    Got some Lee grads and plan on stacking these on top of the CF.

    When I got the filter a few years ago I did a test with some FP100c with and without the filter using camera movements to to show the edge of the image circle. The left photo is without the filter (I only have a bad iphone photo right now, but if you like I can upload a scanned one when I get back home this weekend).

    You can see without the filter there is a large drop off, and it is reduced with the CF 3, but not completely. The horizon on the photo is straight through the center of the lens, with front rise to show the edge of the image circle while the lens is stopped down.

    Also, here are links to a photos that shows the full frame with negative film:

    I hope this helps.

    That is a very noticeable drop off where you would expect it least (the sky). Did you stack a GND as well?

    It is only a 1.5 stop filter - but its close enough.

    If you do the maths for light fall off at cos^4, none of the Centre Filters will compensate exactly for the light fall off on any lens - even if the CF is identified to match the lens by the manufacturer.

    Centre Filters are almost as rare as hens teeth - so if you think you have something which will get you close - buy it and use it.

    You can always keep an eye open for the recommended filter.

    Many thanks for everyone's help and advice!

    I have gone with a iiic of the auction site. It looks in mint condition and the seller has good history.

    That extra 1/2 stop might come in handy when I stack a polariser and GND (90% of the time for landscapes).

    I have used a IIIc with a 47 & 58 SA XL, in my experience it is adequate for both.

    A couple of things you might want to bear in mind too.

    Stacking filters on these ultra-wides runs a really risk of vignetting, even using a slip on filter holder (such as the Lee) over the CF.

    Using a polarising filter on lenses with such a wide field of view also has the potential for uneven polarisation of the sky.

    All the best

    Matt,

    In the instant photos in my post there is no grad filters applied. This was a test only of the fall off with the Schneider CF3 on the 58mm Super Angulon XL. I have found that instant film it a bit more like slide film when it comes to dynamic range. I have not noticed any large fall off when using the CF3 filter on negative film.

    OK the results are in!

    Obligatory shot of the back garden...

    The scan of the whole negative makes the scan too dark as the scanner tries to darken the sky (didn't use a grad):

    However its even, and there is no need to correct for fall-off

    Scanning the lower half of the negative and omitting the sky gives a much better scan:

    Lower corners don't show any fall-off, so all good.

    That looks really even to my eye

    2-pass scanning to the rescue:

    TBH it only rescues the lower half. The sky is full of grain...

    Hi Nathan,

    Many thanks for your advice.

    What filter system do you use? Need to buy an 86mm adapter ring now for my Lee filter holder. Would it have to be the wide angle adapter ring? There only seems to be the standard adapter ring for 86mm, so would this work?

    Thanks Matthew

    Standard adapter rings and 100mm filter holders will vignette, a lot, with the 58mm.

    Lee makes an 86mm to 100mm "donut" adapter that, as far as I have ever been able to tell, can only be purchased from Europe. I could be wrong. Then, you use it with their 100mm adapter that is designed for wide-angles (it slides over and tightens onto the outside of the lens/filter).
