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?

i'm sure single ND filters would be sharper but i'm in the market for a vari-ND. lightcraft or singh-ray ...

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.

interesting... good to know. i guess now the thread can be totally on topic for the OP

I didn't think it would have the same inconsistencies as using a CPL on a UWA. 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

basically a vari-nd is 2 CPL's put back to back. when you rotate one, it creates the ND effect.

It was a screw on - one that jordanlee recommended. cheapo one off ebay that actually works quite well.

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

that's how vari-nd's work on UWA's.

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

Interesting. If I see correctly, it's just a filter that has "multiple densities"?

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 (http://photography-on-the.net/forum/showthread.php?t=140826)

The filters can be bought from www.2filter.com (http://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.
