thank for Tipp

Hello, last month i bought this one:
at U$31,
but now is even cheaper at U$22 (including shipping)
(67mm - 72mm outer)

http://cgi.ebay.com/Slim-67mm-Fader-ND-Filter-Neutral-Density-ND2-ND400-/330558411712?pt=Camera_Filters&hash=item4cf6d113c0

is branded as Lyshi
and i really love it, is quite useful, and it is slim as advertised
is a little bit greenish - blueish, but i actually like the image more, i think that it does improve the image to my taste in colors, so...
and even though i haven´t made any definition "side by side" test, at least at the gh2 screen, and the digital zoom that we can do to the recorded image, i don´t think there is any loss in definition

so i definetly reccomend this bargain, if you want a cheap nd fader

Greetings to all!, this is my first post (:

I got the 77mm 'Nature' Fader. It works pretty well as long as you don't go to the extreme stops (like most of these). The downside is the build quality, the rotation works a bit funky sometimes or doesn't work at all and needs to be fiddled with a bit - this was after some heavy use. Also the markings don't match up which may not matter to some folks but irks me a bit sometimes. Using it primarily with the Nokton25/0.95 - slight color shift, will turn purplish with ugly banding on the extreme end (sometimes but NOT all the time I find). I personally found a good balance by using Smooth-2-2-1-2, and white balancing religiously. When I used it with Nostalgic it seemed to accentuate the yellow-greenish tint - felt like I was in a perpetual flashback montage on really warm sunny days :-)

I also have a Lyshi 67mm which doesn't get as much use as I like to use 77mm step up rings - I may be using that one a bit more as i'm having trouble with the Nature rotating. The Nokton with the 52-77 step up and Nature 77mm and also an 82mm collapsible rubber lens hood - makes people look sacred :-). Lyshi is nearly or about the same performance as the Nature.

I also have another no-name 52mm Fader which i quickly snap on my Nikkor's but haven't used that in ages.

Is there any new info on these cheap fader NDs ? I am about to buy step up rings for all my lenses to match my samyang 35mm 77mm front thread so my 52mm trusty kenko nd filters won't be much use and I'd love the convenience of a variable ND, but only if there is no sharpness drop and no horrible tints. And I can't afford Singh Rays, hence, the revival of this topic.

greetings personal-view crew. long time lurker, new to posting :D
@Vitaliy_Kiselev how are you finding the Lyshi and Tian Ya?

@TheMonk

On ebay. if you search carefully, you could find wholesale options even ones allowing to select any rings combinations you want.

Most of these cheap vari filters don't work beyond 50mm on GH2s. Cheaper ones might be worse.
