Freewell are very expensive, their polarizers generate warm casts, and you can't use a regular cap on their filters, you HAVE to use their magnetic one (I love magnetic caps, but having the option is best).

MAgnetic filters have strongly impacted my photography. Hiking with non-photographers, waiting even one minute to screw a filter is "too long". Same with kids and the wife.
