Good point... as long as you have an equally tiny lens to mount on it.

My old Olympus E-P1 with the 17/2.8 (that's about equal to 35mm on FX) was pretty good. The little Panasonic GM5 is so small it's pretty much invisible! I still wouldn't mind one of those with a pancake lens...
Quick edit. I suppose, given where I am, another suggestion for street shooting subtlety might be a Nikon 1
It's really hard to use a DSLR on the street these days. Especially the larger bodies. And, the size of current lenses doesn't help either.

I do feel a bit self conscious using my D610 for what little street photography that I do but, since I'm always carrying it, that is wearing off to a degree. I tend to use the 24/2.8D, which is a very compact lens, and shoot without raising it to my eye.
