I have one of these cracking 6x9 folders being delivered while I'm off on holiday. Its got the Ross xpress lens. While I'm off I will have an opportunity to get hold of a few contrast filters for it, and maybe a lens hood. Upshot is no one knows the filter size/type. I'd love to get using the camera as soon as we return. I bet some one on APUG knows what the filter size is! - please.
