Yes, a sheet of the solar-film would probably work best on your camera since your lens is of such a wide diameter, as buying a filter in a metal or plastic cell to fit that lens would be somewhat more expensive than just buying a sheet of the material and either just attaching it to the front of the lens w/ a rubber-band, tape, etc., or perhaps making a filter holder yourself--there is at least one set of instructions for doing so out of cardboard on the web--think it's under Baader's solar filter website.
As to the type of filter material, as you know there are glass filters, and various "mylar"-coated filters. While the glass filters may be more resilient and hold up better over time, they are more expensive and produce an orange color to the sun, which most people think is "natural" but it actually isn't, as the sun, w/o our atmosphere to look through--especially when the sun is low in the morning or evening sky--is actually quite bright white. Some of the solar film filter material, like the Baader safety solar film material, produces a real "natural" color to the sun of near-white, rather than the orange-yellow of other filter materials. So it's basically up to you what you'd like in the way of color in your images of the sun as to which type of filter material to go with. If you do want to go with the glass/orange-colored sun filters, then Thousand Oakes is a reputable company to deal with, among others. They may also carry the "black" solar film material as well, but again that produces an orange color to the sun, and I believe isn't quite as good optically as the glass filters, and/or the Baader Safety solar film, which I think most everyone ranks the highest for optical quality for photography.
Hope this helps some?
