Rear lens slot in ND filters

[mipevo6]

Folks,

I am looking for a rear slot in filter for an ultrawide as you can use a standard Lee or similar system due to the size of the front element

Anybody recommend?

1) A rear slot in filter that is ND
2) A place that sells them

I think you might need to specify the lens Martin, since I'm not sure that they are similar sizes for different lenses.?

Is this any help? http://petapixel.com/2015/03/01/did...elatin-filter-slot-on-some-wide-angle-lenses/

Canon 11-24.

I think some of them come large size and you cut them to size (the petapixel article confirms this).

Something like this looks like it would be cheap enough to play about with? https://www.stagedepot.co.uk/lighti...sku=ENL-4180&gclid=CKytpcDiqc0CFQUq0wodR0kDvQ

I was hoping for something a little higher quality, but this looks interesting for a play at least

Thank you
