>>4276436bessas are great, but you can definitely feel the effect of the lower base length if you have ever used a leica. my leica m4p just feels so much easier to focus with compared to my rollei 35rf. i use the rollei 35rf if i'm hiking and only need infinity focus or if i'm staying slower than f8. if i'm trying to nail focus with a fast lens then it's much easier on the leica.
if i had to pick one it'd be the rollei 35rf for sure. the leica is fun but i use the other a hell of a lot more.
