| ND Filters
Hi all,
I was just wondering if anyone here uses ND filters (either straight or grad, screw-on or plate).
I was thinking about getting a ND filter for my 10-22, but I'm not sure where to start. I was looking into getting a 2-stop screw-on ND from maxsaver, and maybe a grad-ND plate.
Any idea how much a grad-ND plate would be locally? And I guess a 77mm 2-stop ND filter?

When I got my Vari-ND, there was a warning saying it won't work with a UWA. I tried it, and it creates a big discrepancy of the ND effect between the edges and the middle.

Were you using a screw on? Or one of the Cokin/Lee plates?
There's always Lightroom and the gradient/ND tool I guess- but I figure it's one less step in post if I had the filter in the first place.

Seeing as this thread is kind of dead, I figured I'd make a last ditch result for some answers-
B&H and Adorama seem to be sold out of Lee filters more or less. Any places locally that carry the plate filters from Lee/Singh-ray? It looks like Broadway/Lens&Shutter don't carry plates. Last time I was in Leos they didn't seem to carry any at the time.
Senna, does Beau carry them?

i use a 10stop ND (B+W) from time to time (if there's uhh ample time to do long exposures), and have a 2 stop soft grad plate (cokin). i don't have much of a UWA, just 24mm on a FF and there's vignetting (?) when using either plate or the 10stop.
kerrisdale carries a line of the cheaper cokin plate filters

It was a screw on - one that jordanlee recommended. cheapo one off ebay that actually works quite well. eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

so did it have inconsistencies because it was low quality? or that's just how vari-ND's work on UWA's?

I'll try to take a picture tomorrow. Can't demo it at night.

It would make sense to see those discrepancies in a UWA, considering a CPL by itself shows it let alone two.
I did a bit of snooping, and with my particular setup it looks like I can get away with Cokin-P/85 type filters for what I want. This thread cleared things up: 10-22 EF-S & Grad Neutral Density Filter_ sample
The filters can be bought from www.2filter.com, based out of New Hampshire. I'll hear from them tomorrow to see how much shipping is to Canada, otherwise it'll be the old Blaine pickup.
Edit: Just get it from B&H. A bit more expensive, but easier to order from.

sorry, I did some reading, and a vari-nd is a linear polarizer with a CPL mounted on top. by rotating it, they both cut out opposite spectrums of light, thus creating the ND effect.
I don't find a CPL by itself does too much banding on a UWA unless you point it at the sky. but I never did too much testing with that.
