I like it for when I want to switch wavelengths a lot in one day. When I am shooting the same scene with various filters on the tripod it's great for switching quickly, avoiding the long gap between shots and cloud movement for example. It does make lens choice a little fiddly however as you need to choose lenses with all the same filter size. The other issue is that it can add a little vignetting on wider lenses too.How do you like the Manfrotto Zune magnetic filter system? Looks awesome.
