Lately, I have been walking the streets with a minimal setup, an old Fuji XT1, with both the XF 23mm 1.4 and the XF 18-55mm. Included, a couple of polarizers and a small table top Manfrotto tripod. It is light, but very complete setup, like a swiss knife. I usually carry the beautiful and most useful 23mm lens attached to my camera, and one the situation requires, I change to the other lens, usually for architectural or landscape shots, mounted on the little tripod. I mean, you can get very creative with this setup.
In other words, you can get great looking colors using the now old X-T1, the autofocus speed is very appropriate for street photography, and 16MP is a lot for daily use. I could see how pushing ISO 6400 could get challenging, but if you train yourself on the importance of not pixel peeping, you get still very nice looking pictures. I have added a couple of street portraits from Santa Ana where ISO was that high, and you would agree they are nice looking and noise is hardly noticeable at plain sight.
You'll be amazed to know that when the Fujifilm X-T1 was released, it cost over $1,200.00. Now, you can find very well taken care second hand X-T1 for less than $400. Believe me, I'd recommend ten times to whoever is new to photography to look at these deals, because you get awesome pro features at a much cheaper price, rather than buying new entry level consumer plastic cameras for double the price. I have seen similar deals: nowadays: an entry level camera with two kit lenses for less than $700, when you can put that money on both an X-T1 and the amazing 18-55mm lens, and you'd be more than high quality served.
Enough said. Enjoy shooting.
