm zoom lens was discontinued. Obviously the rumors were untrue, but has that lens performed as well as you'd hoped?

I'm happy with the optical performance of the lens as a standard zoom. This kind of lens is among the most difficult to design because it covers wide-angle, through standard to telephoto. The ideal construction of a wideangle lens compared to a telephoto is very different. So we need to compromise to some extent. And the 24-105 has good performance for that type of lens.
In the market, its performance hasn't been excellent, but it's OK. The rumor about discontinuation came about because we can't supply it in enough volume. We forecast demand for this lens as being very low, so we didn't plan to make many. But at some point they all sold out, and we then suddenly had a lot of orders placed - but then it takes four months[to restart production]."
