Post your 9 or 10 stop ND photos

I have that Vari-ND slim or say for wide angle lenses and it vignette badly on my 16-35L, so i am sure even that blue/gold one will be the same if it is in same thickness of that Vari-ND.

The Vari-ND is 14.2mm for 82mm version, and 14.2 or 10.5 for 77mm version.

The Gold-N-Blue is available in 77mm either 4.8 or 8.5 mm thick. So it should give way less vignetting. The bad thing is that the Blue/Gold isn't available in 82mm, which is needed for the 16-35. I'm not sure if the Cokin Sprocket Ring version is possible to use.

OK, so with that blue/gold it will be better vignetting then, but i need 77mm because i have 16-35L mkI not mkII, and in all cases i will buy a step down ring adapter from 82-77mm and see, say it may add 2-3mm thickness depend on that adapter ring.

That makes sense as the Vari-ND is in essence a 2 filter stack.

Fortunately, all the lenses I intend to use it on share a 77mm filter thread (17-40, 24-105, 70-200/4).

Then at least, you have top quality vignetting.

BTW: the blue/gold polarizer is also available as a threaded slim mount variant, which presumably won't vignette (as badly) on UWA's.

The Gold-N-Blue is a nice filter in the thin mount. I haven't found a situation to really use since I've been using my Singh Ray Color Combo alot.

If you buy the thin mount, you shouldn't have problems with vignetting at all.

I wouldn't even bother with a step down ring. I just use adhesive putty. It doesn't stick but, it works!
Here's an experimental image with the Singh Ray G-n-B 77 thin on my 16-35 II. Remember it's experimental but, it worked!

You should have no problem with vignetting on your 17-40 with the thin mount. On the other hand, if you buy the Singh Ray Vari-N-Duo in the thin mount and can deal with a little bit of vignetting, you should be ok.

The problem with the thin mount however, is that it doesn't take a filter holder for your grads and such. So you'd have to hand hold those, which can be an issue with very long exposures and/or when using filter sandwiches. While the attached filter holder may vignette on your UWA's, it will probably be fine on WA's and tele's.

OK, i will see if i really need that B&G filter for some applications. in all cases i really don't use polarizer that much nowadays, only ND and GND.

Experimental, schmexperimental. This is why I am eyeing this filter!

That's what I usually do. Hand holding a GND takes some patience and practice. Try it sometime.

Here's a Youtube video of Tony Sweet using this exact same technique. It's called "feathering". Enjoy!

LOL!

Here's a nice long exposure shot with the Singh Ray Color Combo and Singh Ray 3 stop Reverse GND handheld.
It's 30 seconds @ f/8 and I didn't have coffee yet.

Whatever works for you Tareq.

Thanks for the link! I'll check out the other videos as well.

The thing is that if the normal mount doesn't vignette (too badly) with the 17-40, I think I would prefer it over the slim mount, as it would still give me the option to use a filter holder with longer focal lengths.
