But Nikon never made center filters so you had to use other brand ones. That isn’t true for the German lenses!Originally Posted by chassis
This is a Schneider CF III on a Nikkor SW 75/4.5. It works, it's usable, no problems.

nothing better than trying!!!
but seems that some are easely intermutable...
maybe wider angles and non super-angulon type designs will be more troublesome...
one question... has anyone tryed to DIY a center filter... glass... petroleum lamp... just wondering...
Wider angles? Rodenstock and Schneider recommend CFs only for lenses that cover at least 100 degrees. None of their lenses covers more than 120 degrees. If you want a wider lens, accumulate your small monetary units until you can afford Rodenstock Pantogonal or a Hypergon with spinning star. The spinning star is a mechanical CF.
If by non-super angulon types you mean classic wide angle lenses with small front elements, well, yes, they are more troublesome because of the difficulty of mounting a modern CF on one. There's an exception. R'stock made a CF for the Pantogonal, a yellow-green thing called Enixantos.
wider angles: 110, 115, 120 degrees... those are the wider of the super angulon type
by non super angulon type i meant super symmar xl ones
by troublesome i meant a higher difficulty to swap between filters and lenses of different brands
If the shoe fits, wear it. What matters is filter mount threading and filter factor.
I don't know whether this https://1drv.ms/b/s!AggQfcczvHGNnBX28ZyoWkE24Tqq is still on line, so here's my copy. Look at the list of lenses that take center filters.
DIY??? no one tryed??
cheers!!!!
If you want to try, look at the CFs supplied for B&L Metrogons.
I notest that the metrogon center filter does not have a soft transition between the unfiltered area (near the edges) and the start of the ND area... it seems abrupt...
Just for fun: i could use an old uv filter and try to smoke the central spot, i can try with different "smoking" : candles, gas, petroleum... or... maybe i could try other methods... printing digitally? analog veiling?
it´s not a thing i will depend on, but it could be a good thing for experimental things... For ex: making a center filter to substitute the propeller of the hypergon???
I know optical makers spend years and an enourmous amount of math to figure it out...
I think Corran has an experience with one of those.
There were also some star-like CF filters such as this one: http://www.digoliardi.net/skc/skc-filter-1.jpg
The rectangle in the filter just a reflection of a window in the scene.
Hummmmm!!! it seems doable... but maybe it needs some kind of rotation for evenness? a nd gelatin cut to size in a flower or propeller shape and some rotation??? or a divided exposure with movement in the filter?
the smoking appeals to me... maybe i can give it a go...
