Here's a few neat Cokin filters.

Prism (Ref. 219)
Diffuser Light (Ref. 820)
Diffuser 1 (Ref. 830)
Diffuser 2 (Ref. 840)
Diffuser 3 (Ref. 850)
Sunsoft (Ref. 694)
Softwarm (Ref. 696)
Warm 81B (Ref. 027)
Sepia (Ref. 005)
Blue 82A (Ref. 023)

I use a sunsoft(694) as part of my "film look" package. Works like a charm adding that warmth and softness that's part of the film response curve to light

Hi Frank

How much is the Sunsoft (Ref. 694)? and where can i find one here in the Vancouver area.

A 72mm for the XL1

You could try Leo's Camera on Granville. Actually, I think they only carry Lee filters. Kerrisdale Cameras carries Cokin filters, but you might have to get it specially ordered from them. They are in the east, upper section of Coquitlam Center.

I don't think Leo's has that in the screw-in type. The screw-on types other than UV and polarizers are quite new. I'm sure Leo's have the adaptor type though (A and P size). If you go to my website, you'll see a flashing ad with filter thread sizes on it. That's a good source. It's in France. To see what's available in the screw-in type, go to:

Okay, here's that link that sells Cokin screw-in filters. The sizes are from 27mm to 86mm. By the way, they're quite inexpensive.

got a question for you guys,

I assume you can do those same effects in post, so is there an advantage to shooting something with the filter instead of doing it in post?

only if I don't have to do any rendering...otherwise, it's a push.
