Aren't super speeds wasted effort past a certain point?< That's true. The colour splitter block has an aperture of around f1.6 limited by pure physics. This dictates the maximum aperture of the optical path so a faster lens is wasted. That is one of the reasons that a single chip camera has always interested me - no splitter block so you could use as fast a lens as you like! Perry Mitchell Video Facilities http://www.perrybits.co.uk/ Everybody: Welcome Panasonic as a Lifetime Benefactor - "Perry" Most folks here know that I have a running battle with Marketing BS, and that occasionally I find myself fencing with Jan Crittenden. She sometimes objects to my Anglo-Saxon directness but fights a good fight and off the list has been very helpful to me. I just want to go on record to say that Panasonic are very brave to stick their neck out, or at least to allow Jan to stick her neck out, and I cannot imagine but this will improve their standing with this community. JVC have regularly had contacts on the List and it is thus to their utter shame that we get a big fat 0 of communication from the big S. So, about that ridiculous 800 lines of res . . . .
