To use any filters with the LA7200 there are a couple of methods. The most obvious is to use a matebox and either 4"x4" or 4"x5.65" filters. You can also use the Cinetactics matteblox (MB145A) with their fabric holders and either of the two sizes (the large is better when shooting full wide). Another approach is to use optical resin filters and just grid away a bit of the corners and then attach them to the inside of the lens shade (Velcro works fine for this). Frankly a UV filter isn't really needed outside of the mechanical protection that it offers.
