Even though the supply shortage is a bummer for sure, the reason due to higher order numbers than expected, is not a bad thing in my opinion. I think it's no surprise they aren't able to ramp up production values for such a low number, high-cost and highly precise product and their statement regarding high demand for product quality is also welcome. It would be quite a PR disaster, if this lens would suffer greatly from copy-to-copy variations with maybe even some samples suffering from obvious quality issues. That's something which is already questionable in the medium and higher priced segment, but for such an high-end flagship lens, it's just out of the question.
