I've Rollei Retro 80S in bulk, and it's pretty smooth. So is Pan F and XP2.
But I'm torn between wanting smooth slow films to minimise the effects of the tiny negative, and wanting faster films just because it's that kind of a camera and a lot of its lenses are f3.5 and f4. I can well see myself using the 48/1.2 and 60/1.5 most of all though, as they are the most interesting lenses. Restricting DoF isn't so easy with all these short focal lengths. I was quite surprised at how well the Kentmere came out, really quite good for the price, but certainly needed more spotting than HP5+ would.
