Thank you everyone. Herculaneum and Parnassus are on my list to see as well.

I checked the manual for the camera and it says to use circular instead of linear polarisers. Something to do with the way the TTL metering system works.

I think I'll invest in some ISO 100 film for the trip instead. When I was in Rome a few years back, ISO 100 was not easy to find. Lots of kodak gold ISO 200 and 400, but not being local, I didn't know where to look for a photography specialist.

I haven't tried slide photography yet. Still trying to get it right with film. That's a challenge for another time.
