At times I just go for a casual wander with a 1 prime lens thing. dSLRs and their lenses have gotten larger and larger so with casual outings like after a weekend brunch or sightseeing with the others etc. i don't really want to carry an SLR kit with 3 lenses. If it was just 1 prime lens, how do they compare with some of the premium compacts? Ricoh GR, Fuji X100, X70; and the film versions of Yashica T4, Contax T2, Ricoh GR etc .... Cheers.
