The Chrosziel 805 system is a 4 X 5.65 swing away mattebox "system" that accepts 5X5 filters. With 2 stages you could use 2 5X5 filter trays
and 5X5 filters when you need to rotate 2 stages with a lens wider than
4.9mm to avoid vignetting. Or use 4 X 5.65 trays and up to 4 stages with
less wide lenses.
You can easily mix and match filters and trays. It is modular so you can add and subtract stages. There is also a clamp on version.
This has been available since NAB 2002 and is the most popular mattebox system for the F900/27F/Viper.
Hope this helps

While we're on the subject, just two comments :
1/. For wide angle use, aren't the Chrosziel 412 (sunshade) and 415 (mattebox) specifically designed for 4.5mm lenses with 1 fixed (PV) and 1rotating (5x5)? This is the setup we'd originally spec'd for our Varicam but have put on hold pending point number 2...
2/. We're in Barbados which puts us neither in the US market or the European market - we're an ex-British colony, but we're much closer to the US. We have noticed a significant variance in the pricing of Chrosziel items between the US and Europe. On average, the European price, and I'm talking LIST prices out of Chrosziel’ s own online catalogue, when converted and compared to US RETAIL prices, are substantially lower. I'm talking between 30 and 40% in some cases. Is there any justifiable reason for this? I have spoken to our US supplier and they have said that there's not much they can do - there seems to be two totally difference pricing schemes.
Traditionally, items are usually cheaper in the US, but this does not seem to be the case here, and the differences are dramatic. Is there any reason for this? Is the price list on Chrosziel site out-dated or wrong? Are there import duties on these items?
I'm not meaning to upset anyone here, just trying to see if this is indeed the case, and also, as in point number 1, to confirm that we're correct on our assumptions on those Chrosziel items.
At South London Filter Ltd we have introduced the NEW BWM5.65 (Broadcast
Wide Mattebox 5.65") .
The New BWM 5.65 has been developed to overcome a common problem encountered by videographers wishing to use creative location camera filters to their full potential without compromising the wide focal length capability’s of current broadcast lenses of 5.2mm and under. Designed with the owner user or rental facility in mind the BWM 5.65 can be mounted in two standard ways.
A) Wider 15 or 19mm base plate support bars.
