Hello
For those of you that have evoved with this system, does any one kinow if there has been a real evolution in groundglass fineness?
Also how quiet is the 400?

It is pretty quiet, but not enough to use the on camera mic.(subject to BG noise levels as well) Whoever uses the device, does it for a very specific kind of projects and a boom mic should be part of the deal (imo). If you take all the "trouble" and expense to shoot using that device, you might as well go the extra mile and get good sound (my 2c on the issue)

Hey, Anyone heard of this problem? I believe my P+S groundglass has
suffered some condensation/ or water/ fogging from shooting in high humidity. It seems to have left a sort of stain on the outer edges of the glass. As I was shooting it began to look like a heavy fog filter was being used - especially in the highlights. It does appear to be on the groundglass and not the protective glass. Any Suggestions??

Try and leave it in a hot place (in the car? if it is a sunny day). That should get all the water out of it. If the water left stains, you will have to have it open and cleaned (the prisms or the inside filters) My 2c.

Thanks Dan, I had it checked out today at Statton camera in Detroit. My P+S looked quite different from theirs. It was very foggy - prizms and mirrors. We pulled out the optical assembly and tried to clean it - it had an oily resedue on it and the tech there thought the ground glass had the same stuff on it. We thought maybe it was coming from oil or grease in the ball bearings surrounding the groundglass. Anyway, It's off to ZGC - I'm sure Gui
there will be able to make it "all better". Thanks again for your reply. , Peter.

1) Good idea to service it w/ ZGC.

2) Re: noise - all of our units are pretty quiet, but I've used units from other places that have had a bit more noise. If yours is on the quieter end, and there's any kind of background noise on your location, the gg movement should be drowned out. But you can always do a mic check to be sure.

Otherwise, using a hot-shoe shock mount and a wind jammer should take care of any noise.

But, as already suggested, if you can do it, a boom mic always works well and no noise should be picked up by that, even with the noisiest unit.
