Thread: Filter stacking on 24mm 1.4G

  1. #1

    Default Filter stacking on 24mm 1.4G

    I'm planing to buy a B+W 10 stop filter (77mm) in BNS but find it hard to get one, my second option is to get a 9 stop Kenko ND 400 (77mm) and stack it with my Kenko Pro 1D CPL (77mm). If I can't find a 10 stop filter, here are my questions to those who have experienced this:

    1. Will stacking 2 filters, 9 stop Kenko ND400 and a Kenko Pro1D CPL on a 24mm 1.4G cause vignetting?
    2. Will the result of stacking those 2 filters be close to using a B+W 10 stop filter? Any significant difference?
    3. If stacking the 2 filters is ok, does it matter which one (CPL or 9 stop filter) to attach first to the lens? and will the metering method be the same as how to meter as if using a 10 stop filter?

    Thank you

    alternative:

    invest in Lee Filter System.

    get a Big Stopper and if you want to, CPL filter.

    I'm pretty sure stacking two filters on the 24mm will cause vignetting on a FF camera

    You will most probably get weird color casts from the kenko as well

    If you die die need 10 stops, then buy a 10 stop... why buy a 9 stop and stack on CPL to get 10 stops??

    You can always buy the ND110 new... new pricing is not that far off from BNS pricing anyway.

    On a side note, 9 stop and 10 stop not much difference if the main purpose is to take landscape water type shots. Unless its a really bright day.

    I think it is the reverse.. if it is a really bright day the difference between a 9 stop and 10 stop is a lot less... eg. 15s exposure vs 30s exposure..

    if it is not very bright, it makes a very very big difference... e.g. 10min exposure vs 20min exposure.

    Yes it will cause vignetting. How much depends on the filter thickness

    Hm. I think you may be right.
    But I still don't think theres a very significant difference between 9 and 10 stops. Of course if got the $ go buy the 10stop.

    For long exposure, one stop can be a lot of different in term the length of shutter speed, and you need good quality glass especially. Else shots are not usable after spending all the efforts.

    Thanks for the reply guys! Guess its best to get the 10 sops rather than stack with my cpl. The square filter is another option but Im more inclined to the screw type for now.

    Hi! I saw a b+w nd110 single coat filter at tk and its $145 with gst if i remember it right. Is there a significant difference in terms of pic quality vs the multi-coated one? Might as well buy a new nd110 instead of stacking filters to avoid vignetting. Thanks!

    How about using b+w nd110, do you also get vignette? Or just when using the cpl?

    if I shoot raw, the color cast can be corrected during post right or would it be difficult to correct?

    In theory yes but I have yet to test out 2 stacked kenko filters so I cant say anything about whether its easy or not.
