Note right away that the testing took place on a tripod, and the quality of the new stabilization system was not verified, which is something that is extremely significant! This lens model has been evaluated by us in comparison to its previous version Canon EF 70-200mm f/2.8. Canon and Nikon are now competing with one another in the creation of cameras and lenses, the life cycle of which comes to an end one month after the purchase of either: the device works, when purchasing a new toy, after one month of work, everything will work the same way: lenses should be washed, sadly, in jpeg, Hasselblad).
