    For vari Nd it is very simple. See if got color cast, how much color cast, and at what stop will cross banding appear. And the wider the lens the more propensity tonsee cross banding.

    For resin rextangular nd, key is to watch out for color cast, and also evenness of the nd.

    THe difference is how much color cast, what kind of color cast. And cross banding after how many usable stops.

    And there is NO rectangular vari-ND.

    If you look at the Kenko, color cast only starts seeping in at 9 stops. On Tiffen vari-nd, there is not much color cast throughout the range. Cross banding is minimal on the Tiffen, even at 12mm (on crop), cross banding starts to be noticeable at 7 stops. On the cheaper Vari-nd at that angle, cross banding starts to come in at 3-4 stops.

    You really do get what you pay for. Personally Emolux vari-nd is junk and is something I will never buy.

    You have either bought the Emolux or are going to buy it.

    In that case, please proceed, no need to squabble over which is better or which is not. Tianya and Emolux are not very good. But Tianya is acceptable if you are not too hiam, I haven't seen the Emolux.

    Imho all filters add some form of cast especially when stacking. So I stopped stacking and do exposure blending now.

    I got mine in B&H in New York before the price hike. 189usd. Now it is slightly over 200 usd in USA. Cathay sells at 350 IIRC. Kenko vnd price has come down slightly. Check with TK for the current pricing.

    You can always Google for the pics. but if you happy can already. Emolux to me is junk. Most serious landscape photographers will not even go near anything by Emolux. Because they do not manufacture their own stuff. IIRC, Nature from China makes their varid nd and rebrand it for them. Any one who wants that fiter can buy the China versions for dirt cheap instead and get the same thing.

    If you already bought it, my condolences.

    Hi,

    I am thinking of upgrading my current Tianya GND and would like to seek some advice. Is it common to mix different brands of GND and the colour cast is still manageable? I thought of buying a LEE 0.9 Soft and a HiTech/Cokin 0.6 Hard. Feel free to advise, thanks! ^^

    Ur filter holder most probably will not be able to hold different branded filters. Either because of size or thickness. And u also increase the possibility of light leakages.

    For the filters mentuoned, there should not be any problems as long as you stick to 85mm wide filters. Tianya filter holder is a direct copy of cokin P holder. But do note that if you start using uwa filters or ff cam bodies you will start running into problems with the 85mm holder and filters.

    Thank you all for the sharing thus far.

    I have a question, is there a difference if I buy an 82mm ND and do a step-down to 77mm for my lens?
    Will this reduce vignetting given the filter 'covers' more area in front of the lens.
    One other consideration will be flare / light leakage as the filter is now effectively further away from the lens due to the step down ring?...

    or just heck care and buy a 77mm.

    Depends on the lens used and the design of the lens. Sometimes using a 5mm larger filter with a step down ring actually gives you more vignetting, if you are using a UWA lens.

    I would like to ask a noob question, doesn't seem to be that mentioned in the 25 pages.

    For the sunrise / sunset, will a ND or GND filter be preferred. Or it depends on the blue hour or contrast to the foreground ?
    If I only have a choice due to budget contraint / splitting resources, would the ND filters be suffice ? Looking in getting a new brand that has quite a good review.
    I'm still venturing into difference type of photography.
