So I'm starting out with 4x5 with a Schneider APO 150mm Synnar MC on a Chamonix 45N-1 4x5. I need contrast filters for BW and polarizer. I have 77mm B+W screw-on filters from my medium format camera system. Could I use these with a step up adapter? I believe the Schneider takes a 58mm filter. (Where can I verify the size?)

Would I be better off getting a couple of new filters to screw into the Schneider lens without the adapter? How do you deal with lens hoods with Lee vs lens mounted filters on 4x5?

How about Lee filter resin types? Does 4x5 lend itself better to glass mounted on lens filters or to Lee type? Does Lee affect hoods placement?

thanks. Alan.
