If you can use a SLR for street photography, why getting a RF in the first place ? The SLR offers more precise framing, a huge choice of lenses, access to zooms, better automatic exposure, AF or not and so on. Finally the lenses and the body are less expensive.

For some of us however, a rangefinder like the M8 cannot be replaced because we want something less obtrusive and because we prefer to frame through this kind of viewfinder. And because we like both the easy and precise manual focusing in low light is very and use of hyperfocal on a sunny day.
For these reasons, we are ready to accept filters, returning the body to Solms, paying an expensive body and lenses and even some extra.

Have fun.
