By cons, it is exactly what I expected. Initially, I was pretty focused on a 300mm + 1.4 extender, but the glaring lack of versatility and the informed interpretation of the different opinions on the Amazon site, including the René Peltier that I am very grateful for his clarity, without forgetting the other, of course, and other forums, my oriented choice of 100-400.
I do a lot of freehand pictures on now. Certainly, it is heavy and bulky 100-400mm but ultimately, is handled easily and for long sessions, the monopod forget the weight of the assembly.
The big advantage is its versatility and number of shots that I made with this objective could not be fixed with a 300mm.
I can not of course compare the sharpness between the two but the results of the 100-400 are well beyond what I expected. I find photos, stitched and very sharp. Dual Stabilizer there must be a lot to do because whether for birds to test, I took a blackbird about 25m at Focal background, without feet and once greatly enlarged, well! The zoizo, it is impeccable!
Even appreciation for action shots, planes and cars and there, zooming pump is a delight to use.
In short, a user completely satisfied!
A big thank you to Amazon for the quality of its services, either delivery or customer relationships, as well as provide an objective comes with lens hood and carrying case at a very competitive price.
