macro, it is not so simple

As always, any problems with the joint "command-delivery".
As to make an assessment of the windscreen ???
This is much less the product technical aspect (practical since it adapts to a wide range of diameters of objectives, and the optical quality is up) than what falls use.
You still have some "addiction" photographer (on the right lens zoom, focus on a moving subject, if only because of the wind ...) to control everything it can bring the windscreen.
Courage so ... but the results are up.
Recommended product, but with the "reserve" stated above.
