Regarding the polarizer..., get what's available with a 43mm thread. I would consider a Heliopan or B+W but they are expensive. Cokin's okay, so are others. A good idea is to buy a plain ring or a UV (and take the glass out), and screw it onto your filter threads---leaving it on. Just get a slim line type ring. Then, when you want to change filters, you just wear out the threads on the filter ring, and not the cam threads.

That light attachment, try: www.cameraaction.com.au or go with Tim in Japan. I'll give you his e-mail if you want. That light is hard to get. Both lights available for the mx are good. Maybe even go with the Chuckmeister's Hollywood connection.

Regarding a fold up tripod, maybe someone else can help you here.

Frank, did you mean to respond to another thread? If so,
something went wrong. Perhaps Adrian or John can attach it
to the right thread?

The question was posted in another forum (announcements). I posted there saying that I will be posting here, which I did. (Thanks)
