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.
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
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
A) Wider 15 or 19mm base plate support bars.
B) Clip –On clamp ring to the front of the lens.
The problem of using creative adjustable filters has been overcome as
a result of South London Filter’s position in this product market
place. By closely observing the production problems outlined by camera
technicians, South London Filter has in co-operation with Van Diemen Ltd,
developed an affordable solution to the problem." No currently manufactured
matte box for use with creative grads and polarisers is able to offer
full coverage on 5.2mm & lower broadcast lenses holding non fixed,
independently rotating filters, unless 6.6” filters and matte box
The BWM 5.65 currently has the ability to hold two independent rotating
sections when directly attached to the lens, additionally when used on
bars a third 4.5” round rotating filter holder can be used (this
would usually be a polariser). Full coverage is achieved as a result of
the New 5.65” Square grads and polarisers, these have been manufactured
by leading filters manufactures including; Harrison & Harrison, Formatt,
Pancro Mirrors Inc & Schneider Optics, Ira Tiffen has also indicated
to me that Tiffen will manufacture theses filters as "special order".
All of the current filter trays have been manufactured as combination
trays, thus having the ability to hold two different filter sizes. If
you use (PV) 4"X 5.65" as your solid size all you have left
to consider is the Grad Size.....
4" x 4" / 4" X 5.65"
5.65" X 5.65" / 4" X 5.65"
4" X 5.65" / 5" X 5"
Arii GB I know have also produced 5.65" Sq Trays for some clients,
as this Grad size greatly increases the use of theses filters, on wider
