Hi,

I've recently just bought a Hoya 52mm ND 400, which is great and does the job perfectly, but I was thinking about pairing it with a circular polarizer as well to reduce the reflections in long exposure water shots... but... can you stack them? I hear about stacking filters, but I'm presuming this is with the slide in filters with holders? Can anyone shed any light on this?

Thanks!

Tom
 
You can, but you will likely get some pretty bad vignetting. Try it and see.
 
So I simply buy a hoya circular polarizer and screw them together? Sorry, wasn't very specific, was meaning to ask more about the mechanics of it. My ND400 doesn't seem to have a filter on the front?
 
Logically the more filters that go onto the front of a lens the less light to get to the sensor. Both filters mention have a specific purpose and not really designed to work in conjunction with each other.

Not 100 % accurate. Most landscape togs will at some point use either an ND grad or ND and a polariser, but usually in a lee system or similar. This is why lee make the polariser adapter the screws onto the front of the foundation holder.
The ND slows the shutter for the long exposure and the polariser cuts the reflections in water or glare off foliage.

To the OP I don't know if the ND has a filter thread, if it does, then screw a polariser into it, if it doesn't, but a polariser that does so you can screw the ND on the polariser, although I'm not sure if that will effect the polarising effect.
