CAVision Filters any good?

It sounds an interesting deal. I would like to go with quality optics so a bit cautious about the CaVision filters.

My question though, is these only come as 4X4... For widescreen, shouldn't I be needing the 4X5.65 (or panavision size) filters?

Anyone know the real difference here with the extra 1.65" ?

We have made a low cost filter kit with the budget concious HD user in mind:

Century DV/HDV Filters - Schneider Optics

Now you can buy Schneider quality at a reasonable price.

You don't need the 4x5.56 filters for widescreen but it all depends on how wide your widest lens is or the diameter of the lens.

A note to all about Cavision filters: I rolled the dice last year on their new lineup of 4x5.56's (an ND1.2 and a Grad .9). The quality was HORRIBLE. The ND grad looked more like a purple party color than ND. It literally was that off-color. It could have been a cool color effect but it was anything but neutral.

The straight ND was significantly better but still had a VERY strong purple cast to it. It would be something that'd be very hard to time out in post and was thus completely unacceptable. I sent them both back immediately for a full refund from Adorama.com. Go with Schneider and you won't regret it. Buying quality gear only hurts once. The other stuff keeps hurting.
