you can convert the 24fps HD to 25fps very easily, for PAL usage.
I'm not sure about shooting SD onto tape, maybe that is fixed at 30fps, i'll take a look... i've never used the tape function or SD in general.
I really wnat to sell as a package right now as I don't want to be lumbered with kit that I can't use. However, someone is interested in buying just that 35mm adapter, so maybe something can be worked out.
I'll see if I get any other offers for the full setup.. then, if not, get back to you.
