In terms of long exposures, which film (available in 120) has the least reciprocity effect? In other words which film has the longest exposure time without need for compensation?

Hands down it's Fuji Acros100 in 120 size. Use it all the time. No correction right out to 2 minutes.
Best, Peter

I'll second Peter's choice. Longest exposure for me was 3 minutes and got the results I wanted. Great film.

Good Morning, Doug,

Peter is right, but T-Max 100 is also excellent for long exposures and is a lot cheaper than the Quickloads Acros comes in.

Even after 2min you only need to add 1/2 stop with acros. I have used it for exposures 15mins+ easily.
