X100S does seem the one for AF, but bigger than I thought.
GR if Low light AF not taken in to account wins out for size and fitting in pocket.
Gah! Gr cheaper, legend of a camera.
But will I get street shots in low light?
Let say I'm in Soho, it's 10pm and through the window of a really cool looking bar I see some cool ambient lighting and an interesting scene.... one of those perfect Edward Hopper type shots.
With my D5300 and 35mm 1.8 G DX I nail it. I get focus on the humans through glass at night, ambient lighting only and even at ISO 6400 it looks great and prints a meter by a meter if I wanted to with great through frame acuity and depth rendering, plenty of detail.
Would the GR be up to the job...?
I use the GR snap option. No need for AF because of delay. Snap is like a wink of the eye just like a film camera. I set IOS 6400. Set F28 --- set meters to 2.5m or 5m and will have a wide DOF .
There will be some noise compare to a DSLR, but I like grit, especially b/w images ala Daido Moriyama.
I'll buy the GR if I can get the shot described above, ambient neon / indoor light only and through glass, AF through glass and also prints look good even at ISO 6400.
I do know F2.8 is 1 and a 1/3 stop less than F1.8. Fuji X100 only a 1/3 stop less than 1.8 as F2.
but will it fit in a pocket
Yes, pocket lint will be an issue.
Day or night I always hold my GR with a wrist strap. Power always on---finger on the shutter ready to snap instantly.
An aside: One can fine tune GR DNG raw files in camera. I can crop, covert color to b/w and b/a to color adjust EO in 1/3 steps to +1 and -1. There are many other options which I can't list now.
The best part is no need to take-out the SD card inset it to a laptop nor computer.
You can PP the DNG raw files any place any time Worldwide.
