What lenses

[chrisli]

If all that matters is the retro look, you can keep the X100. It's a nice camera.

You don't need a rangefinder camera to do 'street photography'.
Heck, people do 'street photography' with a MF box camera.

Why not you personally get a feel of the cameras before plunging in?
Weigh the pro and cons against your own needs, and ignore what others have to bloody say.

You are right, well maybe, I was finding a reason for myself to own a Leica...hahaha. They are 2 brand of cameras I have always wanted to own a Hasselbald and a Leica eversince I started photography many many years ago, but never find the right reason to own any of them, so this could be a reason.
So this is a "want" and not a "need".
Anyway, I was always a little shy to use a DSLR to shoot people, maybe I am a little timid and is afraid people might be angry and come after me...hahaha. Then when I got the X100 it looks like fun.. and was looking at the Leica...

Hi chrisli.. thought its a crude way how some street photographers put it, it is actually very true.

The shorter your focal length, the bigger size of balls you will need.

No offence to anyone here
