Need odd size filters

[narsuitus]

I need 34.5mm magenta, cyan, and neutral density filters.

Can anyone recommend a source for this odd size?

Singh-ray makes custom sizes and colors.

How about one stepup/down rather than several custom filters...

The german company Heliopan offers filters in 34.5mm from stock.
(Though I'm not sure about cyan.)


Alternatively in case you can get hold of the filter rings, you could insert self cut PET filters.
