Thank you all for the feedback thus far. Some variety of the GR1 is starting to appeal to me. Is the shutter quiet compared to the XA4? About the same?

Here's what's driving this line of questioning... For stealthy street shooting, I want a 35mm compact with a wide prime, and a fast but quiet shutter. (I think 1/500 is the fastest that the XA4 is capable of.) Zone focusing is what works best for me. Need lots of DOF. As such, I'll probably need to shoot high speed film.
