Cigarette1 >> you'd better try to find some Hoya filters or so, I'm almost sure they'll be less expensive than Sony's
For example I paid 50€ for mine (too expensive IMO but I needed one as soon as possible) while the same one (+neutral filter) costs 155€ by sony :shock:
Concerning the adapter, I was forced to order it on the web (sony once again) and I remember the one for the P92 is also very hard to find in regular shops
Dingo >> your's will be huge, mine is only 58mm but I already find it too big for my camera
