There isn’t all that much to say about this filter. I kind of got it to keep myself happy until I can afford a good quality, variable ND filter. Once I can get that I’ll be all set on the filter front but this piece of glass should do a decent job until then. This particular filter blocks around three stops worth of light and, as such, obviously isn’t as flexible as a variable filter would be. It seem to handle colour cast and sharpness quite well so I have nothing to complain about. A good filter that should see more use once the summer comes back again.
