Mattebox & Filters Question

Hi tim,

You have a Cavision bellows with a croziel flag, Is that right? I was thinking of 16:9 have you had any experience with that version? I also just got stadicam flyer how compatable do you think the 16:9 would be with rig.

All the best, Greg.

P.S by 'clip-on' did you mean matte box or flag?

Otherwise, go with a matte box and square filters. You can't beat the ease-of-use, quick changing of filters, and the ability to rotate some filters for effect.

If you can't afford glass 4x4 filters and matte box (a considerable investment,) then look into SLR style plastic filters. I've used my Cokin P-Series filters on a DVX100 numerous times. You can buy a kit with the filter holder and some starter filters at any camera store for under $40.

Tim,

I have a Cokin p setup laying around somewhere that I was going to experiment with. (mostly the 4x4 polarizer) did you run into much of a problem with sunligh reflecting around inside the filter setup? Just thinking of that or a Cavision mattebox later or a really good 82mm polarizer and adjusting it without putting finger prints on it inside the stock lens hood.

having used both, the cavision is crap. the chroziel is a much more precise and better built unit. you'll use the chroziel on you next couple of camera, won't say that about the other.

when it comes to follow focus units, its all about how much slop they have. the good ones have almost none, and as you go down in price, the slop goes up. not to say you can't use them, its that I hate cheap tools making the job harder then it has to be.

as for the quick release, the chroziel has a sony v mount on the bottom so it will mount with a sony plate. I don't like sony plates. they have a tendency to grab on only on side, yet let you think its good because it locked in place. while I normally catch this, I didn't two weeks ago an put my camera on the floor :( :(. see the the thread about DIY handle repair. using most tripod plates directly on the camera means you have this big piece of metal sticking out, and often into you. something I only do if the camera plate didn't make it to the shoot. its a lousy way to work.

mate I use the 450 with the 251, and for the first time ever one of my jobs went bad because I used my Tiffen Polariser in conjunction with it. I've used the filter ever since getting the camera and mattebox, basically it gave everything a magenta cast. I have since found out this is a common problem with 3ccd cameras, have you found anything similar?
