I am considering the 7-14mm - and I am curious if anyone has come up with any creative ways to mount an ND filter.

The only thing I can think of is use a matte box and slide in a 4x4 glass filter. But that is not possible with my setup. Any bayonet style / slip on filter holders that would take a Cokin style drop in filter. Is the lens even too wide for such a device?

It's a real shame Panasonic didn't think of this. Maybe they could of made a larger threaded lens hood?

( On a side note - why can't someone smart developer just invent super low ISOs? Why don't cameras have ISO 15, 25, 50, etc. It would make ND filters obsolete, which I'd love! )

Any ideas?

Thanks,
Angelo
