What camera do you recommend for street photography -- if any?
I have a Sony NEX-5N, and it's still a fun mirrorless cam for those times when I want high-quality shots on the street. It's very portable and easy to use one-handed. That said, I often end up using only my phone; there's a certain appeal to traveling light and getting to share your pics right after you take them.
The 5R takes great shots, but only if it has a good quality lens on it. The 16-50 kit lens is nothing special, the 18-200 is good but huge to carry around just in case there is something to snap. You really need to spend the money on a good lens the NEX cameras, whereas the RX100 straight out of the box is fun to use, easy to handle and takes excellent shots time after time.
I still think Fuji's current lineup is probably the best cross between a more lightweight shooter that offers a lot of flexibility in shooting options. They tend to deal really well with reviews when being looked at as a "fun" camera to shoot with, which is kind of the idea when it comes to street photography.
For pocketability the 20mm 2.8sony pancake is great. Just plan on getting a little closer and cropping in a bit in lightroom. If you are in dtown you have the bonus of shooting architecture without a lens change.
For day time I use my Minolta 35-70mm 3.5 paired with a focal reducer to simulate fullframe. This is a magical combo. I love my Minolta lenses and paired with the reducer really bring out that non digital look of an old film camera.
Nighttime, the Minolta 50mm 1.4 and reducer. Can almost shoot in total darkness. The reducer makes the aperture more like a 1.2 lens and at ISO1600 you can shoot in ultra low light.
Carl Zeiss Sonnar T* 35mm F2.8 Lens would be great too and have the benefit of autofocus, but unless you have an a6000 or A7 I don't trust a sony nex"s autofocus ability. And it is pricey
What I liked about it is that folks took me serious. In this day and age, I am going to opt for using my old Nikon D2H, which is a large professional camera with the 17-35/2.8, an equally large lens.
People are much more willing to give you the time of day when you look like you are a professional.
