Comment:

The best zoom lens tested so far, approaching the optical performance levels of the very best tele primes while offering the versatility of a zoom lens. The price is high, but considering the fact that this impressive lens can in many cases replace two or even three top-of-the-line prime lenses, it's actually very good value.

Measured without TC.
