Does anybody know the filter size or if at all possible to put a filter on the 7-14mm?

it is not foreseen to attach filters to this lens. No thread !

Yeah, you would have to fabricate a holder.

One of the pluses for the 9-18 is it takes filters. The 7-14 has a built in petal shaped lens hood and a slip-fit lens cap. As said no thread.

+1. Built in lens hood, so no filter thread

Those are not necessarily mutually exclusive - some built in lens hoods have threads.

No filter for the 7-14 which is why I got the 9-18mm (plus it was a lot more affordable).

^^ I would prefer the 7-14mm based on pure IQ, but this lack of filter options is a real turnoff, I use NDs a lot for motion effects with wide angles. Oly 9-18mm it may just have to be, as you said Peter it also saves me a fair few hundred $..

Will the Olympus 9-18mm autofocus on a GH2? Do you need an adapter?

The Micro Zuiko version will work fine, no adapter needed...
