>>3630931Depends how much money matters. You can still get R2s for ~$500 with some patience. I can't imagine going for an M6 with their current prices which from what I've seen are ~$2k. The m6 is not 4x the camera the R2 is. Be aware the R2 only focuses to 0.9m. The R2a/R2m focuses to 0.7m.
Also personally...I can't imagine walking around with $2.5k+ kit all the time. I've done it in the past and it's caused me to baby cameras...which makes them pointless. If I can't take my camera anywhere and not really care if it gets stolen/broken then I shouldn't have that camera. I can stand to lose a $500 Bessas and $200 Voigtlander lens. A $2000 M6? Nah, that'd fuck me up.
